There is a great wealth of climbing and bouldering opportunities in Squamish suitable for everyone, from beginner to expert. The rock in Squamish is granite and most of the climbing locations are in wooded areas, providing shelter from the hot sun during the summer months. On the flipside it can take a while for the rocks to dry again after rain.
The book Squamish Bouldering by Marc Bourdon and Scott Tasaka describes all the different climbing locations and routes and can help you get the most out of your climbing experience in Squamish and the surrounding area.
