One of the few paths that is not steep in in Arizona’s Havasu Canyon, an offshoot of Grand Canyon National Park but on lands administered by the Havasupai Indian Tribe.
There are no roads to, or drivable overlooks of, the spectacular waterfalls in the canyon, but hikers with tribal permits may make the steep, draining 20-mile round-trip slog as the crow flies — a zig-zag 30 miles of actual footsteps.
