Val d'Isère and Tignes sit at the dead end of the Tarentaise valley, and for a long time that was the whole story. Val d'Isère's first hotel opened in 1888, the road over the Col de l'Iseran opened in 1937, and the Société des Téléphériques de Val d'Isère was founded in 1938 with a plan for 34 km of slopes that could be skied without taking the same lift twice. Tignes started with a single tow in 1936. In 1952 the old village was drowned by the Chevril dam, and the resort was rebuilt on the heights above at 2,100 m. The two ski areas were joined by lifts, sold for decades as the Espace Killy, and are now marketed as one: Tignes - Val d'Isère.
It's a place for skiing, not strolling. The area runs from 1,550 m to a 3,456 m cable car, has two glaciers and opens in November for a season that ends in early May. Val d'Isère is a stone-and-wood village that has kept a village's shape; Tignes is a purpose-built modern resort at 2,100 m that doesn't pretend otherwise. Five days is enough to ski each sector once. The plan is pitched at confident intermediates and strong skiers, who get the Face de Bellevarde, the black runs on Solaise and the glacier. Beginners and first-week skiers should ski the same days at their own level: the green areas and free lifts in both resorts are real, but the Face, the Tunnel and the high glacier can wait for another year.
The plan runs one sector a day. Days one to three start in Val d'Isère (Solaise, Bellevarde and the Face, Le Fornet and the Pisaillas glacier), and days four and five cross to Tignes (the Grande Motte glacier and the lake, then the lower villages and the dam). Choose the base before you book: sleep in Val d'Isère for the first three nights, then move to Tignes for the last two, because the free shuttle doesn't reach Val Claret or Le Lac and the lifts, your only free way back, stop for the day before the evening starts. Staying in Val d'Isère all week works, but days four and five become day trips with an early finish and no evenings in Tignes. Take the whole-area pass either way: a single-resort day is only 8 EUR cheaper. It starts on a Sunday, because Saturday is changeover day and the roads are worst, and Val d'Isère itself suggests Sunday-to-Sunday stays. The first clean start is Sunday 10 January 2027, after Christmas and the World Cup weekend of 12-13 December, and it finishes before Tignes's Mountain Shaker festival (17-22 January).
