Bouldering in Squamish was limited to the Bog Wall in Murrin Park until 1996 when a group of boulderers from Victioria set up shop at the base of The Chief. They quietly started unearthing classic after classic until the secret was out. Now there are easily over 500 problems in the forest and that number keeps growing as new areas are found and developed. src
The Grand Wall Boulders is the most popular bouldering area in Squamish.
Driving North along the 99 "Sea to Sky" Highway 50kms North of Vancouver you will see The Chief as you descend into the end of Howe Sound. You can't miss it. source
They lay directly under the Grand Wall, right beside the provincial campground. (from http://www.bcclimbing.com/areas/grand-wall-boulders)
