You will need an adventure pass from the forest service and a wilderness permit to access the San Gorgonio Wilderness area. All back packs must be tied up in trees during over night stays. There are occasional black bears in the area.
Use the map for parking and the trail entrance. Follow the trail until you see the sign for Dollar Lake. Go to the right fork. I found the hike takes around 6 to 8 hours with a heavily loaded pack.
From Dollar Lake you can take a day hike to the top of San Gorgonio, 11,400 feet!
Dollar Lake is a great day hike or
as a base camp for an assault on the peak
