We are coming to the GC in Sept and plan on hiking from South Ri to North. We were then planning on taking the shuttle back around to the South Rim. Is there a way to take a shuttle from the north rim (or from the south rim) to the trailhead for Havasu Falls? Then once we have hiked down and back, take a shuttle the next day back to our car which will be at the SOuth Rim? We will be there 4.5 days. Thanks!!
