There are truly some natural wonders in this area and it is worth taking the trip to Peisey-Nancroix any time of the year. Positioned at the end of a high-altitude valley, the scenery is spectacular and the sense of calm is palpable. There are plunging waterfalls (frozen in the winter), pretty hamlets and rugged slopes. Whether you choose to cross-country ski, hike, snow-shoe, dog-sled or ride a horse-drawn sleigh, the area fully deserves a visit.
If you walk up from Plan Peisey you can reach the Notre Dame de Vernettes chapel, which sits alone on the side of the mountain. The interior is small but magnificently painted and the local tourist office organises regular guided trips to see it. If you are an accomplished skier, it is possible to ski to the door although, because it is some way from the marked pistes, it can be easy to miss.
Another more recent man-made attraction is the Vanoise Express cable car which spans the valley. It only takes a few minutes to traverse the gap but it is quite a vertiginous feat of engineering. In the winter, expert snow artists are known to create vast murals on the fields below the gondola, giving you something to look at through the glass floor.
