Mckena Landing quickly became our favorite beach in Maui this past May. On the remote southern end of the island, Mckena is south of Kihei. Its a small quiet beach and despite what some websites say, we found some great snorkeling there. Although you do need go out a bit to the edge of the cove to find anything. We discovered more sea turtles in this area than any of the other beaches we visited.
Mckena Landing is also a great kayak spot. We rented kayaks in Kihei, put them on top of the Jeep and took our own kayak trip in Mckena. This spot is a bit off the beaten path, and doesn't have any amenities which may be why it stays empty. So shhhh! Don't tell anyone!
