Quality routes on excellent rock make Thunder Ridge one of Colorado's best granite climbing areas.


Thunder Ridge is a gem of an area first developed by Steve Cheyney, Kevin McLaughlin, Glenn Schuler and Mike Johnson in the late 1990's. Home to plentiful routes and boulder problems on phenomenal stone, it's a granite paradise

Access issues

Thunder is a very special place, but it's proximity to private land (the approach crosses private property) means that continued access to the area depends on how well climber's respect and adhere to the fragile access terms that were thankfully negotiated between local route developers and land owners. When visiting Thunder Ridge it is vital that one refrain from camping at the signed parking area, hike only on the road beyond the gate, and at all times remain quiet and respectful of land owners in the area.


From the Abbey Road turn-off into the town of Westcreek (14.1 miles north of Woodland Park on CO-67), drive 0.2 miles to a T-intersection and take a left. In 0.5 miles, take a right hand turn to head west on Stump Road. Stay on Stump for 2.0 miles past Sheep Nose and take the next right onto Nine-J Road. Follow Nine-J for 5.2 miles to where the road ends at 2 gated access roads. Park here on the left. DO NOT DRIVE OR MOUNTAIN BIKE BEYOND THIS POINT. The approach from here MUST be on foot along the left of the two access roads, following the access road past numerous homes until one reaches a sharp 90 degree turn in the road to the right. At this point, two-track continues straight on from the turn, stay on this until a climber's trail branches off to the right. This is the main access trail for Thunder Ridge, and you will follow it up toward the obvious formations that make up the area.

Where to stay

Camping is permitted along Nine-9 Road ONLY in the still forested area along the first 3 miles from the intersection with Stump Road. Please adhere to forest service signs and park and camp only in designated spots. If no camping can be found off of Nine-9, the next closest spots are to be found along CR-51 on the aproach to Turkey Rocks.


Thunder Ridge was developed in the South Platte way - a ground-up ethic that only called for placing bolts when natural protection wasn't an option. Expect mixed pro routes that are fun, challenging and tailored to folks who don't feel that a bolt is needed every 2 meters.
