Dierkes Lake Climbing



If one word were used to describe the climbing at Dierkes, it would be powerful. Overhanging, super steep sport and trad and burly, big-move bouldering are the names of this climbing game. 

What Makes It Great

A short walk from the parking area, the climbing is on the north side of the lake. Most sport routes are 5.10 or harder though some sub-5.10 sport, trad and TR routes are available. For those looking to get their bouldering on, there are over a hundred established routes to choose from, Bring a partner you trust, tap into your core and pump out your shoulders and arms in this roofy, smeary, laybacky, crimpy funland.

Who is Going to Love It

Idaho’s volcanic roots created this blocky landscape that is a climber’s playground.

Directions, Parking, & Regulations

A bit of an unknown, Dierkes is off the radar compared to the Black Cliffs and the City, providing a bit more solitude than those other highly-visited areas. Near Shoshone Falls, there can be traffic coming in during the spring when the falls are running big, but the climbing is usually chill.
