Access Issue: RAIN, WET ROCK CLOSURES; The sandstone around Castle Rock is fragile and is very easily damaged when it is wet.
Details
WET ROCK: Holds rip off and climbs have been and will continue to be permanently damaged (like Donkey Dong and countless others) due to climbers not respecting this phenomenon. After a heavy storm the rock will remain wet, sometimes for several days. PLEASE DO NOT CLIMB AT CASTLE ROCK during or after rain.
Access Issue: Trails are closed from sunset to 6:00 am.
Details
Trails close at sunset. Give yourself enough time to be back at your vehicle (or campsite if you're staying at one) before dark, or the rangers will fine you.
