Use sunset as your turnaround alarm.
Nineteen numbered posts run the length of this trail, and there is a printed guide at the kiosk that explains what each one is looking at. That turns a 45 minute walk into something closer to a lesson, which is why it works so well with kids who are old enough to read. You start on the paved Whiptail path, cut through a rock passage with walls streaked in lichen, moss and desert varnish, and come back along sandstone ledges. Wear shoes with grip; parts of it are uneven rock.

Heat note: desert country - in summer start at dawn and carry more water than feels reasonable.
Water bottle, sunscreen, hat, snacks, comfortable shoes.
