A loop around Mont Blanc from Geneva takes in three countries in two or three days: Chamonix in France, about 90 km and 1 h 15 from Geneva Airport, Courmayeur in Italy, about 107 km away via the Mont Blanc Tunnel, then Aosta and the Great St Bernard back into Switzerland and along Lake Geneva. It is one of the most varied short road trips in the Alps, and a chauffeur from AirportsTransfers.ch handles tunnels, passes and borders while you look up at the highest summit in Western Europe from every side.
- Route: Geneva, Chamonix, Mont Blanc Tunnel, Courmayeur, Aosta, Great St Bernard, Martigny, Lake Geneva
- Countries: Switzerland, France and Italy, with two border crossings
- Length: two days at a brisk pace, three days for a relaxed loop
- Season: the Great St Bernard pass road opens in summer; the tunnel beneath it is open all year
- Highlights: Aiguille du Midi, Mer de Glace, Skyway Monte Bianco, Roman Aosta, the hospice
Day 1: Geneva to Chamonix
The first leg is short. The motorway follows the Arve valley from Geneva, crossing the border into France, and climbs past Sallanches, where on clear days Mont Blanc suddenly fills the windscreen. Arriving in Chamonix mid-morning leaves time for the town's two classic excursions. The Aiguille du Midi cable car rises in two stages to a rocky needle facing the summit of Mont Blanc, with terraces and a glass room suspended above the void; go early, when the air is clearest, and take warm clothes even in summer. Alternatively, the Montenvers rack railway climbs to the Mer de Glace, France's longest glacier, where stairs lead down towards an ice cave carved each year into the glacier. Spend the evening in Chamonix's lively centre, where mountaineers, skiers and visitors mingle, and stay the night.
Day 2: through the tunnel to Courmayeur and Aosta
In the morning, your chauffeur drives the few minutes to the Mont Blanc Tunnel, which passes beneath the massif into Italy. You emerge at Entrèves, just above Courmayeur, on the sunny southern side of the mountain. From here, the Skyway Monte Bianco cable car climbs towards Punta Helbronner, offering a different view of the same peaks you saw from Chamonix the previous day, now framed by Italian glaciers. Courmayeur's pedestrian street is ideal for an espresso before continuing down the Aosta Valley, past castles on rocky spurs, to Aosta itself. The town's Roman walls, the Arch of Augustus and the high facade of the Roman theatre make for an easy afternoon stroll, and lunch is a chance to try Fontina-based dishes and local wines. Stay the night in Aosta or a nearby country hotel to make the loop a relaxed three days.
Day 3: the Great St Bernard and back to Lake Geneva
From Aosta, the road climbs north towards the Great St Bernard, one of the oldest crossings of the Alps, used since Roman times. In summer, take the pass road to the top, where the hospice founded in the eleventh century still welcomes travellers beside a small mountain lake on the Swiss-Italian border. The canons of the hospice made the St Bernard dog famous, and dogs are still associated with the pass, with a museum devoted to them in Martigny. Outside the summer months, the road tunnel beneath the pass is used instead.
The descent leads down the Val d'Entremont to Martigny, in the Rhône valley, where the Fondation Pierre Gianadda's exhibitions and sculpture park are worth a stop. From there it is a straightforward drive along the Rhône to Lake Geneva, with an optional pause at the Château de Chillon or in Montreux, about 91 km from Geneva Airport, before returning to Geneva by evening.
- Two-day version: Chamonix, then tunnel, Courmayeur, Great St Bernard and home on day two
- Three-day version: night in Chamonix, night in Aosta, return via Martigny and the lake
- Reverse direction: start with the lake and the pass, finish in Chamonix
Practical tips for the loop
Carry identity documents for both border crossings and euros for France and Italy. Weather is the key variable: the high cable cars depend on clear skies and calm winds, so keep a flexible plan and swap days if needed. In winter, the loop still works using the tunnels, with snow chains carried, but the Great St Bernard pass road is closed. Pack layers, since the temperature drops sharply at the top of the cable cars, and sunglasses for the glare from snow and ice. If you plan to ride the Aiguille du Midi and the Skyway, check that both are operating on your dates, as each closes for annual maintenance.
