Hidden off-route spots: the Painted Rock Petroglyphs near Gila Bend, AZ, feature ancient Hohokam carvings on volcanic boulders, and the Salton Sea, a salty inland sea with bizarre shorelines and abandoned resort towns, is a surreal detour.

Entering California, the Imperial Valley's irrigated farmlands contrast sharply with the barren desert, and finally, the coastal ranges around Santa Paula offer rolling hills and oak woodlands.

In Yuma, the historic downtown features date palm farms and a thriving agricultural industry. In Santa Paula, the California Oil Museum celebrates the region's petroleum history, and the town's Main Street is lined with century-old buildings housing antique shops and diners.
