Chek is the main crag in the Cheakamus Canyon area. Others nearby include the Rogues Gallery, The Gym, The Rehabilitation Area, etc.
Chek has a lot going for it: - Canada's hardest sport climbs (up to 5.14c) - a lot of climbs in the each of the 5.11, 5.12 and 5.13 grades - enough 5.9 and 5.10 sport climbs to make the area non-exclusive - close to the road, but with good parking and shielded from road noise - a port-a-potty (thanks to the BC Climber's Access Society)
Drive north from Squamish on Highway 99 about 25 km and turn right on to the Conroy Creek Forest Service Road. This steep gravel road has been graded recently (spring 2007) and most cars shouldn't have too much trouble getting right to the large upper parking lot. However, if the road has deteriorated by the time you get there, or have a finicky car, you can park at the bottom of the hill where there's room for six or seven cars. Or you can go partway up the hill to a recently built intermediate lot (this is where the port-a-potty) is located.
From the upper parking lot you can see the sub areas of Conroy's Castle on the north side of the road, the Forgotten Wall along the west edge of the lot, and the Foundation Wall to the south of the parking lot. Most of the other cliffs are located along a trail heading south from the lot.
