Rainbow Mountain

Rainbow Mountain, just west of Whistler, is an excellent year round destination. Access is usually up 21 mile creek on a good trail that starts on Alta Lake Road and goes past Rainbow Lake.

The peak is best reached from the west, in winter or in summer. There are a variety of routes from this side, but all are easy scrambles. There's no real trail though, so you are on your own for routefinding once past Rainbow Lake. The climb to the summit is a long day trip in spring or summer, but usually takes 2 days mid winter.

21 mile creek is the drinking water supply for Whistler. Camping in the watershed is not permitted, although it is usually tolerated in the winter when fewer people visit the area. Good spots for summer camping are at hanging lake (official campground) or at beverly lake further north.
