Khao Pu-Khao Ya National Park

Khao Pu-Khao Ya National Park shuts its gates every year from 15 November to 25 December, while the northeast monsoon dumps its heaviest rain on the Nakhon Si Thammarat range: a scheduled closure, not damage or disrepair, that several of Thailand’s southern parks share and that most travel write-ups of the park never mention. Locals call the range “ป่าพรหมจรรย์” (Brahm Forest), and the reserve spans three provinces (Phatthalung, Nakhon Si Thammarat, and Trang) over roughly 694 square kilometres (older listings round up to 701). It became Thailand’s 42nd national park by a Government Gazette announcement on 27 May 1982. The Phatthalung entrance, at Khao Pu subdistrict in Si Banphot district, is the one most visitors use.

Forest, caves, and wildlife

Despite what some listings claim, this isn’t a coastal mangrove park: it’s mostly moist evergreen forest over limestone, with pockets of drier deciduous woodland lower down the slopes. Its highest point, Khao Hin Taan, rises to 877 metres, the tallest peak in Phatthalung province. Two caves anchor the main trail network: Tham Matcha (“fish cave”), which opens onto an underground pool roughly 100 metres wide, ringed with stalactites and about ten Buddha statues, and Tham Ruea Thep Nimit, which local belief holds shelters the spirit of an ancestor. Wildlife records for the park run to around 162 species, including dusky langurs, wild boar, and a range of forest birds. Sightings are opportunistic, and early morning gives the best odds.

Watch out: Tham Matcha closes to visitors at 16:00 even though the park gate stays open later: the cave paths get slippery once the light fades, and staff won’t let you in after that cutoff. Trail markings elsewhere can also be inconsistent away from the main paths near the entrance, so check with park staff about which routes are currently maintained before heading further in.

Why it stays quiet

Quiet is the park’s other main draw. Visitor numbers stay low compared to Thailand’s headline parks, and the forest canopy keeps most trails shaded even at midday. Morning mist settles over the ridgelines in the cooler months, usually burning off by mid-morning.

Planning your visit

Outside the November-December closure, the driest, most comfortable hiking weather runs January and February; from March the heat builds and shade becomes more valuable than ever on the exposed limestone stretches. The park is best reached with your own transport: there’s no scheduled public transit to the entrance. Bring water, insect repellent, and shoes with real grip for the limestone trail sections.

Insider Tip: Call the park office (0 7430 7114) before you drive out in October or early November: the closure dates shift slightly year to year around the monsoon, and turning up to a locked gate after a long drive from Phatthalung town is an easy mistake to avoid with one phone call.

Nearby

Thale Noi, Phatthalung’s Ramsar-listed waterbird wetland, and Tham Sumano, a limestone cave elsewhere in the province, make reasonable pairings if you’re building out a day of Phatthalung’s natural sites around a visit to Phatthalung town.
