Gavin's Point Aquarium

At Gavins Point National Fish Hatchery

You can't miss our aquarium when you're driving on Hwy. 52 to Lewis and Clark Lake.  This 13,000 gallon facility has a free admission and is a nice cool place to stop on a hot summer day.  We typically have 40+ mostly-local species of fish, amphibians, and reptiles on display.  You'll also see fossils from the local area and lots of educational signage corresponding to the displays. The gift shop is open Friday-Monday during much of the summer too. 

The aquarium parking lot offers easy access to the paved trail system that runs along Lake Yankton and Lewis and Clark Lake.  Park here and launch on a long bike ride or walk with the dog along these well-maintained trails.
