Moss Grande Bouldering

Please do not drive on the roads to Mesteño Canyon when they're muddy, e.g. after a rain storm or from snow melt. These fragile grasslands two-tracks quickly become widened and rutted when driven in these conditions. When the roads are muddy the Forest Service would prefer we stick to the graveled K-600 road (Mills Canyon Rd) and boulder at the zones in the main Mills Canyon area. If you do choose to drive out when roads are muddy, STAY ON THE ROADS, IN THE MUD. DO NOT DRIVE AROUND MUDDY SECTIONS--STAY ON THE ROADS PROPER.

Also, please do not drive on any closed roads. The closure signs are brown carsonite flexible signs. See the map below showing the closed road and the appropriate way to drive to the Mesteño Canyon areas.

Please do not climb on actively wet or recently wet sandstone. Holds more easily break off and problems will be permanently damaged. After a heavy storm, the rock can remain wet, sometimes for several days even though it may not appear wet. PLEASE DO NOT CLIMB IN ROY during or for up to 36 hours after rain/snow. A good rule of thumb is that if the ground near your climb is at all damp, then do not climb.
