If there's one place in our travels that has seemed a nearly hidden gem -- a place where hardly anyone goes, yet is full of incredible beauty -- it's the confluence of the northern tip of Grand Canyon National Park, where miles of the Colorado River are protected before they enter the canyon, and the southern tip of the Glen Canyon National Recreation Area. It's a serene place called Lee's Ferry, where the Colorado gently winds through vermillion cliffs. Rafters hit the first rapid here to begin the 88-mile journey to Phantom Ranch, the historic camping oasis nestled nearly a mile below the rim of the Grand Canyon. Wild horses roam the hills and can be spotted frolicking in the riverbed.

But alongside the glorious beauty of the red rock set against the dark river and blue skies, long before it was the launching point for Grand Canyon rafters this historic place was the gateway to Arizona. It's the only place along the river for 700 miles that the riverbanks are directly accessible by land, making it an ideal crossing point, and today, the only place where you can get down into the deep cuts of the Colorado without hiking in.
