Hole In The Ground features 17 miles of hiking trails near Truckee, CA.
Exit Interstate 80 at Soda Springs. From the off-ramp, turn left (north) and then make a quick right after the underpass. Look for a sign board on the left side of the street where a trail intersects this road. This is the END of the ride. To avoid a few miles of road riding, shuttle a car to the Boreal Exit. Park on the road to the north of the freeway.
