Khao Khian

Khao Khian (เขาเขียน) is the best-known prehistoric rock-art cliff in Phang Nga Bay — a shore-notched limestone face on the boat road toward Koh Panyi, inside Ao Phang Nga National Park. Red, yellow, and orange pigments form people, fish, birds, and other figures that Fine Arts Department work has long dated to roughly three millennia or more, widely interpreted as marks left by seafarers sheltering along this coast.

Boats approach the eastern overhang so the panels sit just above the tide line in good light. Morning passages are often clearer for photos. There is no beach resort here and no need for hiking kit — binoculars or a camera with modest zoom help more than walking shoes.

Watch out: These are fragile archaeological surfaces. Do not touch, wet, or “enhance” the paintings. Follow guide and park instructions if any landing is offered; most visitors never leave the boat.

Fees sit inside the usual national-park tour package — confirm with your operator. Pair with James Bond Island and Koh Panak for a full bay day, or stay land-based in Phang Nga town for caves at Tham Phung Chang.

Insider Tip: Ask the boat captain to pass the east face when the sun still rakes sideways across the pigment — midday overhead light flattens the reds.
