Some other options might be Great Sand Dunes NP, Durango, and Mesa Verde NP. If you’ve never been there, the Durango-Silverton train ride is worth the trip. In northern AZ there’s Grand Canyon, Meteor Crater, the Sunset Crater and the Painted Desert along I-40. Then, too, the Oak Creek Canyon-Sedona area is pretty and there’s Montezuma’s Castle along I-17 to Phoenix. Too many choices for two weeks and just some suggestions to check out. There’s ample opportunity to hike around most of them. In two weeks the heat will start to relent. Nice up north, still hot in the desert but beginning to cool off at night.
