This is a great and unique video of our canyoning activity in Bannau Brycheiniog (Brecon beacons) in Wales, UK. One of the groups took their own video camera on the activity. The camera man, when jumping off one of the big waterfalls, drops the camera. However it continues to film on it’s way to the bottom of the pool.
Not only that you can then watch as our instructor dives down to retrieve the camera. You can see this from 2.25 onwards
