(CNN) — Are you ski or snowboard obsessed? Do you crave an endless winter?
If ski lifts closing at the end of the season is a time to mourn, you'll be keen to scout out those summer spots.
Summer skiing, on dazzling-white glaciers high above lush green valleys, can help feed that addiction without flying to the southern hemisphere.
Here's seven venues where you can stave off those winter withdrawal symptoms.
Hintertux is the only ski resort in Austria open 365 days a year and boasts extensive high-altitude summer skiing and snowboarding at the head of the Ziller valley south east of Innsbruck.
With up to 10 lifts and a possible 18 kilometers of slopes above 3,000m, Hintertux offers a range of skiing for all levels below the Olperer peak at 3,478 meters.
The quality of the snow means the Hintertux glacier is a favorite spot for international ski teams to train in the off season.
The Betterpark Hintertux is one of the highest freestyle parks in Austria at 3,200m with terrain for all levels from April to early June and from mid-September to December.
Les 2 Alpes, France

The 120-hectare glacier, 70 kilometers from Grenoble, is one of Europe's biggest summer spots offering slopes from 2,900 meters to almost 3,600 meters on the Dome de la Lauze.
The ski area contains 11 runs (1 red, 9 blue, 1 green) plus a snowpark, accessed by 17 lifts. It is open for skiing and boarding from 7am to 1230pm from June 24 to September 2.
Les 2 Alpes is set to be connected to nearby Alpe d'Huez by an 18-minute gondola by the 2021, taking the winter ski area to a whopping 475 kilometers of piste.
What could be better for the obsessed snowsports fan than a slide around the glacier in the morning, followed by a dip in the Tignes lake in the afternoon?
Tignes' summer skiing area is perched high up on the slopes of the Grande Motte (3,656 meters), reached by a high-speed underground funicular and then cable car up to a high point of 3,456 meters.
There are 20 kilometers of varied runs open from the end of June until early August with views over to the giant Grand Casse in the heart of the Vanoise National Park.
Acrobats with energy to burn can launch themselves on ski, board, back or bike down water ramps into the lake.

The 13 blue and red runs are reached by the Klein Matterhorn cable car, which rises to the high point of the Matterhorn glacier paradise ski area -- shared with Cervinia in Italy -- at 3,883m.
There is also a terrain park with half pipe, kickers and rails for gravity-challenging snowsports fans.
Zermatt's glacier skiing area, more than two kilometers above the historic town, is a favorite summer training spot for racers and international ski teams.
Hiking, mountain-biking and climbing surrounded by some of the Alps' highest peaks make Zermatt a popular summer destination.
In winter the area combines with Cervinia in Italy to offer 360 kilometers of connected trails.
