Why is the Zelenci Nature Reserve so Special to Visit?
The 14-hectare Zelenci Nature Reserve has been officially protected since 1992. At its heart lies the three-meter-deep, emerald-green Lake Zelenci, located on the far western edge of the Drni Marsh. The reserve stretches nearly 1,200 meters in length and 150 meters in width. It lies right at the border with Triglav National Park.
What makes this wetland so special is its vibrant color palette and its striking landscape features. In a relatively small area, you’ll find the upper part of a river basin, lakes fed by bubbling underwater springs, crystal-clear “water windows,” and winding channels flowing through the lower marsh.
One of Zelenci’s most remarkable characteristics is the porous chalk at the bottom of the lake. It allows groundwater to rise through in the form of tiny “volcanoes,” creating gentle, constant bubbling on the water’s surface.
Thanks to these springs, the water stays a steady 5–6°C year-round, giving Zelenci its surreal turquoise color that visitors instantly fall in love with.
Sava River sources in Zelenci, as the longest Slovenian river and as the second spring of a brook called Nadiža, which sources near a mountain cottage in Tamar Valley. Nadiža River, along with other torrential streams in the Planica Valley, flows below the water-permeable gravelly surface.
A short wooden boardwalk leads you through the protected wetland, where you’ll hear birds, frogs, and rustling reeds. From the little viewing tower, the scenery opens up into one of the most photogenic views in the region, with the Špik mountain range rising behind the water.
Now that you know what makes Zelenci Nature Reserve so unique, let’s look at the best time to visit.
Best Time to Visit
Nothing beats Zelenci at sunrise. The light is soft, the water completely calm, and you often get the whole place to yourself. Late afternoon is also beautiful—but expect more visitors. Timing really does shape the experience.

The best thing ever. I took my old boss to experience Slovenia in one day. And boy I am happy I chose Altitude Activities to do so. Our tour guide Jerry was awesome, funny and you could just see he knows what he is doing. We went to the canyon of Jermanka and even though there is a drop almost 45m high we felt extremely safe. Overall highly suggest going canyoning with Altitude Activities
