Ko Jum
Island Small island with fishing villages in Phuket region
Off Krabi on the Andaman coast, Ko Jum (Koh Jum) is a low‑key island of beaches and fishing villages. Visitors seek relaxed beach stays, bungalow accommodation and fresh seafood.
Ko Jum (often written Koh Jum) is a small island in the Andaman Sea off the coast of Krabi Province in southern Thailand. The island is known for a quiet, low-key atmosphere with small villages and beachside bungalows rather than large resorts.
Beaches, informal beachfront restaurants and simple guesthouses are the most common visitor amenities, and the island is used for swimming, snorkeling close to shore and relaxed beach stays. Transport typically uses long-tail boats that connect the island with Krabi and nearby islands.
Historically the island has been a fishing and farming community; tourism developed later and remains on a smaller scale compared with nearby tourist hubs. There are no large resorts or major commercial developments dominating the island.
Ko Jum sits off the mainland coast of Krabi Province, positioned between the larger island groups of the southern Andaman Sea. Access is by boat from the Krabi coast and nearby islands.
- Access: The island is low-key and predominantly served by long-tail boats from the nearby Krabi coastline and neighbouring islands, so expect basic transport links rather than regular car ferries.
- Visitor facilities: Facilities and nightlife are limited compared with larger Andaman islands, making the island suitable for quiet beach stays and low-key accommodation options.
