The most awesome trail. Definately worth the drive. A long climb at first up a dirt road. Be careful on the beginning of the downhill - it gets a bit rocky and friends have been known to spill blood if going for too much air. The singletrack after this is smooth and sweet through the trees.
How to get there:
Take I-10 to Benson and go south on Highway 90, stay on that and it'll turn into Highway 92, take that south until you get semi close to the mountains (the Huachuacas) and take Ramson Canyon Road west (be careful you don't miss it). Take the first dirt road on the right, it'll be a little parking lot and you'll see the end of the trail. Ride up Ramsey canyon road (the pavement) until you get to the brown canyon sign on the right and a cattle guard. Stay to the left up the dirt roads. Once on the single track Stay to the right. Props to those who make it all the way up the single track towards the end. Enjoy the view!
