There has been an explosion in popularity in the last few years for camera drones, with professionals filming anything and everything from epic ski descents to aerial views of the mountains, incredible outdoor scenery, races and competitions.
Increasingly, these kinds of flying cameras are being used to capture people's holidays and outdoor experiences, with a lot of new users making impromptu flights in areas where they may not be sure of the risks or restrictions that might be in place, or in conditions where they may not be able to fully control the camera.
Accidents can happen, as ski racer Marcel Hirscher found out when he was almost taken out by a drone falling from the sky in Italy a few seasons ago. But it's not just accidents that drone pilots need to be aware of, it's things like being considerate of nature reserves, heavily built up areas, or in Val d'Isere - where rescue helicopters operate.
If you've got a drone and you're thinking about using it in Val d'Isere then you can find out below where you're allowed to and, more importantly, where you're not allowed to fly.
