The Texas State Aquarium, located in Corpus Christi on the Gulf of Mexico, is the largest aquarium in Texas and one of the largest in the United States. And it's no wonder why! The facility focuses on the wildlife of the Gulf of Mexico and the Caribbean, and it is home to an impressive array of aquatic life, including sharks, stingrays, sea turtles, and more.

The aquarium really leveled up in 2017, when it opened its Caribbean Journey expansion and roughly doubled in size. That addition brought in a 400,000-gallon shark exhibit, a jungle aviary, and a 4D theater, so there's a lot of ground to cover. You can also swing by Dolphin Bay, a 400,000-gallon saltwater habitat that's home to a small group of Atlantic bottlenose dolphins.

Visitors can explore the different exhibits at their own pace or take part in one of the many educational programs offered, from behind-the-scenes tours to overnight stays. There's also plenty on-site for grabbing a bite between adventures. As a working wildlife rehabilitation facility, the aquarium also rescues and rehabilitates injured sea turtles and raptors, so a visit helps support that work. Whether you're a first-time visitor or a seasoned pro, the Texas State Aquarium is sure to make a splash!

Tennessee Aquarium

Located in downtown Chattanooga on the banks of the Tennessee River, the Tennessee Aquarium opened in 1992 and features exhibits of freshwater and marine life from around the world. Fun fact: when its original River Journey building opened, it was billed as the largest freshwater aquarium in the world.

As home to more than 12,000 animals representing nearly 800 species, the Tennessee Aquarium is a must-see for animal lovers of all ages. The Aquarium's two buildings, River Journey and Ocean Journey, showcase different aquatic habitats. River Journey traces the Tennessee River from its Appalachian headwaters down toward the Gulf of Mexico, while Ocean Journey, added in a 2005 expansion, dives into saltwater life. Keep an eye out for the Secret Reef, the aquarium's largest tank at around 618,000 gallons, where sand tiger sharks and sea turtles cruise past.

In addition to its animal exhibits, the Tennessee Aquarium also offers educational programs for school groups, families, and adults. The Aquarium's IMAX theater shows documentaries about marine life and environmental topics, and its conservation arm works to protect native fish, turtles, and other species across the Southeast.

Whether you're an animal lover, a nature enthusiast, or just looking for a fun day out, the Tennessee Aquarium is sure to please.
