The trail can be accessed from the bottom of Three Sisters, B. Line, Sandy Bowl, or near the end of Dizzy. There are two ways up. The original Ambulance Climb is following the old doubletrack road. The new improvement is a twisting singletrack route that crosses the doubletrack in a few spots. Either way takes you to the top, where you'll find the start of many downhill trails.
