This epic 23 day trail through Europe balances all the sightseeing icons with unexpected marvels and underrated destinations. From walking the cobbled streets of Michelangelo's Florence and seeing Paris lit up at night, to a sobering WW2 education in Poland and bunking down amid snow-capped mountains in the Swiss Alps, this is a barnstorming European best-of. Because we don't want you to miss out on the unmissable.
