For pets, most rest stops and parks allow leashed animals, but the sand dunes can be too hot for dogs in summer.

• Family Stops: The Yuma Visitor Center has a children's play area. In Fountain Hills, the Four Peaks Park has tot lots.

These dunes stretch 40 miles and are a popular off-road vehicle area. Farther east, the Yuma Proving Ground and the Colorado River create a lush riparian corridor.
