The Rock Run area campground is open annually from the first weekend in April to the last weekend in October. Reservations are now required through the entire season. Campers will check in at the bathhouse and pick up camping permits at the bathhouse.

The campground has 13 basic sites, nine tent-only sites and six sites with electrical hookup. Each campsite has a picnic table, fire ring and lantern post.

Firewood Alert

Firewood may be purchased onsite at the bathhouse for $5. Please do not bring firewood into the park. The firewood we sell is purchased from a local vendor in order to limit the spread of forest pests such as the Emerald Ash Borer. Help us keep our trees safe by not bringing firewood into the park. For more information, please visit The Maryland Park Service Firewood Policy webpage​.

No Tent? No Problem!

You can have an RV or camping trailer delivered and set up on your site prior to your arrival. Contact the park office at (301) 271-7574 for details on how to rent the camper of your choice from a local, experienced RV rental company. This is an extra service and is not included in your camping reservation.​

Tips for Camping in Black Bear Country

Bears do visit our campgrounds. Here are a few simple reminders to help keep you and the bears safe and ensure that you have an enjoyable stay.

  • Never keep food in your tent.
  • Store food and garbage out of a bear's reach by storing food securely in the trunk of your vehicle.
  • Remove your trash from your site daily and place in the campground dumpsters.
  • Remember to secure your pet’s food also
  • If a bear comes into camp, don't feed it! Scare it away by making noise.
  • See a park employee to get more detailed information on how to camp in black bear country or visit: Living With Black Bears.
