One of the best tours we've taken! This tour takes you from river level in Moab to the top of the mesa in Island in the Sky. Areas that are inaccessible except by 4X4 really bring the park alive. During the half-day tour we learned about petroglyphs, uranium and potash mining, geology,and saw the beautiful scenery of Canyonlands close-up. Our guide Blaine (one of their few year-round guides) was outstanding! He was a font of knowledge about the park and its history, he was personable and entertaining, mindful of our safety (a must in a park without guardrails for 500 foot drop-offs), and an excellent 4X4 driver. The trusty Toyota 4X4's are well-maintained and comfortable -- although expect to be jostled since you are in rugged terrain. We visited in mid-October, which is ideal since the temperatures were very pleasant.
