Labyrinth - Rarotonga

Muelle Minka Mar is one of our favourite dives near Lima, especially for those who appreciate the smaller, stranger things. Forget vibrant coral, this site is all about the macro and the muck. We’re talking a sandy bottom, scattered with broken shells, but that's precisely what makes it fascinating. The pilings of the old dock create a kind of artificial reef, drawing in an impressive collection of critters. Visibility averages around 5 meters, sometimes less, so it’s not for divers who need sweeping vistas. Instead, you'll want to slow right down, maybe even bring a magnifying glass if you could. We’ve spent entire dives here meticulously searching for barred pipefish, their tiny bodies camouflaged against the seabed. Look under every rock and shell for Pacific speckled crabs – they’re shy, but plentiful. You’ll spot blennies popping their heads out of holes, and if you’re lucky, a Pacific cornetfish might glide by, almost invisible against the murky background. This is a site for patient, observant divers who love a good treasure hunt, and it’s surprisingly good for night dives too, when many of these creatures become more active.
