I can't recommend this guided hike enough. Our guide/driver, Lonnie, was fantastic! We had a blast riding in the UTV to the canyon site - just the right amount of excitement and safety. He was great with the wide range of ages on our trip (age 4 to middle age) in helping us get over the boulders and obstacles. By the time we turned back, we all felt very confident in getting over the tougher spots. I would highly recommend East Zion Adventures and this adventure in particular. We managed to have a 10 out of 10 experience and avoid the crowds that were undoubtedly mobbing the park on Memorial Day weekend. This slot canyon is absolutely stunning at every turn. Getting to careen along in the UTV (a real life roller coaster, that my boys LOVED) was a bonus!
