Khao Nang Phanthurat Forest Park

Khao Nang Phanthurat Forest Park has been protecting its folk-tale limestone hill for barely five years. The Royal Forest Department only gazetted the 2,009-rai (322-hectare) site as a forest park on 22 October 2020, published in the Royal Gazette on 5 January 2021. The legend it’s named for is far older: a limestone hill riddled with caves and short trails behind Cha-am, about a two-hour drive from Bangkok, carrying a Thai folk story in its rock formations.

The Sang Thong legend

Local tradition ties the hill to the Sang Thong folktale: a giantess named Phanthurat is said to have raised the hero Phra Sang in secret, only for him to escape using a magic disguise he found here. Grief-stricken, she died searching for him, and her body is said to have become the mountain, which is why sections of the park carry names straight out of the story, including “Phanthurat’s Cinerary Urn” and “Phanthurat’s Looking Glass,” alongside a shrine to Phanthurat herself. Past the trailhead, the limestone gives way to genuinely leafy forest, a sharp contrast with the flat rice country around Cha-am.

Caves, viewpoints and what else is there

The marked nature trail passes named caves (Tham Mayom and Tham Chaeng among them) and several viewpoints, including one overlooking a spot called the elephant corral (Khok Chang). There are natural pools, a tent-camping area for anyone who wants to stay the night, and the park lists cycling and mountain biking among its activities alongside birdwatching and butterfly-spotting. An information pavilion near the entrance covers the site’s background, plus a shaded rest area where local families picnic on weekends.

Insider Tip: Go in the cooler morning hours. The trails have little shade in the open limestone sections, and the caves are the most comfortable part of the walk once the sun is up.

It’s a modest, low-key stop rather than a marquee attraction. Birdsong and the occasional other hiker are about as busy as it gets on a weekday. Most visitors pair it with a beach morning or afternoon at Puek Tian Beach or a stop at Maruekhathaiyawan Palace, both a short drive away.

Watch out: Cave and trail access can vary with weather and upkeep at small forest parks like this one; confirm current conditions with park staff (086 761 3113) rather than assuming every named feature is open.

Planning your visit

Off Phetkasem Highway between Phetchaburi and Cha-am, turn at the San Layang junction and follow the Ban Kaet road roughly 4.5km to the entrance. There’s no published entry fee, and the park’s own listed hours run daily from around 09:00 to 16:00, though it’s worth confirming by phone if you’re planning to arrive late in the day.
