Thailand's marine national parks (all ~22–26 parks under the Marine National Park Division)

Spearfishing and all fishing are prohibited inside every marine national park in Thailand (e.g. Mu Ko Ang Thong, Hat Noppharat Thara–Mu Ko Phi Phi, Mu Ko Lanta, Tarutao, Mu Ko Chang). Boundaries can be difficult to identify on the water; divers must research locally.
