Notch Lake is a beautiful area away from the crowds on the Good Medicine Wall. It requires a longer approach but you will be rewarded with lakeside climbing on the getaway wall in an amazing alpine setting.
The Notch Lake trail starts off of Highway 150 just past Mile Marker 29 if you are coming from Kamas (northbound) at the "Bald Mountain Trailhead." There is ample parking and a pit toilet at the trailhead. Basically follow the trail toward Bald Mountain for a short way and then go left when the trail forks (there isn't a sign for Notch Lake but the fork is obvious). Hike this for about 2.3 miles to the lake.
Try the DWS along the west side of the lake. From the routes traverse right along a large ledge making a couple of scramble moves to get started. Keep traversing along the bottom of the wall, V1, with many 15'-25' exits. Some large loose rocks about 3/4 way along the traverse make it interesting but over all the rock is good quality. Enough fun to leave the rest of the climbing gear and just bring the shoes, chalk bag and a towel.
