From Levico Terme first again to Caldonazzo on SP 1. at the Caldonazzo lake turn left - continue on SP 1. after the climb turn left again - SS 349 - to Carbonare (wonderful curve combinations!!!). Turn left and then right onto the SS 350 and after a wonderful descent into the valley, follow it to Pedescala for the turn-off to Asiago. This is followed by an ingenious route uphill - simply a pleasure!
In Asiago continue straight ahead on the SP 76 to Foza (approx. 13 km). Here turn right onto the SP 73 to Valstagna - downhill again a great motorcycle track with wonderful curves! In the valley, first turn left and then immediately right over the bridge and continue on the other side (turn right) in a south-easterly direction. Continue on the SP 47 until Torre. Turn left here (SP 74) and continue to Romano D'ezzelino. Turn left up to Monte Grappa. At the top, turn right and then down into the valley again with lots of bends - until shortly after Romano D'ezzelino. Then it goes left via Crespano del Grappa, Possagno, Caniezza to Pederobba. Then first right and immediately left again to San Vito di Valdobbiadene. Then on to Valdobbiadene. Keep left here onto the SP 143, which leads to Pianezze and Combai and then on via Miane and Follina to Cason di Valmarino. Shortly afterwards turn left over the Passo di San Boldo to Trichiana. The Passo di San Boldo leads up through several single-lane tunnels with hairpin bends - traffic lights regulated. A special feature, which - as far as I know - does not exist anywhere else in the Alps! Then further over San Felice to Bribano. There turn left onto the SS 50 - later SP 35 - to Feltre. There turn right to Pedavena and continue over the Passo Croce D'Aune. Continue via Faller to Pte. d. Serra. There turn right onto the SS 50 and at the roundabout left onto the SP 40 up to Castello Tesimo. Via Pieve Tesimo the route continues to Strigno and Telve. In Telve turn right. At the turn-off to Passo Manghen continue straight on (SP 65)!  Via Torcegno and Ronchi to Roncegno and from there on SP 228 back to Levico Terme. Total distance 330 km
