Phraya Nakhon Cave, Khao Sam Roi Yot National Park, Prachuap Khiri Khan Province.

After visiting many places, I personally rank this as the number one unseen spot 👍. The journey began after seeing promotional photos. We drove to a temple near the sea. From there, you can either take a boat to the beach where the path to the cave starts or hike over the hill yourself. Naturally, we chose to hike (if you're not up for it, take the boat). The hike was quite exhausting, with steep paths that took away half of our energy. After descending the hill, we reached the beach where boats dock. There are places to rest, wash your hands and face, and prepare for the next leg of the journey. The next part of the path is even tougher, with sharp rocks that require careful navigation. There are warning signs for those with chronic illnesses to avoid this path. But once you reach the cave, it's absolutely worth it. The cool, bat-free air inside the cave is refreshing. The locals mentioned that the structure inside was assembled here, and it's truly magnificent. You have to see it with your own eyes.
