Inside the park, we face a climb of less than a kilometre and a half but very intense, with curves that offer spectacular views of the Mediterranean. At the top, we begin a rapid descent on gravel that takes us to the Pantà de Foix, a peaceful setting surrounded by Mediterranean forest and vineyards. The reservoir, built in the 19th century, is now a key biodiversity site, presided over by Castellet castle, which dominates the valley from a hill. We circle the reservoir on a small road before tackling the last 15 km of the stage.
