When will the 2026 dates be available for the 12 day Best of Switzerland tour?
Tour dates are usually announced in March or April for the following year.
However, to estimate when the tours may start, just look at 2025. Is the tour you are interested in starting on the 2nd Monday of the month? Then go to a 2026 calendar and see what the date is of the 2nd Monday of the month. Not a sure way to know, but usually pretty accurate.
