The cave fascinated Thai Kings for many generations. A few of them visited the cave and left their signatures on the wall. The cave has a semi-open roof, allowing some light to pass through, forming an ethereal image where the pavilion seems to glimmer. You might be spending a couple of hours here because hiking over 2 hills is involved. You could choose to hike both, or take a boat ride to bypass the first hill (400 Baht for round trip – which is pricey considering the ride is barely 10 minutes one way).
