If you’re looking to explore one of the most striking natural landmarks in Prachuap Khiri Khan, now is the perfect time to visit the Phraya Nakhon Cave in Sam Roi Yot National Park.
Located an hour’s drive from Hua Hin, the cave is renowned for its dramatic interiors and the iconic royal pavilion, which is beautifully illuminated by sunlight between November and February, according to park officials.
Visitors who time their trip to coincide with the sunlight streaming into the cave between 10:30 a.m. and 11:30 a.m. are rewarded with a view of the “Phra Thinang Khuha Kharuehat” pavilion bathed in golden light. Built during the reign of King Rama V in 1890, the pavilion remains one of the cave’s most photographed features.
The cave has long been a destination of historical and royal significance. King Rama V, also known as King Chulalongkorn the Great, built the pavilion during a visit to the area. Later, King Prajadhipok (Rama VII) and King Mongkut also visited the cave, leaving their names inscribed on its walls. H.M. King Bhumibol Adulyadej The Great (Rama IX) is also believed to have visited the site.
Reaching the cave
Getting to Phraya Nakhon Cave offers an adventure in itself. Visitors can choose to hike from Laem Sala Beach, with the trek taking 30 minutes to an hour depending on pace and fitness level. The trail includes steep sections with hand ropes for support, so proper footwear is essential. Alternatively, a boat service from Bang Pu Beach to Laem Sala Beach is available for approximately 400 baht per trip, accommodating up to six passengers. However, the boat service may be unavailable during high tide or adverse weather.
Exploring the cave
Once inside the cave, visitors are greeted by two main chambers, each with unique features. Aside from the pavilion, the cave also offers unusual stone formations and a sense of natural grandeur. The opening in the cave’s roof allows sunlight to flood the interior, creating a dramatic effect.
The national park imposes an entry fee for visitors, with rates set at 200 baht for foreign adults, 100 baht for foreign children, 40 baht for Thai adults, and 20 baht for Thai children. Tickets can be purchased at the park office, which also offers parking, restaurants, and souvenir shops.
Popularity on the rise
Recent statistics highlight the increasing appeal of Sam Roi Yot National Park. In October 2024 alone, the park welcomed 11,673 visitors, generating over 1 million baht in revenue from entry fees, accommodation, and other services. The Phraya Nakhon Cave remains a standout attraction for both domestic and international tourists.
Open daily from 8 a.m. to 3 p.m., the cave is a must-visit for those looking to experience its natural beauty and historical significance. Whether choosing to hike or take a boat, the journey is a rewarding one for those keen on exploring one of Thailand’s most impressive natural landmarks.
