Hydrospeed

Hydrospeed on the Soča River – Pure adrenaline, direct contact with the water

Are you a confident swimmer who loves a good dose of adventure? Then Hydrospeed is the river sport made for you.

Born in France as a way of swimming through rapids, Hydrospeed has quickly become popular across Europe for the unique, thrilling experience it offers. You lie on a specially designed float, hold on to the handles, and steer using flippers on your feet – feeling every pulse of the water beneath you as you ride the rapids head-on.

The Soča River, especially in the stretch between the majestic Boka Waterfall and the historic Napoleon Bridge in Kobarid, is one of the most spectacular places in Europe to try Hydrospeed. Turquoise pools, wild currents, and big rocks create the perfect playground for this sport.

A full-immersion experience You’ll wear a reinforced wetsuit for full protection, plus flippers and a float that shields your chest and face. No previous training or course is needed – just strong swimming skills and a love for the water.

We use only the best foam or inflatable floats – lightweight, unsinkable, safe, and far superior to the old-style plastic ones. They offer maximum performance, agility, and comfort, so you can enjoy the river to the fullest.

Small groups, maximum safety Each group has no more than 5 participants and is always led by expert guides, carefully selected for both their safety standards and their ability to make every moment fun and unforgettable.

Our location – in the heart of the adventure We’re based in Trnovo ob Soči, surrounded by nature and right in the center of the most scenic river stretches. That means less time on transfers and more time in the water. After your descent, you’ll be back at your car in just a few minutes.

You’ll also find a café, minimarket, changing rooms, and free private parking on-site.
