Overview

Interlaken to St. Moritz is about 4 hr 30 min of driving without stops. The fastest sensible line is Route 6 east from Interlaken via Brienz and Meiringen, Route 11 over the Susten Pass (2,224 m) to Wassen, a short run on the A2 to Göschenen and Andermatt, Route 19 over the Oberalp Pass (2,044 m) through Disentis and the Surselva to Chur, then Route 3 over the Julier Pass (2,284 m) via Lenzerheide, Tiefencastel, Bivio and Silvaplana to St. Moritz. Below: what the drive actually costs you in tolls and time, where it is worth stopping, and what to know before you set off.

Before you go: Two of the three passes on this line are summer-only: the Susten and the Oberalp are normally open roughly June to October and closed by snow the rest of the year, while the Julier is cleared year-round. Outside that window the 250 km scenic line does not exist and you have to take the motorway detour via Lucerne, Zurich and Chur — about 293 km.

Driving time and distance

How to plan stops on the Interlaken to St. Moritz drive

• Start with live navigation and add only stops that sit naturally on the corridor you are actually taking.
• For short transfers, one coffee stop or one viewpoint is usually enough; trying to collect multiple towns often turns the day into parking and backtracking.
• Check parking rules, restricted-traffic zones, and seasonal road conditions before committing to a detour.
• If weather is poor or you are arriving late, head straight to your base and save viewpoints for a clearer day.

Use official local tourism and parking information to finalize any detours for your travel date.

Where to stay if you split the drive

• Interlaken: Useful if your flight lands late and you want to start driving fresh the next morning.
• Mid-route overnight: Choose a town that truly sits near your live halfway point rather than forcing a scenic detour.
• St. Moritz: Best when the transfer is short enough that you can arrive early, park once, and explore on foot.

Road conditions and tips

• Swiss motorway vignette applies on motorways. Confirm if your rental includes it.
• Leave early on mountain driving days and keep offline maps available in weak-signal valleys.

When to drive this route

Late spring through early autumn is the easiest window for consistent scenic access. Winter is possible, but needs weather flexibility and stricter timing discipline.
