Appenzell to Sion: Alpine Road Trip Guide

Leaving Appenzell, the road climbs immediately from the rolling green hills of the Appenzell Alps, passing the iconic Mount Säntis (2502 m) on your left. The route roughly follows the A1 and A2 highways before cutting south through the Bernese Oberland. The total drive covers about 350 km and typically takes 4–4.5 hours without stops.

Did you know that the section between Interlaken and Meiringen passes through the historic Brünig Pass, where in 1799 the French and Austrians fought a bloody battle? The narrow roads here still demand attention.

The landscape shifts from the green, dairy-farming pastures of Appenzell to the crystalline lakes of Lucerne and Brienz. After Interlaken, the valley narrows as you enter the Upper Valais region, with vineyards terraced on steep slopes above the Rhone river. The final stretch into Sion passes through the Gorges du Trient, a dramatic limestone canyon.

UNESCO World Heritage Sites: The Old City of Bern (passing near) and the Swiss Alps Jungfrau-Aletsch region (short detour from Interlaken). Both are worth a brief stop.

• Appenzell: Visit the Appenzeller Schaukäserei (demonstration dairy) for cheese tasting.
• Lucerne: Chapel Bridge and Lion Monument.
• Brienz: Lakeside promenade and the Ballenberg Open-Air Museum.
• Interlaken: Höheweg with views of Eiger, Mönch, and Jungfrau.
• Lötschberg region: Kiental valley or the UNESCO-listed Aletsch Arena.
• Sion: Valère and Tourbillon castles.

For hidden gems, detour 5 minutes off the A8 at Lungern to see the old church of St. Gallus and the lake with crystal-clear water. Another off-route spot is the abandoned village near the Grimsel Hospiz.

Road quality is excellent on motorways but winding on passes (Brünig, Grimsel) with sharp bends. Night illumination is good on highways; on secondary roads, reduce speed due to animal crossings. Toll gates exist only for the Lötschberg tunnel (car: CHF 30 one way), but the old road over the pass is free and scenic.

For families: The Ballenberg Open-Air Museum (near Brienz) has interactive exhibits for children. In Interlaken, the Jungfrau Park (amusement park) offers rides. The Sion old town has a small train that kids love.

Pet-friendly: Many Swiss restaurants allow dogs on terraces. In Interlaken, Café de Paris has a dog-friendly area. Short dog walks: along Lake Brienz promenade or the vineyard paths near Sion.

Fatigue management: Rest zones with parking and benches are common. Recommended nap spots: the viewpoint at Brünig Pass (parking lot) or the Acheregg rest area (A2 near Lucerne) with a coffee kiosk.

• Safety tip: Always carry a reflective vest and warning triangle (mandatory by law).
• Road condition updates: Check local radio or via the Swiss mobile app "Via Suisse".
• Emergency contacts: 117 (police), 144 (ambulance), and 140 (roadside assistance).

The drive uses Swiss motorways (A1, A2, A8) and federal roads (e.g., Brünigstrasse). No tolls, but an annual vignette (CHF 40) is mandatory for motorways. Fuel stations are plentiful along the A1 and A2, but rare on the mountain pass roads.

Fuel costs average CHF 1.70/litre for petrol. A petrol car will use around 30 litres (CHF 51) for the whole trip. Efficient diesel can cut this to 22 litres (CHF 37). Consider filling up in Interlaken before the climb to the Grimsel or Susten passes.

• Major highways: A1/A2 until Spiez, then A8/E8 to Interlaken, then A6/E62 toward Sion via the Lötschberg tunnel.
• Alternative scenic route: Grassimstrasse through Brienz and Meiringen, then the Grimsel Pass (summer only).
• Parking: Sion has paid parking garages near the old town; free outskirts parking possible.
