Local guidance
General guidance Private park: sign in and pay the day fee. No local wet-rock guidance was found for this area. The general rule for sandstone: most areas need 2 to 3 days after rain and up to a week after big storms. If the ground at the base is damp, the rock is too. Climbing: wet sandstone ↗
- Rock Sandstone
- Group Hard sandstone: red for 24 h after rain, caution to 48 h (72 h in winter)

Check the rock yourself
Rain gauges measure rain, not rock moisture. Sandstone is weak when wet and holds water long after the surface looks dry, especially on shaded or seepy faces. If the ground is damp, the rock is too.
Is it actually dry?
Field checks before you tie in
- Is the sand at the base dry? It dries before the rock does; damp sand means wet rock.
- Are the trail and the ground at the cliff base dry? If not, don't climb.
- Look for dark damp patches, moisture behind flakes and inside cracks, and fresh sand on holds.
- Shaded walls, spots under trees and grooves that channel water stay wet much longer.
- Sun and wind dry rock fast; cloudy, calm, humid days slow it down, and winter drying is slow.
- After long, soaking rain the rock can stay wet inches deep. Give it extra time.
- If any part of the route, base included, is wet, pick another climb.
- Not sure? Climb rock that isn't affected by rain, like limestone or granite, until it dries.
