Route Overview by Grade
Black Cliffs shines in the 5.8–5.11 range — the sweet spot for gym climbers moving outdoors.
5.6–5.8 (Beginner)
The lower-angle slabs on the east end of the main wall. Good for first outdoor days — positive holds, directional bolts, reasonable runouts. The basalt texture grabs well in cool conditions.
5.9–5.10d (Intermediate)
The largest concentration of routes. Face climbing on featured basalt — edges, pockets, and short crack sequences. Most routes are 40–55ft with 5–7 bolts. This is where most gym climbers find their outdoor footing.
5.11–5.12 (Advanced)
Steeper pockets and crimps on the overhang sections. Basalt pockets can be sharp — tape your fingers on sustained pocket pulling. The 5.12 routes require committed movement and good footwork on smaller holds.
Best Seasons for Climbing Black Cliffs
Black Cliffs faces primarily south — which is ideal for winter sun but brutal in summer.
Best months: March–May and September–November Avoid: June–August afternoons (rock surface can hit 100°F+ in direct sun) Winter climbing: Possible on sunny days above 45°F — some of the best uncrowded sessions happen in February
