Mrežnica River, Built Around You
The Mrežnica is a gentle karst river close to Zagreb, known for its dozens of small travertine cascades — natural limestone barriers that step the river down through pools and drops, similar in character to Plitvice but on a smaller, more intimate scale. Clear, emerald-green water and mostly easy Class I–II rapids make it one of the more approachable rivers in Croatia to kayak, suited to first-timers and families as well as more experienced paddlers.
Rather than a single fixed itinerary, this is a starting point for a private trip built around how you actually want to see it: a half-day or full-day kayaking trip from Zagreb, or combined with a wider Karlovac-region visit. Tell us your dates and interests, and we'll plan the rest.

Fit the Mrežnica into your trip
A Mrežnica trip commonly takes one of a few shapes — we'll adapt any of these to your own dates and route:
- A half-day kayaking trip from Zagreb, focused on the river's travertine-cascade section
- Combined with a wider Karlovac-region visit, including the town's old fortifications
- A stop on the way to or from Plitvice Lakes, since both sit along the same route south from Zagreb
- Paired with another river activity, such as rafting on the Zrmanja or Cetina, for a multi-day water-focused trip
