After spending the night in Flagstaff, the trek continued. Checked out of the motel, got on to I-40, and then three miles down the road got off I-40. Walnut Canyon has to be one of the easiest parks in the National Parks system to visit: conveniently close to Flagstaff and with a dedicated freeway exit.
Following establishment of the the Civilian Conservation Corps, CCC workers developed the Island Trail, a trail that includes multiple flights of stairs and allows visitors to walk down into the canyon and see the cliff dwellings from a closer perspective. It's not a particularly difficult trail, but, wow, after a while you start to hope you've seen that last flight of stairs. And then it hits you -- all those stairs you've come down require you going back up eventually. Anyone with bad knees or a weak heart should probably limit their views of the cliff dwellings to what they can see from the rim.
