"Just outside Cortez, Colorado, you’ll find Mesa Verde National Park, a world-renowned park that houses the Cliff Palace, a well-preserved Ancestral Puebloan cliff dwelling. After spending at least a day in Mesa Verde, continue north toward the Canyons of the Ancients Visitor Center & Museum, where you’ll learn about the Canyons of the Ancients National Monument, a 174,000-acre expanse with an estimated 30,000-known and unknown sites." - Travel + Leisure Editors
