Amsterdam is truly a biker’s city, although pedaling along the labyrinthine streets can get a little chaotic. Stick to walking and you won’t be disappointed.

The Anne Frank House is one of the most moving experiences a traveller can have, and the Van Gogh Museum boasts a sensational collection of works.

Nice has a cosmpolitan Riviera vibe, and you'll enjoy exploring its fashionable boutiques and restaurants and sunning yourself on its popular beaches.
