    StandoutExceptional marine biodiversity

    Gamat Bay is one of those spots we always try to squeeze in, especially if we’re over on Nusa Penida for a few days. It's a small, protected bay, which often means an easier start before you drift out onto the slope. The real draw here is the sheer density of coral, particularly those sprawling staghorn formations in the shallows. You could spend half your dive just poking around the nooks and crannies there. As you head deeper, the slope drops away pretty dramatically to around 23m before disappearing into the blue. We've often seen whitetip reef sharks cruising the edge where the light starts to fade, and if you’re lucky, a marble ray might glide by. Keep an eye out for the smaller stuff too, like the freckled anglerfish we spotted once, perfectly camouflaged on a sponge, or the electric flash of a blue ribbon eel. For sunfish seekers, July to October is your window. The currents can pick up here, pulling you around the corner towards Toyapakeh, so it’s best for divers comfortable with a drift.
