About Ao Lo Dalam#

Ao Lo Dalam (often spelled Ao Loh Dalum) is a sheltered bay on the western shore of Ko Phi Phi Don in southern Thailand. The bay forms a curved sandy beach backed by steep vegetated slopes and is separated from the island’s main harbor by a low headland. It is commonly used for swimming, snorkeling, and short beach visits from longtail boats. The bay lies close to the main village area and the island viewpoint that looks over both Loh Dalum and Ton Sai bays.

Water activities: Shallow, sheltered waters make the bay suitable for swimming and snorkeling in calm conditions.
Nearby viewpoint: The bay sits adjacent to the island’s main settlement and is visible from the island viewpoint that overlooks both bays.

How to Get to Ao Lo Dalam#

Access typically requires a boat from larger piers on the island or from nearby Phi Phi or Krabi if coming from farther afield. Some bays are reachable by a short walk from coastal roads, though routes can be steep and unpaved. Check local tour operators for reliable transport options.

Tips for Visiting Ao Lo Dalam#

If visiting by boat, check tides and local weather - the Andaman waters can change quickly.
Bring a waterproof flashlight for exploring shallow caves and overhangs along the shoreline.
