Though a long drive from Seattle, the rewards are great here. We snowshoed along Highway 20 out of Mazama with the intent to camp at the Washington Pass Overlook. Highway 20 is blocked a few miles west of Mazama, and one must travel approximately 8 miles over snow to the overlook. The only negative part is dealing with all the snowmobilers who seem to enjoy buzzing the hikers and skiers. However, if you're able to look beyond that, the hiking is mellow and the views of Silver Star, the Wine Spires, South and North Early Winters Spires, Liberty Bell, etc. are awesome. One could easily spend a week back in here exploring side drainages, skiing couloirs, or making rare winter ascents on some of the surrounding peaks. A barred owl kept us company at night, and the morning brought 4 inches of fresh snow. A ""thru-hike"" to Newhalem is definitely in order. I can't wait to return.
A word of caution: this route crosses several avalanche chutes.
Happily, there is no sno-park permit required to park at the road end.
Check out the brewery in Twisp for some absolutely amazing food and friendly service. Ditto for breakfast at the ""hip"" shop in Mazama.
