I have booked a flight for six people from Stansted to Bergamo and a hotel at Pisogne. Early June. Cannot find advice on travel between Bergamo and Pisogne. Would like to visit Riva on Lago del Garda during my four day stay at Pisogne if possible. Visited Riva when touring by car sixty years ago. This trip is to celebrate my 80th birthday with younger friends and I want to introduce them to this beautiful area of Italy. Would very much appreciate your advice.
