Summer is, well, a hot time at Rock Creek Park. There are many activities, new and already established, to keep you busy within the confines of the city’s best nature spot. (For more ideas, visit and click on the
“Ranger-led Programs” tab and and
click on the “Get Involved” tab.)

Frisbee Flinging Fun

This informal Frisbee group will play Ultimate if enough people show up. All ages and abilities are welcome. Meet at Picnic Grove No. 24 across from the Tennis Center on June 2 and 30, and Aug. 11 at 10 a.m.

Fun Run

Join a Fun Run of 3-to-4 or 5-to-7-mile loops every other Sunday from June 9 though Aug. 18. Meet at the Nature Center for this trail run, open to all ages and abilities. This is a great way to figure out how and where to run in the park. The runs start at 10 a.m., but come at 9:30 a.m. if you want to learn the basics of running on a trail.

Pickup Soccer

Meet at Picnic Grove No. 24 across from the Tennis Center on June 16, July 14 and Aug. 11 at 10 a.m. for an informal game. All ages and ability levels are welcome.

Geology Hike

Experience Rock Creek Park’s harder edge on June 8 and 22, July 6 and 20 and
Aug. 3 at 10 a.m. with the guided tour “Let’s Rock: Introductory Geology Hikes.” Meet Geologist-in-Park Chelsea Lewis at the Nature Center for a three-mile ramble to learn how geology is connected to history, the forest and the water supply.

Pitch In

Beth Mullin of the Rock Creek Conservancy suggests one of the best ways to enjoy the park is to get the family together and volunteer. Currently, the conservancy is clearing English ivy from park trees. “It’s actually really fun,” she says. “It’s just you and the tree.” The group has removed the vine from 1,400 trees so far.
