Once Interlaken made the Victorians swoon with mountain vistas from the chandelier-lit confines of grand hotels; today it makes daredevils scream with adrenalin-loaded activities. Straddling the glacier-fed Lakes Thun and Brienz and capped by the pearly white peaks of Eiger, Mönch and Jungfrau, the town is the gateway to Switzerland's fabled Jungfrau region and the country's hottest adventure destination bar none. If the touristy town itself leaves you cold, the mountains on its doorstep will blow your mind, particularly if you’re abseiling waterfalls, thrashing white water or gliding soundlessly above 4000m summits.
