We are visiting Lake Iseo in late September for a week (staying in Sarnico). We shall be reliant on public transport. There appears to be a limited boat service from Sarnico from early September so we are wondering if there is a bus service to visit other places on the lake. I know the bus from Bergamo stops at Sarnico and carries on to Tavernola but is there a service the other direction to Iseo Town? From there we could catch the train to visit the east side of the lake and there also appears to be a more frequent boat service from Iseo in the winter months. Any advice to help us explore the lake appreciated.
