The diving was great at Bunaken. Lots of turtles, we also saw sharks, and a lot of other fish and corals. The guides are great and the boat captains also. Your gear is taken care of for you - preparation and also cleaning every day. We experienced some currents, but the guides did a great job of trying to avoid the worst currents and making sure we were safe. Tip: Bring some cash to leave a tip as there's no way to get money once you are there. There are ATMs outside Manado airport.
