Route: Total Barcelona
Distance: 66 miles
You'll feel ready for the Vuelta a España after climbing 8,400 feet around the Collserola hills — high above the spires of Gaudí's Sagrada Familia. While you've never suffered on the bike quite like this, the views along the route are among the most spectacular in Spain: from the mountaintop town of Santa Creu D'Olorda, with its ancient castle of Castellciuró, to the wild beauty of the Coll de la Conreria. Whether you do the full ride or just sample a few of the epic climbs, it's worth coming up here to experience a different side of the city.
