A group of 10 friends and I spent a 3 day weekend enjoying Ross Lake and the mountains that surround it. What a great place to explore! We rented boats from the Ross Lake Resort and used those boats to access the Desolation Peak Trail from the boat landing on Ross Lake. It's just north of Cat Island and you can look for a wooden sign that says Desolation Peak Trail. The landing area is small but there is quite a few other potential landing areas just south that you can easily bushwack up to the trail from if the landing area is full of boats (which it was during our trip). The trail overall is in good conditions, though there are about 5 small blowdowns in places along the trail. After leaving the lake I saw only one water source, a very small creek about 1/2 way up the mountain. Our group did not encounter any snow on trail whatsoever. The trail gains approximately 4,400 feet and is a hard 4.7 miles to the top. The first few miles are in the trees, though occasional openings give you a preview of the stupendous views from the top. After breaking out from the trees, you switchback up to a false summit. From the false summit, you follow the ridge before a short elevation gain to the high point and lookout tower. During our trip there were some clouds, so Baker and Shuksan were hidden but the rest of the mountains visible were simply awesome. Our group took about 3.25 hours to get to the top (with quite a few breaks, including lunch), but if you are in good shape the summit could be attained in 2 - 2.5 hours. So if you're looking for 360 degree views of wilderness, this hike is very difficult to beat!
