Description

This is the collection of boulders in the creek and the woods across St. Vrain Dr from The Monkey Skull and less than a half mile westward past Central Gulch. A few well known hard lines live in this area (e.g., The Hatchet, Vacation), but there are several fun easy and moderate problems as well.

Getting There

Park at the clear pullout on the south side of St. Vrain Dr. (the same parking for Monkey Skull). The boulders can be seen in the river and just through the trees across the river.
