From the south, the most natural (and most famous) climb starts in Tèsero (988m), which is a very hard climb. The other south variants are about as hard or tougher still. I suggest some variants in my map below, none of them conforming exactly to the way I went up here. I went from Molina (811m) to Cavalèse (1003m) and then I think I took the serpentine road to Daiano and then up over the Passo di Pramadícco (1443m (1451m)) to Stava (1280m) and up to the pass. If coming from Passo di San Lugano (1100m), you would do well to take the road via Carano and over the Passo di Pramadícco and up from Stava. There is a seemingly harder variant more straight up from Cavalèse than the one I think I took that is probably more fun if going via Cavalèse, but the road via Daiano is probably the only appropriately sign-posted. The road from Stava is quite steep and often above 10%. At the Alpe di Pampeago (1757m) a gravel road (R1) takes you in a few easy kilometres to the top (there is even a short bit that is asphalted). Upon reaching the top of the road (2004m) the asphalt returns.

The northern climb could be started already down in Bolzano (266m), and thus it becomes a very hard and long climb. You would climb the famous Eggental/Val d’Ega road. This has two long new tunnels at the start, but one should be able to use the previously unusable old road that is very nice in this part (it was being cleaned up in 2010, but not sure if it was finished, but the idea is that it should be maintained for bicyclists and others). This is one of a couple of roads I still have to visit in the area myself. The road is very narrow on the last section on the north side from Obereggen/S. Floriano (1512m). A nice alternative is to take the road over Obergummer, but it is a little more obvious choice if heading for Karerpass/Jouf de Ciareja/Passo di Costalunga (1752m), so I include it there instead.

If coming down from the Karerpass or Nigerpass/Passo Nigra (1688m) one starts at Birchabruck/Ponte Nova (876m). If coming down from Passo di Lavazè/Lavazè Joch (1807m) one starts at Rauth/Novale (1280m). Finally, if coming from Ora/Auer (247m) over Aldein/Aldino and Deutschnofen/Nova Ponente, you will start a bit down below Rauth/Novale at turn-off (1130m) for Weissenstein/Pietralba (1520m) and these villages.
