Once past the village of Bugarach (approximately 2 km) in the direction of Rennes le Bains, look on the right side for a large sign "Roman bridge"(Pont Romain). Parking is available down the path to the river and the Roman bridge. Hung between two limestone walls, it overlooks natural basins with a waterfall. It overlooks the creek of La Blanque, a tributary of the Sals.
