North Twin Island - Mergui Archipelago

North Twin Island, twenty clicks north of its bigger sister, South Twin, is a low-key spot but often delivers some exciting encounters. We’re mostly there for South Pinnacle, a granite rock structure that starts just three metres down and bottoms out at 35. You'll often find yourself in strong currents here, but that's what brings in the bigger stuff: Zambezi sharks, rainbow runners cruising by, and eagle rays gliding through the blue. Mantas show up too, if you’re lucky. Visibility is usually top-notch, so it’s a good one for those who enjoy a bit of current and keeping an eye out for pelagics.
