Small boat access: From Colonial Crk CG, go 5 mi to E end Diable Lk, portage around Ross Dam over 1 mi gravel rd (60-ft elev gain), then boat 25 mi N on Ross Lk. Entr. on rt. Road access from Hope, BC: Go 39 mi S on narrow, gravel Silver Skagit Rd.
Nice boat launch. Make sure you have a spare tire for the long gravel road.
Used to be an awesome camp. Nowadays huge campers (families with kids) take all the best spots near the lake and hog it for the whole summer. They also call US rangers if you try to have any sort of fun there (since it is on US soil).
Sleep like a baby in complete silence, hike up to a alpine lake and swim in it alone. The lake has dried up and so have the people, it's empty of humans! Park ranger is there if u need him, and he was very polite and professional. Place is immaculate, no litter anywhere. Much better than the Canadian side.
Free, first-come first-serve, not busy, near a nice lake, and far away from civilization. There are pit toilets and ground water taps. Highly recommended.
