Khao Lak Lam Ru National Park

If you want “green plus sea” without a long expedition, this park delivers. You can walk short forest trails that open onto rocky shoreline viewpoints, then cool off on small sheltered beaches. Inland, waterfalls and jungle paths give you that humid rainforest feeling, with plenty of shade. It’s a solid day trip from Phuket if you want nature that feels active but still easy.
