Beautiful park along the Arkansas River
Riverfront Park is a large urban park in downtown Little Rock, Arkansas that provides 11 blocks of beautiful green space along the Arkansas River and offers plenty of activities for kids and adults. It's an interesting place because you can see the actual "little rock" (or, in the case of the early French explorers, "la petit roche") that gave name to the capital of Arkansas.
The park is obviously a nice place to go for a stroll but it also has several attractions for the more culturally-inclined. The First Security Amphitheater is an outdoor concert venue where they hold evening concerts in the spring and summer and there is also a pleasant sculpture garden adorned with flowers and streams and even a small water park where you can spend a fun (and, importantly, free!) morning playing with the kids.
