A mecca for rock climbers, kokanee salmon fishers, and narrow-gauge railroaders, all in one long string of three reservoirs. We saw the topmost level only, except where the road passed near a dam or two. We took one walk, on a trail that isn't even claimed among the 7 highlighted trails in the park, from a roadside rest area labeled "Crystal;" we think that's because the trail's viewpoints let us look a long, long way down to see Crystal Reservoir, which is one of the three in the NRA.
