Ao Nang Tower

A limestone spire rising straight out of the Andaman, Ao Nang Tower is the sea stack you spot between Ao Nang and Railay as longtails buzz past. Up close it’s wild: orange-and-grey rock veined with tufas, the slap of small waves against the base, swifts circling the upper walls, and flat turquoise water when the sea is calm. Climbers come for bolted multi‑pitch routes and outrageous views. Expect steep pockets, stalactites and airy belays that open up 360° panoramas over Railay, Phra Nang, Poda and Chicken Island. On calm days and a good high tide, the seaward side also works for deep‑water solo — scrambling up from the boat and splashing out when you’re done. If you’re new to the area, book a local guide or join a DWS trip from Ao Nang or Tonsai; they’ll time the tides and the shade and handle the boat. Logistics are simple: charter a longtail from Ao Nang Beach or Railay West (most boatmen know the tower) or paddle a sea kayak if conditions are mellow. Plan 3–5 hours, bring plenty of water, reef‑safe sunscreen, and a dry bag. Mornings mean cooler rock and lighter winds; afternoons can get choppy. In rough seas, give it a miss — there’s nowhere to land when the swell is up.
