Pantano del Foix. Road between Castellet and Vilanova i Geltrú. Lots of traffic but the road surface is in very good condition. Asphalt. Watch out for Sunday drivers.

Swamp that has the same name as the river that supplies it with water and that comes from the mountains of the Anoia area and nearby mountains. The green area is beautiful!
