If the ascent from Roselend Cormelet to Bourg St. Maurice is great, the descent to Beaufort is amazing. The spectacular views are go on and on until you reach Roselend Dam. The greenery there is so intense and the sky is so blue that it'll make your eyes hurt. The dam was built between 1956 and 1962 by the company EDF and its turquoise blue waters remain in their background a village submerged by them and that his memory was built the church that exists today, exact replica of the previous one. There's a small restaurant there that you can eat at and enjoy the view of the reservoir, the church and the green meadows with cows that are waiting to be milked.
