Why should you go there and how do you do it right?

Visit the Phraya Nakhon Cave, the collapsed cave with a royal pavilion beneath a natural skylight, and be aware that everyone else will want to see the same thing. In the late morning, the light streams through the opening in the roof, creating the mesmerizing play of light you've seen in the photos. The route there involves a steep climb, mostly on stairs, either after a short walk or a boat ride to the beach. Take the boat if you'd rather do some climbing than twice, and bring sandals, as you'll need to wade through some water to board.

Don't miss the Sai Cave on your way. The climb is short, steep, and takes about twenty minutes. Afterward, it's much quieter. Beyond the caves, the park stretches across 98 square kilometers with limestone hills, mangrove boardwalks, freshwater marshes, and beaches. Twelve marked areas are included in the 200 baht entrance fee. The lotus blossom season is particularly recommended. Boat trips through the wetlands are also available.
