Best Low-Traffic Cycling Climbs in Soča Valley
The Soča Valley is one of the best road cycling regions in Slovenia—but during peak season, some of the main roads can get busy.
Fortunately, the valley is full of hidden climbs and quiet side roads where traffic is minimal and the riding experience is exceptional.
Whether you start in Bovec, Kobarid, or Tolmin, you can access some incredible low-traffic climbs.
Here are three of the best options for riders looking to escape the crowds.
1. Secret Trenta Climb – Hidden Gem with No Traffic
This is one of the best-kept secrets in the upper Soča Valley.
Starting from Bovec, the route heads into the Trenta Valley before turning off the main road near the village of Soča onto a quiet road along the river.
After a short steep kicker, the road becomes smooth and peaceful, surrounded by untouched alpine nature.
Since the road is a dead end, traffic is almost nonexistent.
The climb itself is challenging but very rewarding, making it a perfect ride for hot summer days when you want to avoid crowds.

The route passes waterfalls and wild alpine terrain before climbing steadily toward the Italian border.
The ascent toward Sella Carnizza is consistent and enjoyable, with very little traffic compared to more famous climbs in the region.
It’s an ideal option for a half-day ride with a solid climbing challenge in a peaceful environment.

3. Kolovrat Climb – Legendary Ridge Above Kobarid
Located above Kobarid, the Kolovrat climb is one of the most iconic ascents in the Soča Valley and a regular feature in the Giro d’Italia.
The route starts in Kobarid and quickly turns into a steep and demanding climb through small villages and forested sections.
With gradients reaching around 10%, it is a true test for strong riders.
At the top, you are rewarded with panoramic views and a World War I open-air museum along the ridge.
Despite its reputation, much of the climb takes place on relatively quiet roads, making it a great choice for those seeking a serious challenge without heavy traffic.
