Warm River Campground To Tunnel
The trail from the Warm River Campground to the tunnel is a classic trip for beginners. It is an easy uphill grade. As you travel further up the canyon you steadily gain elevation above the river bed, providing a pleasing view of the canyon, the river, and the forest. In the end, you are rewarded with a fun ride threw the old rail road tunnel. For the more adventuresome cyclist, you can continue up the trail for another 50 miles if you want. Of course the ride down is a pleasant glide back to the campground.
