We actually spend more time doing trail maintenance in Rock Creek than hiking it, so for the "other national park" hike as part of Hike with PATC in 2023, we went down to Rock Creek. Our loop started at the Nature Center and went clockwise, for a little over five miles.
On the western side of the park, we started off at Fort Russy, which we have visited before, and then return to the outer loop, spending time on paved trails. Since we never do trail work on paved trails, that section was new to us. We then crossed over to the Valley Trail. Personally, I enjoy the valley trail, since it follows the creek. We then crossed back over, returning to the Nature Center.
We enjoyed nice weather, and a chance to get out without carrying any tools!
