I really couldn't find the trail. There are trails all over and none are marked. I just wandered around 3 or 4 of them. It's a beautiful area but very sandy. Made it a little difficult on the steep parts. I would recommend getting info from someone who has done it before for finding the actual trail head. Still had a great day and beautiful views.
