Hells Canyon Dam sits at the end of the road. Literally. It's the last of a series of dams that pen up the Snake River as it rolls along a steep, deep crevasse that separates Oregon and Idaho. To access the dam, you pick up Hells Canyon Road at Copperfield (if coming from the Oregon side) and snake your way up along the Hells Canyon Reservoir for about half an hour. It's a scenic drive that offers plenty of places to pull off and swim, and quite a few trailheads for hikes up into the Idaho side of the canyon. The route takes you along the base of some very steep cliffs and overhangs, and you can tell by the dents in the blacktop that there are often rockfalls along here. My wife was white-knuckling it during most of the ride out.
The dam itself is nothing too spectacular, but it does sit in a very scenic spot on the river. Once you cross the dam, the road ends in a boat launch, and this is where the adventure begins. Here you can put in for kayaking, rafting and drift-boat floats down the canyon. Fishing abounds. The dam itself has a little visitor's center with historical photographs and a couple of Idaho Power employees who can answer questions. We were able to get some good info on road quality for our forthcoming drive up the forest service roads into the Wallowas. Super helpful!
If you're not floating or fishing or otherwise using the recreation side of the river, there's not a whole lot to do here other than learn about the dam and take in some pretty scenic views from the canyon floor. It's almost more about the views on the drive in. And you'll be seeing them again on the drive out, as there's nowhere to go from here but back the way you came. read more
