Set Dimora Grotta Azzurra on your navigator (Via Campedola 2, Mel Borgo Valbelluna, BL). Drive through the village of Villa di Villa and then through the village of Tiago. At the end of the latter you will find a fork in the road, at which you must bear left towards Zumelle Castle (NOT towards the Boz). Shortly after the junction the road curves sharply to the right and begins to descend (there is a yellow-ochre house in front); there you must NOT descend but turn immediately right onto the level dirt road, at the beginning of which you will also see the sign for the B&B Grotta Azzurra. Follow the road for about 850 metres, after which you will find a dirt road going downhill to the left; take it and you have arrived!
