Entertainment

A project that began as plans for an inland beach destination northwest of Houston is about to become a place families can actually visit.

Grand Magnolia Lagoon will officially open Saturday, Sept. 5, at 200 Strawberry Spring Drive in Magnolia, bringing a four-acre crystal-clear lagoon, white-sand beaches and water recreation to a growing part of the Houston region just in time for Labor Day weekend.

For Magnolia-area families — and residents of Cypress, Tomball, Waller County, The Woodlands and communities across northwest Houston — the opening creates a new option for a beach-style day trip without making the drive to the Gulf Coast.

It also brings full circle a development My Neighborhood News first reported in March 2025, when the nearly $30 million lagoon project had recently broken ground and was still more than a year away from welcoming swimmers.

Now, the water is ready.

What Visitors Can Expect at Grand Magnolia Lagoon

Grand Magnolia Lagoon is designed to offer both relaxation and more active ways to spend a day on the water.

Visitors will find white-sand beach areas and lagoon swimming zones along with complimentary beach loungers and umbrellas. Those looking for something more active can take advantage of kayaking, stand-up paddleboarding, an Aqua Course floating obstacle course and sand volleyball.

Hammocks, relaxation areas, music and entertainment add another side to the experience for guests who would rather spend the afternoon along the shoreline than on the water.

Food trucks are also planned at the property, along with a full bar serving both alcoholic and non-alcoholic beverages.

The mix is intended to make Grand Magnolia Lagoon more than a traditional swimming pool. It is being positioned as a public-access beach destination where families can spend several hours — or an entire day — swimming, playing, eating and relaxing.

How Much Are Grand Magnolia Lagoon Tickets?

For families planning a Labor Day weekend visit, general admission starts at $25 and includes lagoon access, white-sand beach access, seating and loungers, free parking, and access to kayak and paddle boat rentals, subject to availability.

Junior tickets are $15 for younger guests, while children age 4 and under receive free admission with family supervision.

Some water activities carry separate charges. Kayaking and stand-up paddleboard sessions are offered in 30-minute increments, while the Aqua Course provides access to the floating obstacle course. Life jackets are required for those activities and are provided by the lagoon.

For the Aqua Course, participants must be at least 6 years old and 42 inches tall.

Grand Magnolia Lagoon recommends purchasing admission online before arriving. The attraction has said that if tickets sell out online for a particular day, only limited gate admission may remain available.

That could be especially important during the opening weekend, when curiosity surrounding one of the Houston area's newest water attractions may draw visitors from well beyond Magnolia.

A Project More Than a Year in the Making

When My Neighborhood News first reported on the development on March 27, 2025, Magnolia Lagoon had recently broken ground on a privately funded, 40-acre site owned by Land Tejas.

The centerpiece was always envisioned as a four-acre Crystal Lagoon, developed through Houston-based Lagoon Development Company in partnership with Crystal Lagoons U.S. Corp.

Early plans called for four white-sand beaches, a tropical swim-up bar and floating obstacle course, along with paddle boating, kayaking and sailing opportunities through the National Sailing Club.

The project was initially expected to open for swimming in May 2026. Its Sept. 5 debut means residents have waited a few extra months for the gates to open — but the arrival of Grand Magnolia Lagoon still gives the region a new outdoor recreation destination before the unofficial end of summer.

“Our mission is to bring the beach to the suburbs,” Lagoon Development Company CEO Uri Man said when plans for the project were announced. “The experience of crystalline waters, white sandy beaches, and numerous activities in a PAL™ development is what attracts people from far and wide and what makes it a truly successful destination.”

That idea is at the center of the lagoon concept: creating the atmosphere and recreation associated with a beach vacation in an inland suburban setting.

Magnolia Joins the Houston Area's Growing Lagoon Map

Grand Magnolia Lagoon is part of a much larger wave of crystal-clear lagoon development around Greater Houston.

When the Magnolia project was announced, it was expected to become the sixth Crystal Lagoon in the Houston metropolitan area and the second fully public lagoon-based entertainment district developed by Lagoon Development Company following Angel Lagoon in Dayton.

Other lagoon projects associated with the development group include Balmoral Lagoon in Humble, the first swimmable Crystal Lagoon in Texas; Lago Mar in Texas City, a 12-acre lagoon; and Angel Lagoon in Dayton, another public-access destination.

“These joint ventures allow us to expand our PAL™ projects into strategic areas,” Iván Manzur, Senior VP of Sales at Crystal Lagoons US Corp., said when the Magnolia project was announced, “and with them, Crystal Lagoons will total more than 70 projects in different stages of development and negotiation in Texas.”

The growth reflects a broader trend across the Houston suburbs: developers are increasingly using resort-style recreation, trails, entertainment districts and destination amenities to create places that serve both nearby residents and visitors from across the region.

For Magnolia, that could mean something more than another place to swim. Grand Magnolia Lagoon has the potential to bring new visitors into the area, support surrounding development and give families another reason to spend their recreation dollars closer to home.

The Lagoon Could Eventually Be Only the Beginning

The lagoon itself was envisioned as the centerpiece of a much broader mixed-use entertainment district.

Earlier plans for future phases included an outdoor amphitheater, luxury apartments, resort-style hotels and waterfront restaurants surrounding the lagoon.

Those concepts point toward a longer-term vision in which Grand Magnolia Lagoon becomes an anchor for dining, entertainment, lodging and residential development rather than operating only as a seasonal swimming attraction.

Plans previously associated with the project also explored environmentally focused infrastructure.

The development was considered a potential candidate for Eco-Heated Lagoon technology, which can reuse waste heat from nearby data centers to warm portions of lagoon water. The concept was intended to create warmer swimming zones while reducing the energy traditionally needed to heat such a large body of water.

The lagoon itself uses Crystal Lagoons' patented filtration and disinfection technology, designed to maintain clear, swimmable water using a low-energy filtration system and pulse-based disinfection process.

Those longer-range ideas will be worth watching as the area around Grand Magnolia continues to develop.

For now, however, residents finally get to experience the part of the project they have been watching take shape: the beach.

Planning a Visit to Grand Magnolia Lagoon

Grand Magnolia Lagoon is located at 200 Strawberry Spring Drive, Magnolia, TX 77355.

General tickets begin at $25, junior tickets begin at $15, and admission is free for children age 4 and younger with family supervision. Parking is free.

Families should purchase tickets online in advance when possible and check Grand Magnolia Lagoon's official website for the latest operating hours, availability, attraction requirements and weather-related updates before heading out.

From Groundbreaking to Opening Day in Magnolia

For residents who remember hearing about the project when it was little more than construction plans and renderings, Saturday's opening marks an important milestone.

What My Neighborhood News first covered in 2025 as a proposed four-acre stretch of turquoise water is now preparing for beach towels, kayaks, children racing toward the water and families settling into loungers for a day close to home.

And while the development's larger story — including future restaurants, hotels, entertainment and other surrounding projects — may still have chapters ahead, Labor Day weekend gives Magnolia residents their first opportunity to see what all that construction has been leading toward.

Grand Magnolia Lagoon opens Saturday, Sept. 5, 2026.
