Espace Diamant, Ski area in Savoie and Haute-Savoie, France.

Espace Diamant links the ski slopes of Les Saisies, Crest-Voland Cohennoz, Notre-Dame-de-Bellecombe, Flumet–Saint-Nicolas-la-Chapelle and Praz-sur-Arly into one area between the Beaufortain massif and the Val d'Arly. It counts 157 runs and 81 lifts, with altitudes given as 1,000 to 2,069 m in French sources and 910 to 2,069 m in English ones.

Espace Diamant was created in 2005 by merging two earlier ski areas: Espace Cristal, formed in 1984 from Hauteluce-Les Saisies and Crest-Voland Cohennoz, and Espace Val d'Arly, formed in 1973 from Flumet, Notre-Dame-de-Bellecombe and Praz-sur-Arly. The linked area spans the Beaufortain massif and the Val d'Arly in Savoie and Haute-Savoie.

The five villages here display traditional Savoyard architecture with wooden chalets and stone buildings that show the area's mountain heritage. This style shapes how the villages look and how people have lived in the region for generations.

The area links five resorts on foot and by lift, from Les Saisies and Hauteluce to Crest-Voland, Cohennoz, Notre-Dame-de-Bellecombe, Flumet, Saint-Nicolas-la-Chapelle and Praz-sur-Arly. Slopes run between 910 and 2,069 m, with 32 green, 58 blue, 47 red and 10 black runs. A separate Nordic domain at Crest-Voland Cohennoz–Les Saisies covers 80 km of cross-country trails.

Espace Diamant was formed in 2005 by merging two older ski areas: Espace Cristal, created in 1984 around Les Saisies and Crest-Voland Cohennoz, and Espace Val d'Arly, created in 1973 around Flumet, Notre-Dame-de-Bellecombe and Praz-sur-Arly. The linked slopes let skiers cross between the Savoie and Haute-Savoie departments without removing their skis.
