Swiss Alps. Interlaken sits between two lakes and is the classic base for high-mountain railways, cable cars and hiking. Summit excursions are costly, so check live mountain webcams before paying — cloud can hide everything. Lucerne adds lake cruises and gentler peaks, while Lake Geneva pairs mountain views with terraced vineyards on its northern shore.
Austrian Alps. Innsbruck is unusual: a cable car climbs from the city centre to high alpine terrain in well under an hour, so you can combine a morning in the old town with an afternoon above the tree line. Hallstatt's lake and mountains make it one of Europe's most photographed villages.
Norwegian Fjords. Bergen is the gateway to UNESCO-listed fjord scenery. Fjord cruises, scenic rail and ferries link sheer cliffs, waterfalls and tiny farms. Further north, Tromsø is a popular base for northern-lights trips, and the Lofoten Islands offer hiking, kayaking and Arctic beaches.
Plitvice Lakes. Croatia's best-known national park is a chain of sixteen terraced lakes linked by waterfalls, explored on wooden boardwalks. Swimming is not permitted. Arrive at opening time to walk the boardwalks before tour groups.
Keukenhof. In spring, this garden near Amsterdam bursts with tulips, daffodils and hyacinths. It opens for only a few weeks each year, roughly mid-March to mid-May.
