This was our first trip to Maui. We stayed in the condos north of the Sheraton and simply walked right into the water. This was my favorite activity and only cost me $5.25 a day snorkel rental. We beat the crowds by enjoying the waters on the north side of the rock by the old pier. Floated around the rock to the Sheraton side and checked out 5 turtles in the channel. It was awesome until I ran into the hoards of people on the other side.
