We had left the train at Bernina Suot at 0940 & got to Poschiavo at 1530 even though it was downhill most of the way & quite tired. Poschiavo was a surprise. We had a beer & gelati in the tiny main square. Although it is still Switzerland, the town is pure Italy. In fact, the valley crests are the frontier with only the valley Swiss. Here, you can see from one side of Switzerland to the other. I said, ‘Bezahlen, per favore’ without thinking. Then, the spectacular train journey back with the track leaping back & forward to get the height (Poschiavo is only 1080 metres, Cavaglia is 1693 metres, which happens to be 5555 feet & the Bernina Hospice (the top) is 2256m). We were very tired by the time we got back to the ‘Post’ where we got two dinners again - Berner Teller mit sauerkraut which Dad had not had before. I missed a trick when I booked up. I should have said that Dad was 68 & we might not have been put on the top floor!
