Tignes Les Brevieres has some lovely off-piste skiing which can be especially handy when it's a whiteout as you can pick and choose some lines in between the trees. From the top of the Aiguille Percee chairlift if you head to the right, there is some off-piste that you can tackle, but be warned you can get stranded at the bottom not knowing which way to go, so make sure you have a mountain guide with you or plan your route in advance extremely carefully.
There are also plenty of off-piste sections to slide down by the side of the marked runs and pistes, and normally from the lifts, you can spot the best off-piste snow next to the runs.
Tignes Le Lac
The off-piste skiing in Le Lac is not that vast, however, there is plenty of fun to be had on the side of the pistes and you are never short of finding some powder to play in. If you find yourself in Tignes Le Lac on a powder day then you can enjoy lots of the white stuff near the Chardonnet lift, Palafour lift and can then head over to the L'Aiguille Percee and Tignes Les Brevieres for the off-piste skiing there. Try under the Grand Huit lift for some fresh tracks after a snowfall.
Tignes Val Claret
Val Claret again does not have a huge amount of off-piste skiing routes but you can always stick to the side of the pistes and play in the deeper snow there.
If you head up the Tichot Chairlift and then up the Grattalau you can hike from the top of the Grattalau either going right or left and explore some of the off-piste drops from there. Coming down the Grande Motte to the left of the Double M there is a small bowl where some lovely soft powder can sometimes be found, just make sure you cut across high enough up so you don't have to walk up the other side of the bowl. Overall, the Grande Motte will have some soft fresh powder snow to the sides of the pistes and if you get up there first after a fresh snow dump you can make the first off-piste tracks.
Bellevarde (Tignes / Val d'Isere)
The Bellevarde side of the mountain has the most off-piste skiing to offer, with 3 particularly well known off-piste slopes. The Banana, this is a very large vertical drop. The snow here heats up early so aim to ski this section in the morning. Go down the start of the Face from the top of the Olympique cable car and at the first bend to the left, continue straight on past an obvious rock on the right hand side. The first slope is very easy and leads to a level area with rocks at the end. Go left of these rocks down to another level section before taking the slope right down to the bottom of Santons.
The Charvet Tour, this is the best-known off-piste run in Val. Because of its south-facing aspect however, there is a high risk of snow-sliding so be especially wary in the afternoon. Take the Grand Pré chairlift and at the top, carry on along the line of the lift before cutting in right at the large flat area. From here, the less experienced skiers can continue traversing to the right towards the far end of the bowl and then follow the bottom of the valley back to the left. Others may prefer to go straight down. Depending on the snow cover, you can take either bank of the Charvet stream towards the gorge, a narrow but lovely pitch. From here, follow the slight descent beside the river to the Manchet valley and ending up at the Manchet Express chairlift.
The Face du Charvet, here you can find lots of challenging slopes, which incur more avalanche risks, and more risk of taking the wrong route. Stay high in the traverse of the South face to avoid cliffs, the long traverse will lead to a wide couloir which will then take you back to the village. The ski down is full of long steep descents.
