Paddleboarding Paradise: Discovering Slovenia’s Soča Valley
The Soča Valley is a unique place in Slovenia, with its emerald water, world-class whitewater, and gorgeous mountain backdrops. Long a classic destination for whitewater kayakers, the Soča also deserves a place on your bucket list for stand-up paddleboarding! Andrej Trnkoczy, founder of Bovec Paddleboarding, offers an in-depth guide to the river’s different sections and shares how to make the most of a SUP trip in this remarkable valley.
I still remember the stares. When we first took our stand-up paddleboards onto the Soča River in the summer of 2020, locals thought we’d lost our minds. Paddleboarding was something you did on calm lakes, not on one of Europe’s most beautiful whitewater rivers. But we knew something they didn’t yet— this emerald paradise was about to become a world-class SUP destination.
« The Soča Valley offers some of the most diverse and stunning paddleboarding experiences in Europe. »
Fast forward to today, and the Soča Valley welcomes paddleboarders from every corner of the globe. What started as a handful of « crazy » pioneers has evolved into a thriving community of whitewater and flatwater enthusiasts who’ve discovered what we knew all along: the Soča Valley offers some of the most diverse and stunning paddleboarding experiences in Europe.
Why the Soča Valley?
The first thing that strikes every visitor is the color. The Soča River flows in an otherworldly shade of emerald green that seems almost artificial in its vibrancy. But it’s the purity that truly sets it apart—in the upper whitewater sections, the water is so pristine you can drink straight from the river. This isn’t marketing speak; it’s a reality that makes every paddle stroke feel like a privilege.

Within a short drive from Bovec, paddleboarders can experience adrenaline-pumping whitewater descents through alpine gorges, serene flatwater paddles on mirror-like lakes, night paddling under star-filled skies, and cross-border adventures into Italy and Austria. Whether you’re seeking your next whitewater challenge or a peaceful escape on calm waters, the Soča Valley delivers both—often in the same day.
Whitewater Adventures: Five Distinct Sections
The Soča offers five SUP-able sections, each with its own character and challenge level, flowing from upstream to downstream:
Velika Korita Soče to Kršovec Bridge is the furthest upstream section, an easy but quite shallow run with a technical detail in the middle at Bunkarji. Best tackled with higher water levels, this section offers a taste of the upper valley’s raw beauty.
Kršovec Gorge to Čezsoča (Zmukljica Section) runs a bit deeper but is still quite shallow, best with higher water levels. This is where the Koritnica River joins the Soča, adding dynamic character to the run.
Čezsoča to Boka Bridge is perfect for beginners. This more open section features wider turns and a forgiving nature, best runnable in medium to low water. It’s an ideal introduction to whitewater SUP with spectacular mountain views.
Serpenica 1 to Trnovo 1 (Trnovo Section) is where things get serious. This advanced, high-volume run is suitable only for experienced paddlers ready for technical whitewater challenges.
Kobarid to Kamno offers a longer, wide-open beginner-friendly section further from Bovec, with the option to extend to Tolmin for those wanting more time on the water.
One section is strictly off-limits: the Katarkt section is forbidden to all watercraft due to its extreme danger. Respect this restriction—it exists for good reason.
The Koritnica: A Hidden Gem
For those seeking something different, the Koritnica River offers a tight, technical challenge. This small river is characterized by narrow turns and little room for error. Best run in medium water conditions, the Koritnica rewards skilled paddlers with an intimate, adrenaline-filled experience through its confined channels.
Timing Your Adventure
The Soča’s character transforms dramatically with the seasons, offering different experiences for different skill levels. The paddling season runs from mid-March through the end of October, with the river closed to all watercraft during the winter months.

Spring (April-June) brings big water from snowmelt. This is the time for experienced paddleboarders seeking serious whitewater action. Higher flows create bigger waves, stronger currents, and bring upstream sections to life that are too shallow in summer.
Summer (July-September) offers lower, more forgiving flows ideal for newcomers to whitewater SUP. The river still delivers plenty of excitement without the intimidating power of spring runoff, and sections like Čezsoča to Boka shine during these months.
Throughout the season, expect water temperatures between 8-13°C (46-55°F), which is why proper gear is essential: helmet, wetsuit, neoprene shoes, and life jacket are all mandatory for safe paddling.
Flatwater Escapes
Most na Soči Lake: Turquoise Dreams
Most na Soči Lake is simply amazing. Renowned for its turquoise water—most vibrant in springtime when snow melts—this long stretch of flatwater offers peaceful paddling with the option to explore the Idrijca River, which joins the Soča at the lake.
But the real magic happens after dark. The night paddling experience is nothing short of magical. With lights illuminating the underwater world below your board while stars shine above your head, you get the sensation of floating on light itself. The turquoise color really pops with the lights, revealing fish gliding beneath you and the walls of the gorge stretching down into the depths.
Lago del Predil, Italy
Just 40 minutes from Bovec, across the Italian border, lies Lago del Predil. This majestic lake sits in the heart of the high Julian Alps, offering tranquil paddling far from tourist crowds. Surrounded by dramatic peaks, it’s the perfect escape for those seeking solitude and stunning mountain scenery.
Austrian Lakes
About an hour’s drive north, several Austrian lakes offer additional flatwater opportunities. Lake Faak is perhaps the most interesting, but there are many more to explore, each with its own alpine character and crystal-clear waters.
Safety First
Let me be direct: if you’re new to the Soča Valley or to whitewater paddleboarding, book a guided tour first. The river may look inviting, but it demands respect and local knowledge. Understanding the currents, reading the rapids, and knowing where hazards lurk can mean the difference between an incredible experience and a dangerous situation.
The Evolution Continues
« The emerald water flows year-round, the mountains stand eternal, and the paddle community continues to grow. All that’s missing is you. »
From those first uncertain paddle strokes in 2020 to today’s thriving international SUP community, the Soča Valley has proven itself as one of Europe’s premier paddleboarding destinations. What makes it truly special isn’t just the emerald water or the diverse terrain—it’s the way this place gets under your skin.
Whether you’re navigating technical whitewater through the Koritnica’s narrow channels, floating on light during a night paddle at Most na Soči, or simply drifting across Lago del Predil with the Julian Alps towering above, the Soča Valley offers moments that stay with you long after you’ve dried off.
The funny looks have been replaced by knowing nods from fellow paddlers. The question is no longer « why would you SUP here? » but rather « when can I come back? »
The Soča Valley is waiting. The emerald water flows year-round, the mountains stand eternal, and the paddle community continues to grow. All that’s missing is you.
