As David says, great if you like hairpins. I love em! Magic.
This route is Passo di Campolongo and, for me, worth a trip over and back - once. With the other surrounding passes being so great, Pso Camp just doesn't rate unless one wants to beeline it as a shortcut to/from Arabbas - Corvara. Like all of the Dolomites, the scenery is wonderful.
Can be combined as a circuit with the SS243 and the Pordol pass. Great if you love hairpins!
