Bern vs Interlaken

Bern

Bern sits at 540 m on the Swiss plateau between the Jura and the Alps, with a temperate continental climate. Summers are warm with frequent thunderstorms; winters cold with occasional snow that rarely accumulates in the Old Town. The Aare river horseshoe creates a noticeable microclimate — warmer in winter, cooler in summer than the surrounding plateau. Bern receives about 1,000 mm of precipitation a year spread across the seasons; the foehn wind from the Alps occasionally brings warm dry conditions and exceptional clarity.

Interlaken

Interlaken town sits at 568 m in a valley with a relatively mild alpine climate, but the mountain destinations it serves range from 1,000 m (Grindelwald) to 3,454 m (Jungfraujoch). Temperature drops roughly 6°C per 1,000 m gain — a pleasant 22°C day in town means 0°C at the Jungfraujoch. Clouds are a serious consideration: the Jungfraujoch can be socked in for days at a time even when Interlaken is sunny, so building flexibility into your itinerary for high-elevation excursions is genuinely important. Check the Jungfrau webcam the evening before any planned ascent.

Bern

Bern operates an integrated tram and bus network through Bernmobil, with the main station (Bahnhof) at the western edge of the Old Town as the central hub. The compact city means most visits centre on walking — the entire UNESCO Old Town is 1.6 km long and easily covered on foot. The Bern Ticket included with most hotels gives free public transport for the duration of your stay. SBB intercity trains connect Bern frequently to every major Swiss city; the Swiss Travel Pass covers all SBB and Bernmobil services.

Walkability: Bern is one of the most walkable capital cities in the world — the entire UNESCO Old Town is 1.6 km long and 400 m wide, easily walked end to end in 25 minutes. Streets are largely pedestrianised in the Old Town with only delivery vehicles and trams. The arcades shelter you in any weather. Even reaching the Rosengarten viewpoint or Paul Klee Centre is a 15-30 minute walk for those wanting it.

Interlaken

Interlaken is a model of Swiss public transport connectivity. Two train stations — Interlaken West (trains to Bern and Thun) and Interlaken Ost (trains to Grindelwald, Lauterbrunnen, and the Jungfrau region) — sit at opposite ends of the Höheweg. The Swiss Travel Pass covers SBB intercity trains, most PostBus routes, the lake boats, and gives 25% off most mountain railways. It does NOT cover the Jungfraujoch surcharge (CHF 45 from the Eigergletscher junction). A car is unnecessary and often counterproductive — Grindelwald, Wengen, and Mürren have limited or no car access.

Walkability: Interlaken town itself is easily walkable — Interlaken West to Interlaken Ost along the Höheweg takes about 25 minutes on foot. The Höhematte meadow, main shops, restaurants, and the Aare river are all within a 10-15 minute walk of either station. Mountain villages like Grindelwald and Lauterbrunnen are reached entirely by rail and cable car from the valley.
