My son and I drove up to Rustler Park to access the Crest Trail Loop. The drive up on the 15 mile gravel/dirt road was beautiful to say the least. There are pit toilets at the trailhead which is really convenient. The trail itself is really cool. Great views on both sides of the mountain. It's not really tough at all except for one small area when hiking clockwise around the loop at the very end before meeting up with the trail leading back to Rustler Park.
