you go over the divide down the hill about 2 km there will be a kiosk on your right or west this is the trail head it is a very easy trail in the summer make sure you check out Chrystal falls on the way there is a sign have fun .
You will love the views and the ride, but bring warm clothing it sometimes snows up there in July & Aug. The kiost should have a brochure with a map of the area or get one from SRD . Also should check out Ruby falls as well (budget a day round trip for this one).
