A great alternative to Moon Pass Road that makes for a great loop when combined. There is good camping spots all along this road with a couple of official campgrounds down at the end. This road has less traffic than the Moon Pass Road if any. At the bottom, there is a gate that stops any traffic and from there you can take Trail 300A all the way into Avery, ID.
Unlike the Moon Pass Road, this actually does have a few hills to keep you entertained.
