Havasu Falls can only be reached by hiking 10 miles - one way.

If you take a raft trip down the Colorado River through the Grand Canyon you can see other lovely falls. We did it on a 9-day trip. Awesome experience.
We've been to the South Rim and enjoy it (off season) but we really like the North Rim for the cooler temps and because it's low-key and less crowded. DeMotte national forest campground is the place to be toward the end of Sept. The fall color of the aspens are gorgeous. Just south of the campground are wonderful places to boondock and you only have to drive 1/2 miles or so on a flat, well-maintained gravel road to start finding spots. Of course, you can stay in the park itself, also.
