Phraya Nakhon Cave: Thailand's Hidden Royal Pavilion Inside a Cave

Imagine a golden Thai royal pavilion bathed in ethereal light, standing majestically inside a massive cave. This isn't a scene from a movie - it's Phraya Nakhon Cave (ถ้ำพระยานคร), one of Thailand's most breathtaking and lesser-known destinations.

Why Visit?

This is one of Thailand's most photographed natural wonders - a royal pavilion built for a king, hidden inside a cave where sunlight pours through the collapsed ceiling. It's truly magical.

The History: A Pavilion Fit for a King

The Kuha Karuhas Pavilion (พระที่นั่งคูหาคฤหาสน์) was built in 1890 during the reign of King Chulalongkorn (Rama V). The cave had been visited by Thai royalty since 1859 when King Mongkut (Rama IV) explored it. The pavilion was constructed as a memorial to the royal visits and has since become one of Thailand's most iconic landmarks.

The cave gets its name from a local nobleman, Phraya Nakhon, who discovered the cave while seeking shelter from a storm centuries ago.

The Journey: Not for the Fainthearted

Getting to Phraya Nakhon Cave is an adventure in itself. The cave is located in Khao Sam Roi Yot National Park("Mountain of Three Hundred Peaks"), about 3.5 hours south of Bangkok.

The Hike

From the park entrance at Laem Sala Beach, you'll need to:

Climb up - A steep 430-metre ascent through jungle terrain (about 20-30 minutes)
Descend down - Into the first cave chamber and then to the main cave with the pavilion
Return the same way - Yes, you have to climb back up and down again!

Important Warning

The path is steep and can be slippery, especially after rain. Wear proper hiking shoes with good grip. Bring plenty of water - you'll need at least 1-2 litres. Start early to avoid the midday heat.

The Boat Option

From Bang Pu village, you can hire a boat (around 400 THB) to Laem Sala Beach, which saves you a 30-minute walk along the coast. However, you'll still need to do the main climb to reach the cave.

Best Time to Visit

Timing is everything at Phraya Nakhon Cave:

Time of day: 10:30 AM - 11:30 AM is magical - sunlight streams through the cave's collapsed ceiling directly onto the pavilion
Season: November to April (dry season) offers the best weather and clearest skies
Day of week: Weekdays are less crowded than weekends

Pro Tip

Leave your hotel by 7 AM to reach the cave by 10:30 AM for the perfect light. The early start also means cooler hiking conditions.
