Ko Thap (Thai: เกาะทับ, "Thap Island", sometimes spelled Tub[citation needed]) is an island in Krabi Province, Thailand.

Locals refer to Tab Island as Koh Tub.

[1] Aside from having beaches, a coral reef surrounds the area, which has attracted snorkeling and other outdoor activities.

Tourists can walk across the beach to all of the islands.
