Once tried, summer Alpinism is never forgotten. The unspoilt Tarentaise is an authentic experience with warm temperatures and epic scenery. Clear mountain streams and waterfalls tumble down the mountains, verdant meadows accompany tranquil lakes and surging rivers cut through the valleys.
Large areas of the valley are protected for its stunning flora and fauna. Sure-footed ibex and chamois rule the craggy peaks, marmots bask in meadows richly carpeted with wild flowers, while eagles soar above the Vanoise National Park - one of Europe’s oldest and largest protected areas.
As the winter snow melts away, the cols (mountain passes) become accessible giving the valley a completely different dynamic. You can take a delightful, quick drive over le col du Petit St Bernard into Italy's Aosta Valley for breakfast or lunch, and enjoy probably the best views of Mont Blanc.
The working villages flourish in the summer as the main resort towns shut down. Most have a fête - a traditional summer celebration with rather fewer cream teas than the English version and quite a lot more red wine. Sample the local cheeses or génépi liqueur flavoured with wild flowers.
Hike or bike on the extensive trails in the Vanoise National Park or go kayaking or white-water rafting on the Isère River. Climb, ride horses, play tennis or golf. Or if you can’t wait for the first snowfall the glacier at Tignes is skiable all year.
The Tarentaise is a great place for children with lots of safe swimming and adventure parks. A favourite with our kids is Plan d' Eau near Bellentre (between Bourg St Maurice and Aime), which they've nicknamed the Wonderful Place. It's a majestic Alpine lake surrounded by fabulous scenery where the the family can swim, play, sunbathe and barbeque.
In July the Tour de France makes its gruelling way through the mountains of the valley. Test your mettle against the professional riders by following the route or actually compete in one of the many organised races that take place in the valley during summer.
