    StandoutExceptional marine biodiversity

    Elephant Head Rock is a Similan classic, and for good reason. It’s a proper playground, a maze of giant granite boulders stacked on top of each other, creating tunnels and swim-throughs that just beg to be explored. We love tracing the light shafts as they cut through the water, illuminating patches of sand or a solitary sweetlips hiding in the shadows. There’s always a surprise around the next corner – a big checkerboard wrasse zipping past, or maybe a curious singular bannerfish eyeing you from an overhang. Drop down to about 20 metres and you'll often spot leopard sharks snoozing on the sand, completely unfazed by divers. We’ve found the currents here can be a bit shifty, so a good guide makes all the difference, helping you navigate the best routes through the rock formations. The deeper sections, around 25-30 metres, are where we've occasionally seen manta rays gliding by, especially between November and February when the plankton blooms. It’s an ideal spot if you enjoy navigating tricky rockscapes and seeking out big fish in the blue.
