In September 2023 Collen returned to Switzerland, starting in Geneva and crossing a first stage through France with classics like Col du Galibier, Col du Télégraphe, and Alpe d’Huez before three alpine days in Switzerland. Overnight stops moved from Geneva to Chamonix, then to Belalp where we stayed in a car-free hamlet reached by gondola, onward to Pontresina near the Morteratsch Glacier, and a finale around Grindelwald.
