Description Suggest change

Catslab is a popular near-roadside crag with a preponderance of lower end difficulty, bolt protected slab routes; however, there are a few harder routes and some that use gear. Be careful with rope lengths as some have come to find their rope a bit short and have sustained injuries and more. The crag can get quite warm in the sun. The belay areas can be a bit crowded.

If Catslab is crowded head over to Cats vs Dogs Wall which is a five minute walk. It has a similar selection of moderates on good rock.

This crag has had its share of access issues.

Getting There Suggest change

The Catslab is about 11 miles up the canyon. Take a left at the intersection for Blackhawk and going to Idaho Springs (go towards Idaho Springs). Go through the first tunnel, over the river, then immediately park, if possible, on the south side of the road. Walk back across the bridge, and then proceed about 1/4 mile south along a solid if slightly airy trail, to the slabby, south-facing face.

Per Ryan Dresser: as of 3/29/21, the main parking lot for Cat Slab by Tunnel 5 was closed for construction. The parking along the highway was also roped off with signs that read "No parking, Will Tow".

Per Ed Quesada: as of 7/6/22 - I just talked to Martha Campbell, and the parking lot and Catslab are now open.

Please be warned! The majority of climbs in this area require a 70m rope to safety reach the ground. Every year, several climbers rap off their ends or are lowered off their rope, resulting in ground fall and severe injuries. Please pay attention to the route you are on and consider closing your system for safety.

Rattlesnake warning!

Per Kelsey Tennett: a rattlesnake has been spotted on the trail in. Be careful with kids!
