Recreational opportunities include hiking, fishing, camping, canoeing, horseback and mountain bike trails, as well as picnicking for individuals or large groups in the park’s many popular pavilions.

Trail closure in the Woodstock area

The trail commonly known as the “MORE fun” trail is closed until further notice, see map below. After evaluation of an existing bridge on the trail, it has been determined that this bridge will be removed. Patapsco Valley State is working on the purchase of a replacement bridge. Due to the span, this new bridge will be constructed of FRP (fiberglass reinforced plastic) and be approximately 30' long. The existing wood at the site will be used to construct the necessary bridge abutments. Thank you for your cooperation and your support of Patapsco Valley State Park. ​
