Krokar, the forest people left alone

- Kočevje
The Krokar primeval forest is an ancient beech forest in the south of Kočevje, above the Kolpa valley, on UNESCO's World Heritage List since 2017 as part of Europe's primeval beech forests, a property of 93 components in 18 countries. You don't walk into it: you see it from the Borovec trail, overlooking the Kolpa, alone or with a local guide. May, with the narcissi, is the best time.
Krokar isn't a park with a ticket office; it's a forest left to itself. I'd walk the Borovec trail in May, slowly and quietly, and to understand what I was seeing I'd go with a Kočevsko guide.

01 Most beautiful
Daffodils under the beeches in May
The tourist board recommends the Borovec trail in May, when daffodils bloom beneath the trees. The route is waymarked with a daffodil symbol.
-
02 Worth the splurge
A guided walk with a forest picnic
Visit Kočevsko runs a trip from Kočevska Reka, taking in Slovenia's thickest walnut tree, the Borovec trail and a picnic of local produce, for groups of 2 to 10.

03 My tip
Head down to the Kolpa canyon
From the Borovec trail you can drop down into the Kolpa canyon, says the tourist board, so wear walking boots and, in summer, pack a swimsuit.

04 Getting there
More beech forests on the same list
Slovenia has two parts in this UNESCO property, Krokar and Snežnik-Ždrocle. Both belong to the Primeval Beech Forests of Europe.

What I would book for Kočevje
What the Krokar forest is
Krokar lies at the southern end of Kočevje, above the Kolpa valley, and in 2017 it joined the World Heritage List, as one of the sites in a UNESCO listing of ancient and primeval beech forests spread across the Carpathians and other parts of Europe. UNESCO describes it as a serial property of 93 components across 18 countries, showing how beech spread across Europe from a few refuges in the Alps, Carpathians, Dinarides, Mediterranean and Pyrenees after the last Ice Age. Slovenia contributes two pieces, Krokar and Snežnik-Ždrocle. It’s one of the country’s five World Heritage properties, which I cover on my page about UNESCO sites in Slovenia.
The tourist board explains that Krokar is one of six surviving patches of primeval forest in the Kočevje area, where about 90% of the land is wooded.
Seeing it: the Borovec trail
From the Borovec trail, the Borovška pešpot, which skirts the forest. It starts in the village of Borovec pri Kočevski Reki and gives you the Kolpa valley on one side and the primeval forest on the other. The tourist board recommends it for family walks, waymarked with a daffodil, and suggests going in May, when daffodils bloom beneath the trees. From the trail you can also drop down to the canyon of the Kolpa river.
For me it’s a walk to take slowly and in silence. There are no big viewing platforms or visitor facilities, and that’s exactly the point. Bring water and food, because Borovec is a small village, and remember that this is bear country, which is another good reason to stick to the marked path.
With a guide from Kočevska Reka
If you’d rather have it explained, Visit Kočevsko runs a guided outing for groups of 2 to 10. It starts in Kočevska Reka, the valley’s main village, home to Slovenia’s thickest walnut tree and a man-made lake that, together with the surrounding forest, is a forest reserve where white-tailed eagles nest. The village was founded in the 14th century by farmers from Germany and Tyrol, and after the war it lay inside a closed zone for decades, which is why the landscape survived so well. You then walk the Borovec trail and finish with a picnic of local produce in the woods.

What else to do nearby
Krokar fits into a day in the Kočevje area alongside an outing to see bears in Slovenia, which have their largest population here, or an afternoon on the Kolpa. Kostel Castle is in the same valley.
If you are short on time, see the best tours in Krokar primeval forest and pick one that fits your day.
