Fodor's Expert Review Signal Hill
Saguaro National Park
Family
The most impressive petroglyphs, and the only ones with explanatory signs, are on the Bajada Loop Drive in Saguaro West. An easy five-minute stroll from the signposted parking area takes you to one of the largest concentrations of rock carvings in the Southwest. You'll have a close-up view of the designs left by the Hohokam people between AD 900 and 1200, including large spirals some believe are astronomical markers.
