All year. Autumn and winter put the alpenglow lower and often stronger on the Dents du Midi.
70–200 mm is the working lens — it controls how large the mountains sit behind the castle and keeps empty water out of the frame
Walk both sides of the castle before you set up. The relationship between castle and mountains changes fast with a few metres of position.
An hour before sunset, and plan to stay 30 minutes past it for the blue-hour frame.
Train to Veytaux-Chillon (about 6 minutes on foot), bus 201, car, or the lake boat.
