The Laam Son National Park covers 315 sq km of land shared by Ranong and Phang-Nga Provinces, it also includes around 100km of Andaman Sea coastline – the longest protected shore in the country – as well as over 20 idyllic islets. Much of the coast here is covered with mangrove swamps, home to various species of birds, fish, deer and monkeys (including crab-eating macaques), often seen while you’re driving along the road to the park headquarters.
