A compelling journey to the depths of hell--or the end of Oregon--depending on how you want to look at it. This ride takes you right into the heart of Hells Canyon to where the road ends at Dug Bar. Do it as an out and back and gain 10,000 ft of climbing. The road is going to be much more enjoyable on a bike compared to a car, except that you should fill all your pockets with patch kits and puncture sealant to take care of the goatheads that abound.
Imnaha offers a magnificently beautiful bike climb on a gravel road into Hells Canyon Recreation Area. The road is in good shape, albeit narrow and not recommended for trailers, but who cares when you are on the narrow tires of a cylocross bike. The road eventually terminates near the Hat Point Lookout, so don't worry about trying to make a loop of it unless you're on a mountain bike. You can also ignore the warnings to stop and cool your brakes on the way down.
