European Trail (Start London, Gap, 23 Days)

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 being blown away by the fairy-tale beauty of Slovenia's Lake Bled, getting a sobering WW2 education in Poland and bunking down amid snow-capped mountains in the Swiss Alps, this is a barnstorming European best-of with a group of 18 to 22-year-olds to keep you laughing throughout. Because we don't want you to miss out on the unmissable.
