The Phraya Nakhon Cave consists of two huge chambers and both chambers are open to the sky allowing the rays of the sun illuminate the chambers giving the cave a magical feel that is both tranquil and serene. The Phraya Nakhon Cave is best known for the Kuha Karuhas Pavilion found in the main chamber (shown in the photo above). The Pavilion was built at the end of the 19th century for the visit of King Chulalongkorn the Great (Rama V). The cave was later visited by King Prajadhipok (Rama VII) and the present King of Thailand, King Bhumibol Adulyadej (Rama IX). The cave wall of the main chamber contains the signatures of both King Rama V and King Rama VII, further documenting their royal visits.
Reaching the cave requires quite a bit of effort, beginning at the car park of Bang Pu village, where you can either take the trail across the rocky peninsula (around 30 minutes) or take a short longtail boat trip to Laem Sala beach. The boat round trip will cost around 300 Baht per person. Then it is just over 400 meters walk, mostly up hill on a steep and rocky path to the cave. There are great views of the beach, the sea and a number of small nearby islands of the way to the Cave.
