Do Ao Noi, or Wat Tham Phra Non, was built as a temple in 1987 and received its royal deed for boundary markers in 2010. Although the temple is relatively new, it houses two large, reclining Buddha statues, estimated to be between 300 and 500 years old. The first statue, 20 meters long, is located at the cave entrance, on the right-hand side. The second statue, 14 meters long, lies inside the cave, on the left-hand side. It is believed that Tham Phra Non was often a refuge for sailors during storms in the past.

Wat Ao Noi, like Tham Phra Non, deserves special mention. Located inside a cave, it requires climbing a staircase to reach. From the top, visitors are rewarded with breathtaking sea views and can rest if the climb proves too strenuous. Wat Tham Phra Non lies at the foot of the Ao Noi Mountains in Prachuap Khiri Khan Province. The beauty of Wat Ao Noi

The golden teakwood church is adorned with exquisite Thai patterns. It is of great value and difficult to find. Inside, a marble Buddha statue and intricately framed paintings depicting scenes from the life of Buddha decorate the church walls. Two golden, nine-headed nagas surround the chapel. Ao Noi Beach stretches out in front of the temple, its cool sea breeze creating a beautiful atmosphere while providing shade from the mountains. A nature trail leads from the temple to the cave of the Reclining Buddha on the mountain. After a 10- to 15-minute climb, visitors have the opportunity to enjoy the sea view from above, pay homage to the beautiful Reclining Buddha (in the style of contemporary Uthong Rattanakosin art), and ask for his blessing.
