Hovenweep National Monument
The best place in southeast Utah to see ancient tower ruins dotting the scenic cliffs, if you're headed south from Canyonlands and have an interest in Ancestral Puebloan culture, a visit to this monument is a must. Park rangers strongly advise following printed maps and signs from U.S. 191 near Blanding, Utah, or County Road G from Cortez, Colorado; GPS is not reliable here. Once you arrive, you'll find unusual tower structures (which may have been used for astronomical observation) and ancient dwellings.
