Viking Cave (★4.6)

Viking Cave has a striking bay and a beautiful cave above the water, but the real deal is underwater a few hundred meters to the north of Viking Cave. A few years ago, the Phuket Marine Conservation department put down a beautiful artificial reef to re-establish marine life after the tsunami.
