Dive into the wonders of the underwater world at the unique Downtown Aquarium, where you can interact with the ancient legends of El Dorado in the Sunken Temple, sink to the bottom of the neighboring sea, and catch glimpses of offshore rig divers in the Underwater Rig. Tour the marsh and bayous of the Gulf Coast and encounter the alligators, turtles, bullfrogs, and more in the Texas Bayou. Step inside the sunken hull of a 17th-century Spanish Galleon and see the giant octopus, a moray eel, clownfish, and the diversity of species the ocean world has to offer at the Shipwreck. Explore the lush environment of the dangerous tropical life of the red-bellied piranhas and venomous freshwater stingrays in the Rainforest. Step into Discovery Zone and come face-to-face with electric eels, seahorses, and a dazzling array of colorful fish. Interactive monitors let you further explore coral reefs, the arctic seas, and the mysteries of the deep ocean. You may even meet one of our Ambassador Animals up close during the daily Animal Encounters.

What began as a hobby has bloomed into one of Houston's most popular tourist attractions, The Beer Can House. Over 18 years, the house disappeared under 50,000 flattened beer cans of different varieties for practical and decorative reasons. The can motif was only one aspect of the now-iconic visionary art environment. The yard is filled with plants and flowers that hang from the trees, occupy ceramic vessels, and grow in raised beds. As the neighborhood has changed, the property remains a time capsule of Houston’s vernacular architecture from the early 20th century, with a surprise around every corner.
