One of my favorite places to visit.
I have been visiting the Tennessee Aquarium for about 6 years now, and I just can't help but go back.
Originally it was just the River Journeys building with a smaller saltwater exhibit in it. A few years ago, they added Ocean Journeys to it, included penguins, a HUGE saltwater exhibit, a butterfly house, and more.
The price is great, and the location is even better.
I have been involved with ocean life for years, and this is, by far, one of the best aquariums I have ever been to. There is always something there for everyone.
A tip: Opt for the behind the scenes tour! It's relatively inexpensive, and everyone loves it. You get to go where others can't from the pumping systems of both buildings to behind the scenes of exhibits, the special quarantine/research area, the feeding area, and the best part is you get to feed snacks to the saltwater exhibit in the River Journeys building. Kids will LOVE it.
I would recommend it to anyone. The price is unbeatable for the exhibits, and the aquarium is set up so that it is easy to walk around, and no one is ever left not being able to see the exhibits.
