Colmar to Varenna: Scenic Alpine Drive Guide

The route from Colmar to Varenna spans approximately 450 kilometers (280 miles) and takes around 4.5 to 5.5 hours of pure driving time. The journey begins in the Alsatian wine country and ends on the eastern shore of Lake Como, crossing through three countries: France, Switzerland, and Italy. The most efficient path uses the A35 (France), then the A2/A13 (Switzerland) through Basel and the Gotthard region, eventually connecting to the A2/SS340 (Italy) towards Lake Como.

A little-known historical fact: the route roughly follows the old Via Francigena pilgrimage path, and near the Gotthard Pass, you can see remnants of the 19th-century coach roads. The highest point of the drive is the Gotthard Tunnel (Switzerland), at over 1,100 meters, but the real scenic gem is the Tremola road (the old pass), a cobblestone hairpin route that is a UNESCO World Heritage tentative site. For drivers, the most surprising quirk is the need for a Swiss motorway vignette (40 CHF for one year), available at border gas stations. Plan to buy it at the Basel border crossing, otherwise you risk a fine.

Family-Friendly and Pet-Friendly Stops

For children, the Swiss Transport Museum in Lucerne (detour 30 min) is excellent, but if time is tight, the Swissminiatur miniature park in Melide (right on the A2, just before the Italian border) is a hit. It features mini models of Swiss landmarks and a playground. Pets are welcome on leash. For dog walks, there are rest areas along the A2 with fenced dog runs, especially at the Wassen Nord service area (km 120). Also, the lakeside of Altdorf has a grassy dog park.

• Culinary pitstop: Ristorante Crotto del Lupo (just off the SS340 near Bellagio) serves traditional pasta with lake fish. In Switzerland, the RestStop Motel in Göschenen (before the tunnel) offers self-service buffet with vegan options.
• Fatigue management: After 2.5 hours, stop at the Gotthard service area (near the tunnel) – it has a designated sleeping cabin for drivers (paid, around 15 CHF for 30 minutes). Alternatively, pull off at the Altdorf rest area (free, 3-hour parking limit). To keep alert, the descent into Italy is winding; take a 10-minute break at the Bellinzona vista point.

Hidden Off-Route Gems

Just 5 minutes off the A2 near Bellinzona lies Castelgrande, a medieval castle with free entry to the courtyards. In France, the abandoned village of Hunawihr (off the A35) is a fortified church and vineyard, rarely crowded. Another spot: the ghost town of Rüeggisingen (Switzerland) near Wassen – an abandoned hamlet at the foot of a mountain, reachable via a 2-minute gravel road from the main highway.

Climatic Conditions and Aesthetics

The best time for this drive is late spring (May) or early autumn (September) when the weather is stable. In summer, the Gotthard area can have storms, but the Lake Como region is often sunny. For a sunset view, aim to be on the SS340 near Varenna around 18:00 – the sun sets over the lake from the western shore. Conversely, the early morning light in the Alps is spectacular; if you leave Colmar at 7 AM, you will catch the sunrise over the Rhine.

Geographical Shifts

The drive passes through three distinct zones. First, Alsace: vineyards and flat plains, with rows of half-timbered houses. Then the Jura hills and the Rhine valley near Basel, a transition to the Swiss Plateau. The most dramatic shift occurs at the Gotthard massif: from lush green valleys around Altdorf, you dive into the tunnel and emerge into the warmer, Mediterranean-like Ticino region with palm trees and chestnut forests.

• Notable scenic viewpoint: The village of Andermatt (just before the tunnel) offers views of the Urseren valley. For a detour, take the old Tremola road (exit at Airolo) – a 15-minute drive on cobblestone with 180-degree turns, perfect for photos.
• UNESCO sites along the route: Alsace wine route (Colmar is part of it, but the road itself passes near the Mont Vully vineyards; the city of Bern (old town) is a 1-hour detour north of the A2. However, the most relevant is the Rhaetian Railway in the Albula/Bernina landscapes (a detour of 2 hours). Strictly on route, the Gotthard railroad line (part of the Swiss Alps Jungfrau-Aletsch UNESCO) is visible near Wassen.

Local Commerce and Delicacies

In Alsace, buy kougelhopf or Alsatian wine (Riesling) from roadside stalls near Eguisheim. In Switzerland, look for Ticinese salami or Bündner Nusstorte (pastry) at service stations near Bellinzona. In Italy, the area around Varenna is known for olive oil and cheese (formaggio di capra). There is a weekly market every Tuesday in Bellinzona (just 20 minutes from the exit) selling local honey and cured meats.

Fuel and Route Economics

Fuel costs vary significantly across the three countries. In France (Colmar area), diesel is around €1.80/L, while in Switzerland it's about 1.80 CHF/L (€1.85). Italy is cheaper at €1.70/L. Combined with the hilly terrain, expect average consumption of 7-8 L/100 km for a modern sedan. The total fuel cost for the trip is approximately €60-70. Fuel stations are plentiful, but in Switzerland, many close by 8 PM in rural areas. The A2 motorway has service areas every 30 km, but they often charge a premium (up to +20% for fuel). A tip: fill up before entering the Gotthard area to avoid the highest prices.

• France: Colmar (A35) – cheap supermarkets like Leclerc fuel stations.
• Switzerland: After Basel, stop at Landquart or Erstfeld service areas (Coop or Shell) for decent prices.
• Italy: Before entering Varenna, fuel up at Bellinzona or Lugano (Italian side) as Lake Como stations are scarce and expensive.

Tolls and Vignettes

France: The A35 from Colmar to Basel is toll-free (it's a divided highway, but not autoroute at parts). Switzerland: A vignette (40 CHF) is mandatory for the A2 and all Swiss motorways, valid for 14 months. Purchase at the border (Basel) or at Swiss post offices. Italy: The A2 from Chiasso to Milan has tolls: expect €10-15 for the 50 km stretch to Como. The SS340 (lakeside road) is toll-free.

Road Quality and Safety

The A35 in France is well-maintained but has many roundabouts near Colmar. The Swiss A2 is excellent, but watch for speed cameras (fixed and mobile) in tunnels. The Gotthard Tunnel is 17 km long, well-lit, but prone to congestion (up to 30 minutes wait) on weekends. After the tunnel, the descent into Italy on the A2 is steep; use engine braking. The SS340 around Lake Como is narrow, with some guardrail gaps; take it slow. For night driving, the Gotthard corridor is well-lit, but the SS340 has poor illumination, so dimer your lights.
