Read at source. The instrument is made under section 7 of the Act of B.E. 2504 and registers monuments across Trang, Phang Nga, Phuket and Ranong; item 1 in the same announcement is Kantang railway station. At about fifty-two rai this is by a wide margin the largest declared monument area in the province, because what is registered is the hill and its cave system rather than a building. The declared figure matches the register's own boundary record to the square wa.

Founding

When was it founded — and what actually establishes that?

Thai temple histories mix two different kinds of statement, and this guide keeps them apart. What a register, a gazette entry, an inscription or a dated royal act shows is one thing. What the chronicles and the temple itself hold is another, and it is worth telling as what it is.

What the record showsThe Fine Arts Department register and the SAC archaeological database both record prehistoric material from the caves — tripod pots and polished stone axes from Tham Hoi Khong in particular — and the SAC database gives the site three occupation ranges: around three to four thousand years ago, the twentieth to twenty-fourth Buddhist centuries, and the twenty-fifth to twenty-sixth. The register and the database also record the royal visits: Prince Naris on 31 May 1902, King Vajiravudh twice, and King Prajadhipok in B.E. 2471, who cut his cypher ป.ป.ร. into the uppermost cliff face.
What tradition holdsTradition rather than record explains most of the cave names. Tham Ruesi, the hermit's cave, is said to have been called the cave of bones until B.E. 2495, when Phra Baidika Nimit Sumangkhalo had the bones gathered and burnt and a figure of a hermit built at the mouth. Tham Champa is said to be called Tham Sawoei, the dining cave, because King Vajiravudh took a meal there.

Two things do not reconcile. The register narrates a visit by King Prajadhipok on 10 February B.E. 2471, while the cypher he left is recorded by both the register and the SAC database as reading ปปร and ๑๐/๑๐/๗๑ — a date of 10 October, not 10 February. And the number of caves is given as six levels by the Fine Arts Department register and the SAC database, but as eight caves by the Tourism Authority of Thailand, which names a different set.

History

The history of Khao Pina

Khao Pina is one hill standing on its own out of the rice land at Na Wong, limestone, about a hundred meters high, with a tarred road running round the foot of it. The caves inside are stacked rather than spread, and the register sorts them into six levels reached by stairs that get steeper as you go up. At the bottom, below ground level, is Tham Nam, permanently flooded, with a watercourse running under the hill. At the top are a terrace of rock you can sit on and look out from, and a cliff face with a king's initials cut into it. Between those two things is about four thousand years.

The archaeology is at the bottom and in the side chambers. Tham Hoi Khong produced polished stone axes and tripod pots — หม้อสามขา, the three-legged vessel that marks the prehistoric coastal cultures of the Thai-Malay peninsula. A survey by the Phuket regional office in B.E. 2556 found a separate shelter and cave on the north side, locally called Tham Khi Wua, with earthenware sherds and stone tools in a chamber partly filled by roof collapse. The SAC database places the earliest occupation three to four thousand years ago, and then two much later phases, which is the normal shape for a limestone hill: people shelter in it, leave, and come back when it becomes a sacred place.

The second level holds Tham Ruesi, and its story is a small lesson in how caves get renamed. It was called the cave of bones, because that is what was in it — a great quantity of old human bone. In B.E. 2495 a monk, Phra Baidika Nimit Sumangkhalo, had the bones collected and cremated and a figure of a hermit set up at the mouth, and the hermit's name stuck. Above that, on the third level, is Tham Phra Banthom with a reclining Buddha built in a hard lime plaster, made when Khun Krai was abbot about a century ago by a craftsman named Nai Nui Suwannakhiri from Ban Khuan Khan in Mueang Trang. The fourth level holds five more images in the same material, of which the register says one is of unknown age and four are later. The fifth holds a chedi nobody can date, restored under Khun Krai, with his ashes walled into a lotus-shaped plinth by his descendants in B.E. 2466.

What put Khao Pina on the map was royalty. Prince Naris came on 31 May 1902. King Vajiravudh came twice, on 19 May B.E. 2452 and 30 June B.E. 2458 according to the register, with a further visit in B.E. 2453 in the SAC account of Tham Champa — three dates for two visits, which nobody has reconciled. King Prajadhipok came in B.E. 2471 and left his cypher, ป.ป.ร., cut into the topmost cliff. The register dates that visit to 10 February; the inscription itself carries ๑๐/๑๐/๗๑, which is October. One of the two is wrong and the page does not know which.

On site

What you actually see

The six levels of the cave system as the Fine Arts Department register sets them out, from Tham Nam below ground level, permanently flooded with water running under the hill, to the open terraces at the top.

The royal cypher ป.ป.ร. cut into the uppermost cliff face, with the figures ๑๐/๑๐/๗๑ beside it.

Tham Phra Banthom on the third level, with a reclining Buddha built in hard lime plaster about a century ago by a craftsman from Ban Khuan Khan, made when Khun Krai was abbot.

Tham Phra Ong Klang on the fourth level, with five lime plaster images, one of which the register says cannot be dated and four of which are later work.

The chedi on the fifth level, of unrecorded date and badly decayed before Khun Krai restored it, with Khun Krai's ashes set into a lotus-shaped plinth by his descendants in B.E. 2466 and a modeled likeness of Khun Naiyanapaya, the headman who looked after the hill while the monastery stood empty, behind it.

The view terraces at Tham Champa and Tham Makham on the top level, with Buddha images set on the rock shelf that runs out from them.

Visiting

Visiting: hours, admission, dress and photography

This is a working place of worship for millions of people rather than an attraction, and it is treated as one at the gate. Where a figure below is blank, no source we are prepared to cite states it.

HoursDaily, 9.00 to 17.00, per the SAC archaeological database
AdmissionNot established from an official source.
DressA sacred site with monastic use as well as an archaeological one. Cover shoulders and knees; remove shoes before entering the shrine chambers.
PhotographyNo source we found states a rule, so we print none.
Getting thereNa Wong subdistrict, Huai Yot district, about 35 km north of Trang town. A tarred road about 1.2 km long runs round the foot of the hill. The stairs between levels are steep and there are six of them.
Before you rely on the figures aboveThe hours come from the SAC archaeological database, which also names the three bodies that manage the site: Wat Khao Pina, the National Office of Buddhism and the Royal Forest Department. The Tourism Authority of Thailand's page for the cave renders only a live open-or-closed state and publishes no schedule at all, so it could not be used. No official source publishes an admission figure.

FAQ

Khao Pina: common questions

Is Khao Pina a temple?

Not exactly. What is registered is the hill and its caves, about fifty-two rai of it, and a monastery uses part of the site. The SAC database names the monastery, the National Office of Buddhism and the Royal Forest Department as joint managers.

What are the opening hours?

Daily, 9.00 to 17.00, according to the SAC archaeological database. The Tourism Authority of Thailand's page publishes no schedule, only a live open-or-closed state, so nothing could be taken from it.

How old is the site?

The SAC database gives three occupation ranges: around three to four thousand years ago, the twentieth to twenty-fourth Buddhist centuries, and the twenty-fifth to twenty-sixth. Tripod pots and polished stone axes came from Tham Hoi Khong.

Whose initials are on the cliff?

King Prajadhipok's. He cut the cypher ป.ป.ร. into the uppermost cliff face during a visit in B.E. 2471, recorded by the Fine Arts Department register.

Is it a hard climb?

The register describes stairs between six levels and says they are very steep. There is a tarred road round the foot of the hill about 1.2 km long.

Where to go from here

Before you go, read the guide to Buddhism and temple etiquette in Thailand — dress, footwear, where photography is not welcome and how to behave around monks. The rest of Trang’s temples are covered here too.

Every temple here sits in a place worth reading about on its own terms. The nationwide temple guide covers the other provinces to the same documentary standard as this page, and says on each one what the record establishes and what it does not.

If you are thinking about more than a visit: work out which Thai visa route fits your situation, and see what is available to rent and buy in residences across Thailand.
