"The great Colorado River traverses several states — Colorado, Utah, Arizona, and California — and while you could technically float the entire way, you'd need some serious paddling skills and a surefire plan to do so. To get a taste of the Colorado, head to Arizona and run the relatively mild 15-mile section of the river from Glen Canyon to Lees Ferry. And don't forget to look up, so you get the full effect of the red-rock canyon walls and near-constant bluebird skies. You don't need a permit to float to Lees Ferry, but if you want to continue on, you'll need to secure one." - Travel + Leisure Editors
