Hi John:
I was on the Best of Italy tour in 2022 and fell in love with the Dolomites immediately! So much that the following year, I took the RS Alpine My Way Tour because it included the Dolomites. But, before joining the tour group in Salzburg, I pre-tripped from Venice to Kastleruth for a few extra days in the Dolomites. I joined one of the local guides, Viktor, on his hike with a small group of other tourists from the Hotel Villa Kastleruth. (That’s the “sister” hotel of where the RS Alpine Tour stayed.) I would have never attempted such an intense hike on my own.
The hotel was half-board so breakfast and dinner included (boy, do they know how to feed their guests, even this vegan!). They have a pool, sauna and whirlpool, afternoon snacks and attentive staff. The guided hikes are 3 days a week, and they can recommend other nearby sites/tours. It seemed like many of the German visitors stay for the week. One of the couples did the 3 day hikes then used the bus to visit nearby castles and other villages. I even went there for dinner one night when the RS tour returned to the village later that week. It was that good :)
It’s easy and inexpensive to get there on public transit. I took the train from Venice to Bolzano, to connect to the (#172?) bus up into the mountains to Castelrotto. Other villages are connected to the bus. It is like a world away! I hope you find a good match for your visit!
