San Alfonso del Mar: 5 Key Milestones of the Lagoon that Launched Crystal Lagoons® Technology to the World

More than a world record: How the project that “seemed impossible” validated a business model that is now redefining global real estate development.

For real estate developers and leaders in the hospitality industry, innovation is not just a buzzword; it is the difference between a project that stalls and one that redefines the market. In the modern history of real estate amenities, there is a clear “before and after” marked by a specific turning point: the inauguration of the crystalline lagoon at San Alfonso del Mar in Chile.

Located in Algarrobo, about 90 km from Santiago, Chile, this second-home complex was built around an approximately 20-acre crystalline lagoon powered by Crystal Lagoons® patented technology. From that point on, the paradigm changed forever. San Alfonso del Mar was not just the first large-scale project; it was the ultimate proof of concept, the living laboratory that demonstrated to the financial and real estate world that the “lagoon effect” was real, profitable, and sustainable.

San Alfonso del Mar: the lagoon that changed the amenities industry

Before San Alfonso del Mar, the idea of maintaining a crystalline body of water, even of limited size, was economically unfeasible. The innovation developed by Fernando Fischmann made it possible to create and operate monumental lagoons with low water, energy, and chemical consumption, opening up an entirely new amenity category.

Today, that first lagoon triggered an expansion to more than 1,000 projects in different stages of development and negotiation across over 60 countries, consolidating Crystal Lagoons as a global benchmark.

The 5 key milestones of the San Alfonso del Mar lagoon

Milestone 1: The first crystalline lagoon with Crystal Lagoons® technology

San Alfonso del Mar was the world’s first project to incorporate Crystal Lagoons® technology to create a large lagoon with turquoise waters and high transparency next to the Pacific Ocean.

For developers, this meant something unprecedented:

  • Testing, at real scale, a technology that made it possible to build lagoons of virtually unlimited size.
  • Transforming a traditional coastal site into a second-home resort with controlled and safe “beach life.”

This first pilot became the “before and after” for the company and for the entire aquatic amenities market.

Milestone 2: Guinness World Record and unprecedented scale

In 2007, the San Alfonso del Mar lagoon was awarded the Guinness World Record as the world’s largest crystalline lagoon/pool, thanks to its dimensions:

  • More than 1,013 meters in length.
  • Approximately 20 acres of surface area.
  • 250 million liters of seawater.

Although Citystars Sharm El Sheikh in Egypt later surpassed it, the symbolic impact of the record remains: it proved that Crystal Lagoons® technology could successfully operate at scales that were previously considered impossible.

For the positioning of real estate and hospitality projects, this record meant:

  • Turning the amenity into global news.
  • Associating the development with a worldwide milestone, raising its perceived value and tourist appeal.

Milestone 3: From pilot to one of the most successful second-home resorts in the region

Originally, San Alfonso del Mar was conceived for around 400 apartments. The success of the crystalline lagoon led the project to grow to approximately 1,400 units, all with views of the ocean and the lagoon.

The lagoon:

  • Transformed Algarrobo into one of Chile’s most successful beach resorts.
  • Positioned the complex as the most successful second-home resort in the region, doubling the initial sales prices.

For a developer, this milestone demonstrates that a crystalline lagoon can:

  • Accelerate the sales velocity.
  • Justify higher prices per square meter.
  • Extend the high season and overall occupancy.

Milestone 4: A global media icon that positioned the brand

More than two decades after its inauguration, San Alfonso del Mar continues to appear in international media, rankings, and lists of “places you must see at least once in your life.”

Media outlets from different countries have described it as:

  • “A portion of ocean encapsulated” or “the most impressive swimming pool in the world.”

This media magnetism turned the lagoon into:

  • The global calling card for Crystal Lagoons® technology.
  • A case study in organic marketing for the company and for the resort itself.

For developers and hospitality operators, this translates into:

  • Global reach without an equivalent additional investment in media.
  • An amenity that generates constant organic content (photos, videos, social media) created by the visitors themselves.

Milestone 5: Platform for global expansion and model for new developments

San Alfonso del Mar was not just a one-off success: it became the reference model that allowed Crystal Lagoons to scale its business to more than 1,000 projects in different stages across over 60 countries, from the Middle East to the United States, Asia, and Europe.

From this project onward, the technology was applied to:

  • Residential and second-home developments.
  • Luxury resorts and hotels.
  • Public Access Lagoons® projects, also known as PAL® developments, a public-access model that opens up new revenue streams through ticketing, events, dining, and retail.

For investors and developers, the strategic message is clear:

  • San Alfonso del Mar served as a successful “prototype,” proving the technical, economic, and commercial viability of the technology.
  • This success story now supports large-scale projects around the world, reducing the perceived risk for banks, funds, and hotel chains.

The lagoon that opened a new chapter for resorts and amenity-driven developments

San Alfonso del Mar proved that a large-scale crystalline lagoon can:

  • Change the destiny of a project and an entire city.
  • Generate added value, faster sales velocity, and global positioning.
  • Be the starting point for a scalable, sustainable, and highly profitable technology for real estate and hospitality developments.

For developers, the question is no longer whether a Crystal Lagoons® amenity works, but how to replicate the “San Alfonso del Mar effect” in their next project and turn an amenity into the true value driver of the master plan.

Outstanding news

  • The lagoon powered by Crystal Lagoons® technology transformed the tourism offering in Orlando, the most visited destination in the U.S., and positioned Evermore as a benchmark for hospitality developers around the world.

Orlando has theme parks, dining, golf, and an entertainment offering that is difficult to match. What it lacked was a major beach experience within the city.

Evermore Orlando Resort decided to change that reality. It transformed part of a former golf course into a 7.8-acre turquoise oasis powered by Crystal Lagoons® technology, bringing an idyllic beach experience to a place where none had existed before.

The result is not just a visually stunning environment. It is a business model that combines luxury with a relaxed lifestyle, positioning itself as a benchmark in the most competitive tourism market in the United States.

A turning point for Orlando tourism

Evermore Bay was built on part of a former golf course, transforming an underutilized piece of land into a vibrant waterfront attraction. Its white-sand beaches and calm waters offer an alternative to coastal trips, without waves, currents, or long-distance travel.

The concept reaches a massive market. Orlando welcomed 75.3 million visitors in 2024 and remained the most visited destination in the United States.

For these travelers, the lagoon offers something new:

  • White-sand beaches just minutes from the theme parks.
  • Swimming, kayaking, and paddleboarding.
  • Cabanas, restaurants, and waterfront bars.
  • Venues for weddings, meetings, and corporate events.
  • A resort experience designed for families and groups.

Why does this amenity transform the project’s profitability?

For a real estate developer, aesthetics are key, but the numbers are what ultimately matter. The experience at Evermore demonstrates that the beach concept directly drives commercial performance:

  • Longer stays: What was once envisioned as a one-day break between theme park visits has become the centerpiece of the trip. Guests stay longer at the resort and spend more at its facilities.
  • New revenue streams: With more than 150,000 square feet of event space, the lagoon serves as a setting for weddings and business meetings. It also features 12 dining options, water activities, and world-class golf courses.
  • International recognition: The project has received awards from Condé Nast Traveler, USA Today, and Meetings Today, validating the value of innovation in the guest experience.
  • Guests themselves describe the experience as a Caribbean getaway in the heart of Orlando. They say they chose the resort because of the lagoon and value being able to see the bottom, swim in calm waters, and wake up to an expansive blue view.

A model that diversifies revenue streams

Evermore was designed as a comprehensive tourism ecosystem. Its current phase features nearly 1,500 rooms across vacation homes, villas, apartments, and the exclusive Conrad Orlando. Meanwhile, the master plan includes more than 10,000 rooms across the full development surrounding the lagoon.

The project generates revenue through:

  • Hotel accommodations and vacation residences.
  • Twelve dining venues.
  • Water and recreational activities.
  • Events, weddings, and corporate gatherings.
  • Two golf courses.
  • Cabanas and premium waterfront experiences.

For a developer, this point is key: the lagoon does not function merely as a visual feature. It acts as the centerpiece of the project, extends guest stays, and connects different business units.

Awards that support its value proposition

Evermore Orlando Resort was recognized by USA Today 10Best as one of the best new hotels in the country and received a Best of Meetings Today Award for its contributions to Orlando’s recreational and corporate offerings.

In 2025, Condé Nast Traveler also named it one of Orlando’s best resorts, highlighting its beach experience, dining, golf, and accommodations for groups.

A benchmark for the hospitality industry

Evermore Orlando Resort demonstrates how a lagoon powered by Crystal Lagoons® technology can transform the positioning of a hospitality development.

It goes beyond simply adding an amenity. It creates a reason to choose the project, stay longer, and spend more within it. That effect redefines hospitality standards and strengthens the presence of Crystal Lagoons in an industry seeking memorable experiences, differentiation, and new sources of profitability.

Orlando already had entertainment. Evermore gave it a beach.

  • The Epperson project redefined the concept of master-planned communities in the United States. The combination of Crystal Lagoons® technology and the PAL® model transformed a residential development into an entertainment destination capable of driving real estate demand and generating new revenue streams.

Imagine building a residential development on an inland site, far from the coast, and getting people to pay an entrance fee to visit the very place where you are selling homes.

It sounds almost too good to be true. Yet that is exactly what Crystal Lagoons achieved in partnership with Metro Development Group in Wesley Chapel, Florida, through its Epperson project.

Opened in 2018 with an impressive 7.5-acre crystalline lagoon powered by Crystal Lagoons® technology, the initial plan was traditional: an exclusive space for residents. But the visual impact and demand were so massive that the team made a bold decision.

They decided to transform part of the operation toward the Public Access Lagoons® model, also known as the PAL® model. They opened the lagoon to the general public for an entrance fee, and the result exceeded all expectations.

The strategic shift: More value per square foot and accelerated sales

Opening a residential space to the general public might sound contradictory to some developers. Think about it for a second: would it affect the neighborhood’s exclusivity? At Epperson, the exact opposite happened.

Opening the project under the PAL® format worked as a living commercial showcase. Thousands of visitors paid for a ticket to spend the day at a Caribbean-style beach just 35 minutes from Tampa, and while they enjoyed the water, they discovered the real estate project organically.

The data confirms it:

  • Price increase: Homes sold at a 21% higher price compared to direct competitors in the area.
  • Sales velocity: The pace of home sales rose 57% above market averages.
  • Customer acquisition: The daily flow of visitors dramatically reduced the cost of acquiring potential buyers.

Numbers that speak for themselves: US$3.4 million in a single season

The success in home sales and recognition in real estate rankings was only half the story. The other half lies in the profitability generated by the water infrastructure itself.

Through a ticketing model that varies by season, age, and time of day, the lagoon became a coastal lifestyle park. Even during a challenging year like 2020, operating at 40% capacity due to health restrictions (800 people allowed at the same time), the project recorded impressive figures:

  • Massive attendance: Nearly 91,695 visitors during the season.
  • Direct revenue: Revenue was estimated at around US$3.4 million from ticket sales, water activities, and rentals alone.

The public was not only paying for admission. The recreational offering expanded to include kayak and paddleboard rentals, inflatable obstacle courses, and premium spaces such as private cabanas, VIP areas (known as Aquabanas), and Tiki-style areas that can rent for more than US$300 per day during peak season.

Today, the destination includes a swim-up bar, merchandise shops, food trucks, and expanding restaurant offerings. A complete commercial ecosystem that generates continuous cash flow.

The “lagoon effect” in sales and rankings

Epperson’s commercial strength is also reflected in industry rankings.

Over the years, the community has been recognized among the top-selling residential developments in Florida and the United States. In 2023, it ranked No. 36 among the country’s top-selling master-planned communities, according to RCLCO, while in previous years it also ranked among the state’s highest-performing communities.

This positioning confirms a trend that developers are watching with increasing attention: buyers value experiences and lifestyles that cannot be easily replicated through traditional amenities.

Why are real estate developers looking at this case?

Epperson’s business model demonstrated something key for the industry: amenities no longer have to be a cost center funded only through residents’ HOA fees.

By incorporating Crystal Lagoons® technology and enabling controlled public access, real estate developers gain three clear advantages:

  1. Monetization from day one: The lagoon generates independent operating revenue while the real estate project is being built and sold.
  2. Brand positioning and prestige: The project enters and consolidates its position among the top spots in the most important national and international sales rankings (RCLCO and John Burns), attracting highly qualified buyers and investors.
  3. Land flexibility: It makes it possible to bring beach life to lower-cost inland sites that do not have access to the ocean.

Epperson showed that the future of the real estate industry is not only about building homes, but about creating destinations people want to return to again and again.

  • Media outlets such as Daily Mail, New York Post, The Sun and This is Money highlighted the impact of Mirada and Epperson, two developments that confirm the power of crystalline lagoons as drivers of sales, community, and real estate differentiation.

Beach life no longer depends on living by the ocean. That idea, which only a few years ago seemed aspirational, is now being highlighted in international media as a concrete trend within the United States real estate market.

New York Post, The Sun, Daily Mail, and This is Money have put the spotlight on Mirada and Epperson, two communities developed by Metro Development Group in Florida that have turned their lagoons powered by Crystal Lagoons® technology into the main attraction. This is not just about an appealing image. It is about an amenity that sells, brings people together, and changes the way residents experience a residential project.

Mirada: The lagoon capturing the attention of the U.S.

Mirada, located in San Antonio, Florida, is home to a 15-acre lagoon powered by Crystal Lagoons® technology, considered the largest man-made lagoon in the U.S. Its scale is equivalent to nearly 150 NBA basketball courts and offers activities such as kayaking, paddleboarding, relaxing beach areas, a swim-up bar, and a floating obstacle course.

For a real estate developer, the key point is not only its size. It is the impact it generates. According to coverage published by the U.S. edition of The Sun, Metro Development Group describes the lagoon as one of the main drivers of interest in its communities, because it creates immediate excitement and offers something that cannot be found in a traditional neighborhood.

Epperson and Mirada: from amenity to purchase driver

Epperson was the first community in the United States to feature a crystalline lagoon of this kind, paving the way for a new category of residential development: communities that offer a resort-style experience every day.

Mirada took that model to another scale. Metro Development Group highlighted that the community is now making national headlines for its 15-acre lagoon, while Epperson and Beachwalk also stand out as benchmarks for the concept of “lagoon living” in Florida.

This phenomenon makes one thing very clear: a crystalline lagoon does not function as a simple add-on. It functions as the heart of the project.

What makes this model so powerful?

  • It turns inland communities into beach lifestyle destinations.
  • It creates a visual identity that is easy to communicate.
  • It increases appeal for buyers and residents.
  • It activates activities year-round.
  • It builds community, permanence, and a sense of belonging.
  • It differentiates the project from traditional amenities.

The “lagoon effect” is also reflected in the rankings

The commercial impact of developments powered by Crystal Lagoons® technology is also reflected in real estate rankings. In 2025, three communities featuring this technology ranked among the 50 top-selling communities in the United States, according to RCLCO: Sunterra, ranked 5th; Mirada, ranked 14th; and Lago Mar, ranked 47th.

For the industry, this data matters. In a competitive market, where developers need to justify pricing, accelerate sales, and create real differentiation, a crystalline lagoon can become a powerful commercial argument.

An increasingly strong footprint in the United States

The success of Mirada and Epperson is not an isolated case. Crystal Lagoons has a growing presence in the United States with residential, hospitality, and public-access projects, including

Why is the industry betting on this technology?

Beyond the visual appeal that captures media attention, there are solid operational and financial reasons behind this sustained growth:

  • Water and energy efficiency: They consume up to 33 times less water than a conventional golf course and use only 2% of the energy required by a traditional swimming pool filtration system.
  • Land transformation: They make it possible to turn inland sites into locations with value comparable to beachfront properties.
  • Proven value appreciation: Lots and homes surrounding the lagoon register consistent price increases, often outperforming area averages.
  • International recognition: An innovation backed by multiple global awards in innovation, sustainability, and intellectual property.

The new standard for real estate amenities

International coverage of Mirada and Epperson confirms a trend developers are already seeing on the ground: buyers are not just looking for a home. They are looking for experience, a sense of community, and a more memorable everyday life.

That is where the value of Crystal Lagoons lies. Its crystalline lagoons transform real estate projects into destinations, create a competitive advantage that is difficult to replicate, and deliver something the market immediately recognizes: living with a vacation feeling every day.
