The Robins Nature Center

Part of Richmond's Maymont Park is the Robins Nature Center. The center focuses on "Run of the River" and highlights the ecology of the James River. It includes fish, crabs, snakes, turtles, and apparently river otters which we totally missed. Most of our time was spent playing on the giant climbing structure and hopping on logs and waving to turtles in the play area. 
At $8 for adults and $6 for kids, this center is super affordable, but much smaller than we had hoped. It makes for a perfect stop to break up a road trip for an hour. We somehow managed to get a diaper blow out from one kid, and a super random bloody nose from another in a span of five minutes while here. Stop in during a hot day in Richmond or  as a reason to get out of the car while passing through!
