Fodor's Expert Review Bajada Loop Drive

This 6-mile drive winds through thick stands of saguaros and past two picnic areas and trailheads to a few short hikes, including one to a petroglyph site. Although the road is unpaved and somewhat bumpy, it's a worthwhile trade-off for access to some of the park's densest desert growth. It's one-way between Hugh Norris Trail and Golden Gate Road, so if you want to make the complete circuit, travel counterclockwise. The road is susceptible to flash floods during the monsoon season (July and August), so check road conditions at the visitor center before proceeding. This loop route is also popular among bicyclists, and dogs on leash are permitted along the road.
