All of the major waterfalls are along the trail between the Village and the north side of the Campground except for Beaver Falls (which is a strenuous 7 mile round trip hike with multiple creek crossings that should only be undertaken by experienced hikers during good weather).
Hiking past Beaver Falls means you will be leaving Havasupai land and will be out of range of any help or assistance - and is NOT recommended at any time.
