Coral Corner is the Mushroom Island wall off Munda, with hard and soft coral, reef fish, and regular sightings that can include nudibranch, barracuda, reef sharks, rays, turtles, and the occasional hammerhead. It is usually reached by boat from Dive Munda, and the site can feel more exposed than a lagoon stop when seas or visibility slip. Treat it as a proper wall dive with strong wildlife payoff rather than a sheltered training site.
