Rock Creek Nature Center & Planetarium

Rock Creek is a great place for cycling, skating, horse riding and exploring the old mill and the site of the Civil War battle at Fort Stevens. As well as the Nature Center’s guided hikes, there’s the highly entertaining Creature Feature program (4pm Fri), which takes a close look at the park’s wildlife. Inside Peirce Barn, kids can try on period clothing and play with 19th-century toys. The planetarium (on the park’s western edge) hosts several free shows: check the website for details.
