I dove Makena several times last year, and this year got in at Five Caves/Graves. It's great to avoid the surface swim from Makena, to see the caves, and the visibility is better from the beginning due to no sand bottom. If you wait for good surf days, the entry is only slightly difficult. When the waves are coming in, go around the corner to Makena Landing. Loved the topography and turtles. The caves (actually caverns) are easy to view from the entrance, but bring a light to spot turtles and sharks catching a siesta. We dove this site several times over Christmas. Lots of eels and several juvenile wrasse sightings that were fun. It's worth the short walk and sometimes interesting entry.
