Bridger's Cache is located near the base of the Mary Jane ski area. Take I-70 West to the Empire/Berthoud Pass (Exit 232). After reaching the other side of Berthod Pass, you'll go about 3 miles to the turn off to Mary Jane. Stay on this road until you arrive at the base of the ski area. Turn right and you will go over the skier bridge. The Bridger's Cache entry gate will be on your right just past the skier bridge.
