Moody Gardens is a non-profit educational destination in Galveston, Texas, established in 1986 by The Moody Foundation on land owned by the City of Galveston. Spread across 242 acres, the campus is anchored by three glass pyramids, each dedicated to a different environment: rainforest, marine life, and interactive science exhibits, drawing roughly 2 million visitors a year.
The centerpiece is the Aquarium Pyramid, which opened in 1999 as one of the largest aquariums in the world at the time. Standing about 12 stories tall, it holds approximately 1.5 million gallons of water and is home to more than 10,000 marine animals, including sharks, seals, sea turtles, and seven penguin species, organized around exhibits representing the Gulf of Mexico, South Atlantic, South Pacific, North Pacific, and Caribbean regions.

Inside the Aquarium Pyramid
Visitors move through galleries modeled on five ocean regions, encountering sharks, eels, sea turtles, and a two-story, 30,000-gallon Gulf Rig exhibit that recreates the ecosystem around an offshore oil platform. A separate Caribbean tunnel holds about a million gallons on its own, letting guests walk beneath rays and reef fish.
The pyramid is also known for its penguin colony, which includes King, Gentoo, Chinstrap, Rockhopper, and Macaroni penguins housed in a chilled habitat near the entrance, one of the more popular stops for families visiting the aquarium.
Beyond the Aquarium
Moody Gardens is more than one pyramid. The Rainforest Pyramid, open since 1993, is a 10-story glass structure filled with roughly 1,000 plant species alongside otters, monkeys, and ocelots, while the Discovery Pyramid offers rotating science exhibits and motion-simulation experiences.
The property also includes Palm Beach, a seasonal water park built with imported Florida sand, a ropes course and zip line, and a golf course redesigned by Peter Jacobsen, making Moody Gardens a full-day destination rather than a single attraction.
