Why it matters
Why Salkhan Fossils Park (Sonbhadra Fossils Park) is worth your time
Salkhan is a window into some of the oldest life on Earth. Stromatolites are among the earliest traces of living things, and a park where they sit in the open on a hillside is rare. The site was found by geologist John Bicknell Auden of the Geological Survey of India in 1929, drawn to wider attention in 2001, and inaugurated as a fossil park on 8 August 2002.
It has also been nominated to UNESCO's tentative list of World Heritage Sites (2025), and the Birbal Sahni Institute of Palaeosciences has been researching it since 2024. For a visitor, it turns an ordinary hill into a question about deep time.

Plan your visit
How to experience it
Drive out from Robertsganj on the state highway towards Salkhan; the park is about 12 km away. It lies beside the Kaimoor Wildlife Sanctuary, so you may pass forest and hill scenery on the way. Start with any signage or a local guide to learn what you are looking at; the fossils appear as layered, domed or wavy patterns in the rock.
The fossils are stromatolites, layered structures built by cyanobacteria, and algae, from the Mesoproterozoic era, about 1.4 billion years old. They occur in five patches across the park's 25 hectares. Follow the trails, look carefully, and photograph without touching.
Plan the visit in the morning and leave time for a rest at the nearby town. Carry water and sun protection, as shade is limited. Do not expect a museum; the interest is in the rock itself.
