Khao Som Phot Wildlife Sanctuary

Despite the English name, Khao Som Phot is officially a non-hunting area (เขตห้ามล่าสัตว์ป่า) rather than Thailand’s stricter wildlife sanctuary category — a distinction worth knowing before you plan a visit. Non-hunting areas protect specific species from hunting while still permitting general access; true wildlife sanctuaries restrict entry to permit holders only. This one covers roughly 8,440 rai (about 13.5 sq km) of forest and limestone hill in Lop Buri province’s Chai Badan district, established in 1995, and there’s no entrance fee.

What’s actually here: a cluster of limestone caves, some open to visitors and some not, an area of exposed granite rock formations known locally as Lan Hin Phut, fossil deposits in the rock, and forest cover that supports the usual central-Thailand species — deer, wild boar, and forest birds among them, though this isn’t a place with staged wildlife encounters or feeding platforms. Sightings depend on timing and patience rather than being part of the itinerary.

Don’t expect a visitor centre, marked trail map, or paved paths. The office keeps set hours — Monday-Friday 07:30-16:30, Saturday-Sunday 08:00-16:30 — and that’s the extent of the visitor infrastructure. It’s a working conservation area first, with tourism as a secondary use of specific, limited features.

Watch out: Confirm access by phone (0 3642 2777) before you drive out, particularly for the caves — not all of them are open to the public, and which ones are can change.

Insider Tip: If wildlife viewing is genuinely the goal rather than the habitat itself, Lop Buri Zoo guarantees sightings in a way this sanctuary can’t — treat Khao Som Phot as a cave-and-rock-formation stop, not a safari.

The sanctuary office sits roughly an hour and a half by road from Lop Buri town, with no public transport to the site. For another nature stop in the same province, Khao Wong Phrachan is a limestone hill with a hilltop shrine and views, reachable on the same day trip.
