This is the easiest way to the Thunder Mtn Dh. It is a beautiful climb with amazing 360 views most of the way. It isn't overly long but it expect at about an hour to get to the top. There are some exposed sections of the trail and the last 1/8 mile is a steep section that is a hike a bike for most all riders.

       This is one of the most beautiful climbs I have done to date. Just gorgeous. Climbed this trail up to Thunder Mtn DH in July. Beautiful wild flowers, vistas all around. The last bit of the climb is hike a bike it has lots of loose rocks and is steep. Highly recommend.
