Phu Nam Chan Forest Park

Phu Nam Chan is a fossil-bearing hillside in Kuchinarai district, Kalasin province, about 70 km east of Kalasin town. Its main claim to fame isn’t a viewpoint or a waterfall — it’s the ancient fish fossils exposed in the rock here, estimated at roughly 250–300 million years old, which make the site one of the recognised points on the Kalasin Geopark, a locally designated geological heritage network established in 2022. Officially, Phu Nam Chan is a wana uthayan (forest park) rather than a full national park — a lighter designation under Thailand’s parks department, with no permanent ranger station or ticket gate.

The approach itself is half the reason people come. The road in winds through rubber plantations that give way to rice fields, well-maintained enough that it’s become a minor weekend destination for motorcyclists doing scenic loops through this part of Kalasin, fossils or no fossils. At the site, the fossil-bearing rock is exposed in situ rather than displayed behind glass — this is a field location, not a museum, so what you see is the actual outcrop where paleontologists have identified and recorded specimens.

Insider Tip: Combine the visit with Phu Faek Forest Park (Dinosaur Footprints) or the exhibits at Sirindhorn Museum in Sahatsakhan — together they cover Kalasin’s paleontological sites properly instead of taking in one fossil location in isolation.

Watch out: There’s minimal English signage explaining what you’re looking at, and no gift shop or visitor center on site — bring a guide, a pre-trip read, or low expectations for on-site interpretation. This suits travelers genuinely curious about the geology, not a family day out looking for a polished attraction.

No entrance fee is charged since there’s no staffed gate; bring your own water, as facilities are minimal. A car or motorbike is the only realistic way in — public transport doesn’t reach the site.
