Koh Jum and Koh Siboya are two neighbouring islands located between Krabi Town and Koh Lanta. They are actually very close to the Krabi mainland (they are located a few kilometres south of Krabi Town) but for some reason, they are quite difficult to get to – especially out of season.
There are basic passenger and motorcycle ferry services from the pier at Laem Kruat to the villages of Ko Jum and Ko Pu on Jum Island; as well as to Ko Siboya village. Service is sporadic and the last boat leaves at around 3pm. You can also take a boat from Laem Hin pier at the end of Had Yao (Long Beach) to Ko Siboya only; the last boat leaves around 6pm from here.
To get to either of these mainland piers you will need to take a local bus or taxi from Krabi Town; it is a journey of around 40km, going via Neua Klong town (no need to change buses).
A much easier route to Koh Jum available during November to April only is direct from Krabi Town, on the big passenger ferry to Ko Lanta. The boats stop offshore and the resorts send longtail boats to collect alighting passengers. They also stop on the way back from Ko Lanta to Krabi Town. Ko Lanta ferry schedules >>
Once on the island, you can rent a motorbike or bicycle, or simply get around on foot. Longtail boats are available for charter for fishing or island-hopping, it is best to ask in your resort for the best deals.
