Carcassonne to Sète

S1, E4: David and Hugh are on the final leg of their journey to the Mediterranean coast. They head to Somail where much to David's delight they give the biking a break and take a boat ride along the Canal du Midi. Hugh soon has them back in the saddle, and they head to the city of Beziers to see the engineering genius behind the Nine Locks of Fonseranes. After that, a visit to a Languedoc vineyard for some wine and cheese tasting then it's the final push to the coast and the seaside town of Sète.
