Zelenci is a beautiful nature reserve just outside Kranjska Gora, known for its vibrant emerald-green spring that marks the source of the Sava Dolinka River. It’s an easy and scenic walk from the parking lot—perfect if you’re short on time but still want a peaceful nature stop. The boardwalk leads you through wetlands to a picture-perfect viewpoint, and there’s even a little café on site by the parking lot where you can grab a drink or snack.
