Getting there & away
Trains to Lucerne (Sfr29) depart hourly from Interlaken Ost train station. Trains to Brig (via Spiez and Lötschberg) and to Montreux (via Bern or Zweisimmen) depart from Interlaken West or Ost.
Main roads head east to Lucerne and west to Bern, but the only way south for vehicles without a big detour round the mountains is to take the car-carrying train from Kandersteg, south of Spiez.
Should you wish to hire a car in Interlaken for trips further into Switzerland, big-name rental companies Avis (033 822 19 39; Waldeggstrasse 34a), near a 24-hour petrol station, and Hertz (033 822 61 72; Harderstrasse 25), are both reasonably central.
