It's not a very detailed map (I have a much bigger, very much more detailed map, but it too big to scan), but it is what I was thinking of. From Cambridge, catch hwy 71 to the Brownlee Dam. Continue on Hwy 71 North to thge Oxbow Dam. Take Hwy 86 South West to Hwy 39. Take Hwy 39 North to the Hells canyon Overlook. For the return trip, same thing ony backwards.
OR instead of crossing the Oxbow Dam, continue north along the Snake River to the Hells Canyon Dam and the Hells Canyon Visitors center.
