Check out Moab Utah for a canoe trip on the Green River into Canyonlands National Park and return by jetboat up the Colorado River back to Moab.
Or if you go later, outfitters raft Cataract Canyon from Moab to Lake Powell. It is a hundred mile trip containing 28 Grand Canyon style rapids. Short trips are motorized. GO 1 day in Spring, overnight, 2-3 nights camping or non-motorized trips are 5 and 6 days long. Ask Moab outfitters about a paddle option intertwined with a motorized trip and get the best of the canyon in regards to saving time with your vacation calendar and money, since it is a shorter trip than a 6 day Grand Canyon (again 6 days is a partial Grand Canyon trip.) discovermoab lists all the Moab outfitters.
