Menara II is a boat-access wall off Una Una in the Togean Islands, with hard and soft coral, reef fish, and a cave section that divers enter one at a time. The profile is calm enough for buoyancy practice but deep enough to feel like a real wall dive, so it suits confident beginners and intermediate divers better than brand-new open-water students. On a good day you get a quiet remote-island reef with barracuda, snapper, and plenty of structure to keep the dive interesting.
