Beautifully shot footage, filmed on May 1, of a group of extreme sports enthusiasts kayaking on the "emerald waters" of the Soca river in Slovenia.

The filmer later wrote online: "The emerald waters of the Soča and its tributaries evoke feelings of flowing excitement in a rapidly growing number of admirers.

"White water enthusiasts float down the river in large rubber boats, with the kayakers braving the tumbling rapids even more numerous."

"Join in as a group of friends paddles down this beautiful river," he continued.
