Defiance Rafting delivered a fun on-the-water experience for our family of six (kids 17, 14, 11, and 10). Our guide, Greg, was very nice and engaging, and the scenery through the canyon was beautiful. The reason for 4 out of 5 really has nothing to do with Defiance. In short, if you are looking to raft in Colorado, there might be better river routes, as the Colorado River through Glenwood Canyon runs right along I-70. Again, Defiance delivered a good experience; they can’t do anything about their route. One other suggestion for visitors to Defiance: wear shoes that can get wet and have a back strap on them (i.e. not flip flops), otherwise you will have to wear their river booties (kind of gross).
