French alps in may: where to go and what to do

May is one of the most underrated months to visit the French Alps. Spring is fully established in the valleys and at lower altitudes — terraces are open, wildflowers are appearing, lake temperatures are climbing towards swimwable — while the high mountains above 2,000 m still hold their winter snowpack. It is a month of extraordinary contrasts: you can wake up to glaciers above Chamonix and swim in Lac d’Aiguebelette by the afternoon. Prices are well below the summer peak, the mountains are quiet and the light is exceptional. Here is how to make the most of the French Alps in May.

Weather in the French Alps in May

May is generally mild across the French Alps. Expect afternoon temperatures of around 20°C in the major valley towns — Annecy, Chambéry, Bourg-Saint-Maurice — rising to 23°C in Grenoble and slightly lower in the Southern Alps towns of Gap and Briançon (around 17–20°C). At altitude, temperatures are cooler: around 16°C at Valloire (1,460 m) and 14°C at Bessans (1,700 m).

May is also one of the wetter months in the Northern Alps — rainfall is higher than in summer, particularly in the pre-Alpine ranges (Évian averages 107 mm, Chambéry 104 mm). Rain tends to come in short, sharp showers rather than sustained grey days, and the Southern Alps are significantly drier. If weather reliability is important to you, the Southern Alps (Hautes-Alpes, Haute-Provence) are a more reliable May choice than the Northern Alps.

Lake towns and valley cities in May

The towns and lakes at the foot of the Alps are at their best in May: Annecy, Aix-les-Bains, Évian, Chambéry, Gap and Digne all offer a different pace from the mountain resorts — more relaxed, more local, with good restaurants and access to nature without the summer crowds. Lake water temperatures are still cool in early May (around 15–16°C) but can reach 18–20°C on the surface by late May in a good year. Swimming is possible, though most visitors prefer stand-up paddleboarding, kayaking and lake boat trips at this stage of the season.

Annecy is particularly good in May: the old town is in bloom, the cycle path around the lake (40 km, largely traffic-free) is perfect in the spring light and the crowds of summer have not yet arrived. Aix-les-Bains on Lac du Bourget has a Riviera quality in May — boat trips to the Abbaye d’Hautecombe, spa treatments and the lakeside casino gardens make it an excellent base. Lake Geneva (Lac Léman) shore villages — Yvoire, Évian, Thonon — are charming in late May as the lakeside gardens come into full flower.

Where to stay by the lake in May

• Lac du Bourget: the Hôtel l’Incomparable (5-star, lake view, Tresserve) is exceptional. For a more affordable option, La Maison des Pêcheurs is a charming small hotel on stilts above the lake.
• Annecy: the Pelican (new hotel, lake view, old town) or the Rivage & Spa (4-star, modern lakeside spa hotel) are both excellent May choices.
• Lake Geneva shore: the Hôtel du Pré de la Cure at Yvoire — pool, spa, facing the medieval village — is one of the most pleasant May stops on the French Riviera of the Alps.
• Chambéry: the Château de Candie (beautiful historic property on the outskirts) or the Petit Hôtel Confidentiel (frequently cited as one of France’s finest small 5-stars).
• Embrun / Lac de Serre-Ponçon: La Robeyere — a beautiful converted manor house turned 4-star hotel at the gateway to Serre-Ponçon lake.

Mountain villages in May

There is no bad season in the mountains — and May in the Alpine villages has a particular quality that is hard to find at any other time of year. The ski resort crowds are gone, the summer tourists have not yet arrived and the villages are at their most authentic: bakers, artisan workshops, a few good restaurants and genuine local life. The landscape is dynamic — crocuses, anemones, narcissi and orchids appearing week by week, chamois and ibex visible on the slopes and the first marmots emerging from their burrows.

One practical note: below 1,500 m, the landscape is fully green and spring-like. Above 1,500 m in early May, the trees may not yet be in leaf — it can feel wintry in the villages despite mild temperatures. Our recommendation for early May: stay below 1,200 m for the full spring experience. By late May, all restrictions apply — the mountain passes are opening one by one and the Alps are taking on their summer character.

The best village bases for May: Chamonix (1,000 m — exceptional setting, year-round energy, glacier access), Saint-Gervais (850 m — spa town at the foot of Mont Blanc, good hotels open year-round), Les Gets (1,172 m — charming Haute-Savoie village, good early season hiking), Samoëns, Le Grand-Bornand, La Clusaz and Serre Chevalier in the Southern Alps.

Where to stay in a mountain village in May

• Chamonix: the Rocky Pop (colourful, fun 4-star), Heliopic (4-star at the foot of the Aiguille du Midi cable car) and Le Faucigny (charming boutique hotel in the town centre) are all open year-round. See our full Chamonix hotel guide.
• Saint-Gervais: le Saint Gervais (new 4-star) or Hôtel des 2 Gares (recently renovated, pool).
• Les Gets: Chalet-Hôtel la Marmotte — 4-star chalet with pool in the village centre at 1,172 m, one of the best May options in Haute-Savoie.
• Serre Chevalier: le Monêtier — excellent year-round hotel adjacent to the thermal spa, Southern Alps sunshine.

Hiking, trekking and wild camping in May

May marks the opening of the hiking season in the French Alps — but with important altitude limitations. Forget the great high-altitude routes (Tour du Mont Blanc, GR5 through the Vanoise) for now: above 2,000 m, high passes are still blocked by deep névés and spring snow makes walking exhausting and potentially dangerous without specialist equipment. Focus on the pre-Alpine massifs and south-facing slopes for the best May hiking:

• Le Vercors: the vast limestone plateaux are paradise for spring trekking and first wild camps of the year — excellent multi-day routes well below the snow line, extraordinary scenery.
• La Chartreuse and Les Bauges: ideal for day walks through forests returning to vivid green. Close to Grenoble and Chambéry respectively — easy to combine with a lake town base.
• Southern Alps — Luberon, Verdon, Baronnies provençales: fully dry, fully snow-free and at their most beautiful in May. The Baronnies provençales around Buis-les-Baronnies offer some of the finest spring hiking in France, with lavender fields not yet in bloom but the landscape extraordinarily clear. The Mont Ventoux south-facing route opens to cyclists from late April.

Wild camping in May

May offers the first real wild camping opportunities of the year in the Alps. Nights are still cool and you will need proper cold-weather sleeping equipment — but the rewards are considerable. Around 2,000 m (accessible on foot in May in most pre-Alpine massifs), the combination of thawing lakes, returning wildlife and near-total solitude creates a wilderness experience that disappears in July when the summer crowds arrive. The marmots are out, the ibex are visible on the ridges and the sunrises are exceptional. Always check the avalanche bulletin before camping in mountain terrain in May.

Exploring the Alps by campervan in May

May is an excellent month to explore the Alps by campervan or motorhome. Campsites are open but not yet full, mountain roads are clear (the high passes open through the month), and the flexibility to follow the weather is particularly valuable in the changeable May climate. A week combining Chamonix (one night facing Mont Blanc), the Annecy lakeside, a pass into the Vanoise or the Italian Val d’Aoste and the shores of Serre-Ponçon lake makes for a classic May road trip. Campervan rental platforms such as Yescapa operate across the French Alps.

Head south for guaranteed sunshine

For those who want warmth and reliable sunshine above all else, the Southern Alps and their Provençal foothills are the answer in May. The Gorges du Verdon, Buis-les-Baronnies, Vaison-la-Romaine and the Drôme Provençale are superb: rock climbing on the Baronnies limestone, cycling the Mont Ventoux (accessible from the south from late April), walking through olive groves and lavender fields, and evenings on terrace restaurants with views of snow-capped peaks. Temperatures reach 22–25°C regularly in this zone in May.

Good bases: Nyons, Vaison-la-Romaine or Buis-les-Baronnies. Our favourite: Le Clos Saint Michel & Spa — a beautiful wellness retreat at the foot of Mont Ventoux.

Skiing in May in the French Alps

A handful of resorts remain open in early May with substantial terrain still available:

• Val Thorens, Tignes, Val d’Isère, Chamonix and Orelle — typically open until the first days of May with full high-altitude domains. Conditions are often excellent: firm morning snow, spring sunshine and virtually no queues.
• Les Deux Alpes — the glacier runs remain open throughout May for summer skiing preparation, making it the only resort with continuous May skiing beyond early month.

For ski touring enthusiasts, May is actually one of the best months of the year across the entire Alpine range: firm early-morning snow on high-altitude routes, long days and exceptional conditions on classic routes around Chamonix, Saint-Gervais and the Vanoise. Contact the guides’ offices in Chamonix or Saint-Gervais for organised ski touring excursions — this is exactly what the bureaux des guides specialise in at this time of year.
