OSMP has closed the Royal Arch Trail to conduct extensive maintenance to reroute the popular trail around areas prone to significant erosion. Since the trail is located in a steep area, re-aligning the trail to minimize ongoing erosion and avoid sensitive wildlife habitats will require extensive, ongoing trail repairs, and will include the building of several large stone structures.
To help protect visitors and OSMP trail crews, the Royal Arch Trail is closed 24-hours a day, 7 days a week. This long-term closure of the Royal Arch Trail is expected to continue into the fall. OSMP understands the impact this extended trail closure will have on open space visitors, but it is necessary to help complete trail maintenance as quickly as possible.
