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

The photo you saw is real, and the climb is real too. Beneath a natural opening in the cave ceiling is a pavilion dating back to the reign of King Rama V, and when the sun is at the right angle, it shines directly onto the roof tiles. If you want to experience this, you should be there before 11 a.m. If you leave Hua Hin around 8 or 8:30 a.m., you'll enjoy the light and avoid the worst of the heat.

There are two routes. From the parking lot, you can hike over the first hill (approximately 25–35 minutes, with stunning coastal views) or take a boat and skip this section. The second ascent must be tackled on foot; it's steep, and the high humidity makes it strenuous. Sturdy footwear and water are therefore essential—don't underestimate the challenge! At the bottom of the first hill, there's a beach with cafes offering food, drinks, and ice cream—an ideal spot for a break before the more strenuous part. Monkeys along the path are a common sight. When you reach the pavilion, be sure to walk around it. Most visitors just photograph the front and then leave—but the view from the back is well worth the extra minute.
