From Evergreen Trail Guide
This is a short (6 miles to the pass), challenging, views galore trail right near Washington Pass. Makes for a great half day ride.
How to find it
From a post on MTBR: From I-5, Head east on SR20 towards Winthrop. After Washington & Rainy Pass, around MP167, cutthroat lake/pass is on the north side. There's pretty decent camping right across the road at lone pine (or fir?) campground.
Park in the Cutthroat Trailhead parking lot. Turn about 4 miles east of Washington Pass on the well signed paved road to the parking lot (1 mile).
Typical east side conditions. Expect a dusty trail to the lake and progressively rockier, less dusty and more technical as you climb. You will climb to approx. 6,800 feet so be aware of weather changes and snow levels. Expect wind at the pass.
Trail is in good shape but quite rocky in places, dusty to the lake.Jackd49 09:32, 12 August 2009 (PDT)
From the parking lot the trail gradually climbs to the lake in 2 miles. Go left if you wish to descend to the lake or go right to go to the pass. From here the trail gets steeper and more rocky. Cross a few easy creeks and begin the big switchbacks finally ending on a long switchback to the pass. (about 4 miles from the lake). Remember that this is the upper limit for bikes. The trail continues down to Rainy Pass (no bikes) or across the Pacific Crest Trail (no bikes). It is worth it to drop the bikes here and hike up either sidehill for stunning views (Silver Star Peak and Kangaroo Ridge especially prominent). When you have had enough, turn around and enjoy the fast challenging ride back to the car.
Local Points of Interest
Lone Fir Campground(Pit toilets, water) is about 3 miles east of the trailhead. A nice place to camp. You are "allowed" to camp overnight at the trailhead - no water no services - tear the tent down in the morning etc.
This is a multiuse trail. Expect to see hikers and horses.
This is for information about the trail's history with respect to mountain biking, the land owner, etc.
