Blue Diamond features 30 miles of hiking trails near Las Vegas, NV.
Heading west on the 15 from Vegas take the Blue Diamond exit or highway 160. Just stay on the road and once you pass the turn off for Red Rock Canyon the parking lot will be on the right after a mile or two. The lot is hard to see if there are no cars in it but there is a well marked sight seeing lot on the left after another mile. If you get to the mountains you have gone to far. There is a trail map in the lot.
