I drove from Biel/Bienne to there last spring and went over the Neufennen Pass because the Gotthard Tunnel was closed due to last years rock fall, it was spectacular and I made a point of coming back the same way and the view was totally different.
Going to Lugano the above route is steep up and gentler down and obviously the opposite coming back. Dont ride a bike

, I saw some nutters doing that last year!!!
