The Canyon Block is an obscure, house-sized, 35-foot tall boulder of high quality granite perched high on the North side of Boulder Canyon. Since its walls are South facing, this is a great place to go when it's cloudy, or cold.

The majority of the climbing is low angle and follows natural weaknesses like cracks, seams, and flakes. Most of the harder routes rely on a mixture of pitons, bolts, and traditional gear. None of the routes have fixed anchors, but the top of the block has plenty of trees, and cracks to set up anchors. For those interested in toproping, the top is easily accessed by hiking to the North side.

Getting There 

From the bridge at the bottom of Boulder Canyon, drive 4.7 miles and park at an obvious pullout on the North side of the road next to a large orange, red, and yellow sign that warns people to be careful with matches and fire.

Follow a gully with some exposed water polished granite slabs, and at the top bear right out of the gully and work your way slightly up and left towards the Canyon Block which sits at the top of the hill hidden by some trees.

The entire approach shouldn't take more than 20 minutes.

The crux is gaining a thin crack about 30 feet up, a hard mantle tries to keep you from the crack. Really good route. ...[more]   Browse More Classics in CO
