This trail is usually open from from June until the first big storm in late October. It can access from the Thunder mountain trail head and can be looped by riding up the castle rock trail on the North side of 88. This a difficult dh that starts off with flowing single track on loose small rocks and then gets chunky and technical for the last 2/3. One of the longer and more technical downhills in the region.

 An amazing Gem of a trail. One of the most beautiful climbs I have ever done and the downhill is a hoot. Fast flowy parts through wild flowers at the top with epic views, then tons of technical rocks garden through the forest. I posted a video of the trail in the VIDEO TAB. This is probably my favorite ride in the Kirkwood area. I found this more fun than the Silver Fork DH trail but the rocks gardens slightly easier than Silver Fork DH.

 This ride is definitely better done by riding up Castle Rock and then up Thunder Mountain to the top and then back down. Can do the last .5 miles as a hike or a bike. The Thunder Mountain DH section of the loop is chewed up. It looks like it gets a lot of horse use so there are lots of loose rocks in-between the larger rock drops. Disappointing but we'll definitely do it the other way some time.
