Ice skating on the frozen ponds and lakes of Jura and Doubs is a long-standing tradition that goes back a hundred years or so. Every winter, a long period of freezing weather has the most daring locals out testing the ice. The bigger the lake, the more solid and longer-lasting the ice.
This explains why Lamoura Lake in Les Rousses is often the first to be viable for skating. The ice has to be at least 10cm thick, otherwise beware! Skaters are each responsible for their own safety. Find out beforehand whether the ice is safe, comply with the instructions and never go beyond the designated areas.
