Fodor's Expert Review Park Boulevard
If you have time only for a short visit, driving Park Boulevard is your best choice. Traversing the most scenic portions of Joshua Tree, this well-paved road connects the north and west entrances in the park's high desert section. Along with some sweeping desert views, you'll see jumbles of splendid boulder formations, stands of Joshua trees, and Hidden Valley and Barker Dam, remnants of the area's wild and woolly past. From the Oasis Visitor Center, drive south. After about 5 miles, the road forks; turn right and head west toward Jumbo Rocks (clearly marked with a road sign).
