Ao Chalok Beach

Koh Tao is reached by daily ferry from Chumphon — the crossing takes about 120 minutes. Once on the island, the beach is a 15-minute drive from Mae Haad pier. Free informal roadside parking is available near the beach, so arriving by songthaew or rented scooter is easy. There is no entry fee.

The bay's multiple dive schools make this one of the easiest places on the island to get certified or log a fun dive — just walk the pier line and compare what's on offer. When you need a break from the water, the short hike to John-Suwan Viewpoint (about 1 km away) delivers a sweeping panorama over the entire bay. Ao Thian Ok, known locally as Shark Bay, is 1.5 km away and famous for blacktip reef shark sightings in the shallows — worth the short trip. Ko Nang Yuan, three islets connected by sand causeways, is 7 km out and a classic Koh Tao day excursion.

Tropicana and The Tropicana Restaurant are both within 200 metres of the sand and cover the basics well. The Happy Monk Bar & Restaurant, also 100 metres away, mixes Thai and Western menus — handy after a long dive day. Big Bite and Sky Light round out the immediate strip if you want to graze along the beachfront.

Buddha View Dive Resort and Assava Dive Resort sit right on the beach, making pre-dawn dive departures effortless. Carabao Dive Resort and Hydronauts Diving Resort are 100 metres away, and Koh Tao Tropicana Resort is 200 metres out — all close enough to hear the water from your room.

Shoot from the eastern headland at sunrise for the full curved arc of white sand with the blue bay glowing in low light. The dive-school piers make strong foreground geometry at golden hour, especially when boats are moored and the water is still.

October and November bring the northeast monsoon: expect debris on the sand and reduced visibility in the water, though the sheltered bay stays swimmable. Avoid those two months if you want the beach at its best. The dive-school piers are active early in the morning, so give way to equipment trolleys and student groups near the water's edge. The beach approach is relatively flat, but the sand surface limits wheelchair mobility.
