Ao Thian Ok (Ko Tao)

Ao Thian Ok (also known as Shark Bay / Rocky Bay) is a small, private-feeling bay on Ko Tao with shallow, mostly flat water over sand and a coral-lined bottom. Water is described as clear, with the riding area ranging from shallow inside the bay to deeper water beyond the coral fringe (important for foils). For kitesurfing, SE, SSE, and S winds are the key directions, and the spot is generally best from January through April (with additional favorable months noted in November–December as well). Typical wind strength is described around 10–18 knots. Because the launch area is narrow and restricted (including resort sunbeds/trees and a very small beach footprint), the spot is more technical and is best approached by riders who can manage shallow-water entry/exit and a complex bottom. Safety is a major theme here: sources repeatedly note jellyfish, shallow coral/rocks, and moored boats in the bay. Blacktip reef sharks are also noted as a common presence under the “Shark Bay” name. Booties are recommended to protect against coral and sea urchins, and riders should be especially mindful of snorkelers/swimmers near the resort areas. Lifeguard presence and spot-specific rescue availability are reported as none/no dedicated rescue. Access is typically through resort-managed entry to the private beach area, and a 100 THB entry fee is specifically noted; sources also mention that there is no “free water” included with that entry. Overall, it’s a low-profile destination that can be excellent when the seasonal wind aligns, but it demands careful planning for launchability and marine hazards.
