I love this dive spot although it is not for beginners. I dove Kahena several times over the course of a week, a few times with a guide and a few times solo. The biggest challenge for many will be getting down to the beach. There is a path over lava that leads down to the beach which is very treacherous. The surf entry is not for beginners, but those familiar with surf entries shouldn't have a problem. Conditions vary from day to day. I had to rescue a snorkeler who got caught in the surf zone. To the right is a nice little reef full of fish. I had some wonderful encounters with an octopus here. To the left out towards the point is the drop off. There are reports of a large Tiger who cruises the ledge but I never saw him. On Sunday's this beach is crowded, but each time we dove, regardless of the day, we were the only divers there.
