Description

Before you lies the impressive entrance of Trou Maulin (or Nou Maulin), gateway to a Geopark-listed underground network spanning over 1.6 km. On the left wall, spoon-shaped hollows known as "scallops" record the flow of ancient turbulent currents plunging underground. Around 1900, a levee was built to keep the river on the surface for local mills and hygiene. However, during floods, the Lhomme overwhelms the barrier and vanishes into the cave, resurfacing 3.8 km away at Éprave!

Warning: Approaching the entrance during high water is extremely dangerous. Exploration of the inner galleries is restricted to trained speleologists.
