Off the beaten path and alot of solitude...after the abandoned parking lot to the left is Mossy rocks..climb up to the caves! Chris Ahearn (1129) over 1 year ago N/A: 16 Completed 6 Reviews This trail is closed. There is no access to this trail from either the Crosscut trail head or First water trail head. Dan Robrecht (1622) about 2 years ago N/A: 49 Completed 49 Reviews Nice enough, but less interesting than many hikes in the Sups. Steve Ventre (203) over 2 years ago N/A: 8 Completed 6 Reviews The distance represented in the description is based upon leaving from the trailhead, which is no longer accessible by motor vehicle. If you being your trip from the First Water service road you will need to add a couple more miles to the overall in-and-out. Daniel Heasley (649) almost 3 years ago N/A: 17 Completed 17 Reviews Hiked trail a few times over the years, close to mom and dads house. Will hike again when I get back to visit. Suzanne Burke Bunnin about 4 years ago N/A: 3 Completed 2 Reviews This is a really nice tune up trail to do during the cooler months. Bonus - if you go after rains, there is a small waterfall. Unfortunately, you can't get right up next to the waterfall unless you bushwack.
