Méribel Les Allues is a ski resort that was developed adjacent to the traditional hamlet of Morel, with its centre situated at about 1400 metres above sea level. It was founded by a Scotsman, Major Peter Lindsay, who was looking for a new site for winter sports away from the ski resorts of Austria and Germany, because of the growing strength of the Nazi regime. In 1936, he visited the town of Les Allues for the first time. He then imagined how the town could become a ski resort. Firstly, he decided to create a property company in order to develop finances strong enough to build the resort. In 1938, the first lift was placed above Les Allues. A year later, he began the construction of the first chalets and hotels in the hamlet of Méribel. Three years later, the war would stop the development of the resort, but when it was over, development continued. Now a Colonel, Peter Lindsay used specialised architects, Paul Grillo (Grand Prix de Rome in 1937) and his partner Christian Durupt, so that all buildings would be in harmony with the Savoyard style, using wood and stone for the walls, with slanted slate roofs. In 1950, the Burgin-Saulire gondola was built to link the resort to Courchevel. Lindsay's family continue to hold a financial stake in the resort. Lindsay's ashes and those of his wife are scattered on the Burgin mountain.
Since 1971, it has been possible to ski the interlinked valleys using a single ski pass. Thus, Les Trois Vallées is the largest connected ski area in the world which is linked solely by ski lifts and slopes. It claims to have about 600 km (370 mi) of ski slopes, resulting in 18.5 km² of groomed runs, while an independent expert measured about 493 km. In addition, there are 120 km for cross-country skiing. Les Trois Vallées has 183 ski lifts, which can transport 260,000 skiers per hour. Other equipment owned by the operating companies include 2,300 snow cannons and 73 snow grooming machines operated by 160 snow groomers who work in shifts during the night. Other employees in the area include 424 ski patrollers and 3,000 ski instructors.
