Rap Ro Cave or Wat Thep Charoen is located on Rap Ro Hill, also known locally as Khao Phra, within the grounds of Wat Thep Charoen in Tha Sae District, Chumphon Province. This limestone mountain stretches along a north–south axis and once served as an important cultural and strategic center. Historically, the area formed part of the ancient city Utumporn, an old port town and frontier checkpoint along the Malay Peninsula land bridge. Due to its significance, the Rap Ro Hill area was officially declared a National Archaeological Site in 1936.

Rap Ro Hill contains several notable caves, each holding archaeological artifacts, ancient art, and religious heritage. One of the most important is the Buddha Image Cave, home to Luang Pu Lak Mueang, a highly revered Buddha image believed to protect the town. The cave also contains more than 577 small crowned Buddha images in the Māravijaya pose, arranged throughout the chamber—an extraordinary collection of historic Buddhist art.

Another key highlight is Ai Tay Cave (or Ai Te Cave), where visitors will find an unfinished ancient reclining Buddha painting on the wall. This artwork is believed to date back to the Ayutthaya period, demonstrating early Buddhist artistic influence in the region. Today, part of the cave has been adapted as a Vipassana meditation area, offering a peaceful environment for spiritual practice.

Other fascinating features within the Rap Ro Cave complex include Sai Cave, once a resting place for high-ranking nobles and adorned with elegant stalactites and stalagmites. Visitors can also see the Sandstone Buddha Footprint, intricately carved with the 108 auspicious symbols, reflecting exceptional craftsmanship.

At Sala Ratsamakkee, the preserved body of Luang Pu Sai, a former monk of Wat Thep Charoen whose body remains remarkably undecayed, is enshrined for devotees to pay respects. This phenomenon has become one of the spiritual highlights of the site.

With its combination of archaeology, religious heritage, ancient art, and local legends, Tham Rap Ro stands as a uniquely rich destination that reflects Chumphon’s cultural depth and historical identity.
