A fishy Bunaken wall known for big schools and resident napoleon wrasse.
Mandolin is one of Bunaken's busier walls in terms of fish life. The structure is the classic Bunaken profile, a shallow coral shelf that breaks into a steep drop, but Mandolin tends to hold more fish than its neighbors.
Divers come for the schooling action: a resident group of midnight snapper, clouds of fusiliers and surgeonfish, and large napoleon wrasse that cruise the shallows. The wall carries big sponges, sea fans, and black coral, and turtles turn up here too.
It works as a relaxed drift along the reef. The shallow top at the end of the dive is bright and full of life, which makes for an easy safety stop and a good spot to burn off remaining air.
Getting there
Mandolin is on Bunaken island and reached by dive boat from Manado in roughly 45 minutes to an hour. Operators slot it into day trips alongside Lekuan and other walls, and most run it as a guided drift dive. The marine park e-ticket is required.
Best time
Conditions are good most of the year, with the dry season (April to November) generally calmer and clearer. The shallow reef is bright on a sunny, slack-tide morning when the schools sit up shallow.
Good to know
Spend time in the shallows at the end, since the fish density up top is often the highlight. Keep good buoyancy off the wall and the reef, and let the napoleon wrasse approach on their own rather than swimming at them.
Both are walls, but Mandolin is known for heavier fish life, including schooling midnight snapper and resident napoleon wrasse. Lekuan is more about the turtles and the sheer drop.
It can be, in calm conditions. It is still a wall with some drift, so reasonable buoyancy helps, and a guide will pitch the dive to your level.
You can snorkel the shallow reef top, which is colorful and full of fish, but the wall and deeper schools really need scuba to appreciate.
