We drove to Waimea Canyon on top of the island of Kauai, then continued on to the end of the road. The parking area is on the rim of the caldera with the NaPali on one side and the Alakai’i Swamp on the other.   We hiked a trail along the rim of the caldera and then descended into the swamp basin.     Uluhe Ferns (Dicranopteris linearis) covered the slopes on the way down to the rainforest of the massive swamp.    The Alakai’i Swamp trail is a favorite, one we have done a few times.
