Pohorje
The Lovrenc lakes, dark windows in the peat bog
- Lakes
- About 20, some pond-sized
- Origin
- About 8,000 years ago
- Peat
- Up to 3 m thick
The Lovrenc lakes are around twenty dark, almost black pools in the Pohorje peat bog, in the municipality of Lovrenc na Pohorju. You visit them on wooden boardwalks leading to a viewing tower, never setting foot on the peat, which is up to 3 m thick. RTV Slovenia says they formed about 8,000 years ago and that the area is the largest wetland in the country.
You can see the lakes on a short walk, but I'd give them a quiet morning. I'd climb the tower to see the pools from above and stay on the boardwalks, because the bog is very fragile, then carry on walking across the Pohorje.
If you only read this
Full read: 2 min
- About 20 dark lakes in a Pohorje peat bog.
- Formed about 8,000 years ago.
- Slovenia's largest wetland, according to RTV.
- Seen from boardwalks and a wooden tower.
Is it worth it?
Yes
A short, unusual stop: black pools in a peat bog, seen from boardwalks and a tower. Worth it if you're walking the Pohorje anyway; not a trip on its own.
My key points
Before you go to Pohorje, this
-
01 Most beautiful
Almost black water
All the lakes are very dark, almost black, because of the peat beneath them, according to RTV Slovenia.
-
02 Worth the splurge
Endangered dragonflies
Two endangered dragonflies live in the bog, the moorland hawker and the white-faced darter, along with rare plants such as the Rannoch-rush.
-
03 My tip
Up the tower
The best view is from the wooden tower beside the highest pool, according to the tourist board, and panels beneath it explain the plants and wildlife.
-
04 Getting there
The rest of the range
The lakes sit high on Pohorje, Slovenia's only silicate range, with forests, ski resorts and other bogs.

What I would book
Visiting: boardwalks and tower
In the middle of the bog stands a wooden tower, and the tourist board says the best views are from the one beside the highest pool. Panels beneath the tower explain the plants and animals. Boardwalks link the tower with the woods, and you walk along them without ever entering the bog.
Above all, this is a protected nature reserve. RTV reports that when scientists found one of the boardwalks was damaging the habitat, it was closed and the vegetation left to recover. The authorities realised the bog will only stay special if it’s left alone, with as little interference as possible.
What the Lovrenc lakes are
RTV Slovenia explains that the Lovrenc moors are the largest wetland in Slovenia and one of the southernmost in Europe. They formed about 8,000 years ago, when rainwater was trapped above an impermeable layer of silicate rock, the same rock that makes Pohorje Slovenia’s only silicate range, according to the tourist board. Peat gradually built up on top, reaching 3 m in places.
There are about 20 small lakes. Some are no bigger than ponds, and all have very dark, almost black water because of the peat beneath them. Around them stretch gentle meadows and moss-covered wetland.
Rare plants and dragonflies
What really sets the bog apart is its life. RTV mentions plants that grow only in habitats like this, such as the Rannoch-rush and a rare subspecies of crowberry, plus two endangered dragonflies, the moorland hawker and the white-faced darter. The tourist board speaks of peat bog pools and beds of rare plants visible from the path. Elsewhere on Pohorje it mentions the carnivorous sundew, and notes that the range has many protected areas within the Natura 2000 network. Pohorje Regional Park, of around 52 km², protects the range’s alpine bogs along with its plains and primeval forest.
Peat also has a gentler use on the range. At the Terme Zreče spa, on the Rogla side, the tourist board suggests a peat bath, which it describes as a natural source of health and well-being.

When to go and how long
I’d pair the lakes with a walk on Pohorje on a summer or autumn day. The tower and boardwalks don’t take long, but the place makes you want to linger.
What’s nearby on the Pohorje
The lakes lie in the municipality of Lovrenc na Pohorju, which SURS puts at 2,981 people on 1 January 2026. From here Pohorje carries on towards Rogla, with its treetop walk, and towards Maribor, with the Mariborsko Pohorje ski resort.
So you do not lose the morning at the ticket office, browse tickets and tours in Lovrenc Lakes on GetYourGuide.

True or false?
0/3 Pick before you peek.

The lakes' water is dark because of the peat.
See the answer
True. The peat beneath gives them their almost black colour.
-
The lakes formed about 8,000 years ago.
See the answer

Frequently asked questions
How many lakes are there?
About 20, according to RTV Slovenia. Some are no bigger than ponds, and all of them have dark, almost black water.
How did they form?
About 8,000 years ago, when rainwater was trapped above an impermeable layer of silicate rock. Peat built up on top, up to 3 m thick.
Can you walk on the bog?
No. You follow wooden boardwalks linking the viewing tower with the woods, and never enter the marsh. One walkway that was damaging the habitat was closed so the vegetation could recover.
What plants and animals live here?
RTV Slovenia mentions the Rannoch-rush, a rare subspecies of crowberry and two endangered dragonflies, the moorland hawker and the white-faced darter.
Where are they?
High on Pohorje, in north-east Slovenia, in the municipality of Lovrenc na Pohorju, west of Maribor.
