Néron cave

Néron cave is a prehistoric limestone chamber tucked within a ridge called Serre de Guercy near Soyons, not far from Valence in the Ardèche region. The site contains multiple passages and chambers where both humans and large animals sheltered long ago.

Excavations beginning in 1870 revealed sediment layers holding traces from more than 150,000 years ago. Archaeological findings later confirmed that Neanderthals, modern humans, and Ice Age predators occupied this shelter at different times.

The cave displays reconstructions showing how Neanderthals made fire and crafted tools from stone and bone. These displays help visitors picture daily life as it unfolded within these limestone walls thousands of years ago.

Access is by foot trail with steps climbing from the parking area, taking roughly thirty minutes to reach the entrance. Wear sturdy shoes and bring water, as the path involves significant elevation gain over rocky terrain.

Bears and cave lions also sheltered here, leaving behind bone evidence that archaeologists uncovered during digs. This reveals the site was equally vital to Ice Age predators seeking refuge from the elements.
