The only descent down the river Soča where you don't just stay on its surface but dive underneath!

You will feel the power of the water and the many rapids on the river Soča as the hydrospeed allows you to safely slide over even the largest of rapids. A thick neoprene wetsuit will protect you from the glacial water of the emerald beauty and keep you pleasantly warm. Clothed like this you will gleefully welcome the waves splashing into you. These thrills can only be experienced if you go hydrospeeding!/p>

Lie down on the hydrospeed, hold it firmly with both hands, and use the flippers to... propel yourself wherever you wish! You will be accompanied by one of our friendly, highly-trained, experienced, and licensed guides, who will paddle alongside you in a kayak to ensure a safe descent (and hand you a spare flipper if needed!).
