Sunspot Hwy to Rio Peñasco Rd., past the pavement onto dirt road for about 2 miles before coming to the trailhead/bathrooms on your right. No overnight camping at the trailhead but overnight camping is allowed beyond that point, along the creek. Very quiet and private, a bit of snow was still down at the end of March, no other campers. Very windy, so campfires are allowed but need to be well controlled. Great spot all-around. There is NO Verizon service there or on the way in, pretty much since you pass Haynes Canyon on Sunspot.
