As well as the two big sports, rugby and Basque pelota, you can do practically all sports here thanks to the geographical diversity of the area:
hiking (main hiking routes and coastal tracks, more than 5,000 km of signposted paths);
extreme sports (potholing, rock climbing, paragliding …);
whitewater sports (rafting, canyoning, sea kayaking…);
surfing (from Anglet to Guéthary, the spots attract surfers from all over the world); golf (11 courses);
cycling (cycle tourism, mountain biking, the Tour de France which comes each year to Pau and the big Pyrenean cols…).
There is even skiing (3 downhill ski resorts and 3 cross-country resorts).
