Heads up!
Due to a winter full of freezes and thaws, there has been significant rockfall at the Mary’s Rock tunnel on Skyline Drive. Shenandoah National Park will be closing Skyline Drive between mile marker 31.7 and 33 to perform maintenance at the tunnel. The park will begin work on May 4th and estimates the closure will last two weeks. This will effectively close LIttle Stoney Man cliff during this time, since the detour would be extensive.
