To find the start of this trail, follow the jeep road west, and almost immediately you'll see a road to your left. Continue straight west for 1.1 miles and you'll see a large Forest Service sign with a map of your trip. This is where your singletrack starts.
Take a left on the singletrack, and you'll quickly gain just over 500 feet in 1.6 miles. The trail now drops down the west side of the ridge, and this is where the technical section starts, so be careful. Continue for 1.8 miles where you'll encounter a singletrack coming in from your right. This singletrack takes you to the Peter Grubb on the Pacific Crest Trail (no bikes). This is a good shelter to know about if you get stuck up here in bad weather.
Continue for 1 mile and you'll come to another fork in the trail. If you take a left, you can ride to Sand Ridge Lake, which is only 1/4 mile off of your path, and worth the view. Retrace your path, and take a left at the fork in the trail. Continue for 3.2 miles and you'll cross directly over a jeep road.
Continue over the jeep road, and the trail continues past Hole in the Ground Lake which you'll never see, and to my knowledge, has no trail to it. Anyway, continue on the singletrack for .8 miles where you'll again come to a fork in the trail.
If you take a right, you'll travel .1 miles to Lower Lola Montez Lake. This is a great spot to take a break before competing your loop.
