Amazing hike. Like everyone says the book end up and downs are killer. We day hiked it so we parked down at the beach to eliminate the extra road trip to the trail head. Do not, do not follow this maps route to the falls! Once at the beach at Waimanu go past #10 campsite and follow the edge of the valley in to the falls. About a mile. It is sparsely marked with pink ribbons. Well worth the effort.
