Zelengora Lakes: What to Expect on a Guided Zelengora Tour

Zelengora Lakes: What to Expect on a Guided Zelengora Tour

Zelengora is the green, lake-studded heart of Sutjeska National Park, and when we take you on a Zelengora tour you should expect gentle highland walking, glacial lakes called “mountain eyes,” and a rough jeep ride to reach them. This guide explains exactly what a guided Zelengora tour with us looks like: which Zelengora lakes we actually visit (Donje Bare, Gornje Bare and Orlovacko Lake are the big three), how hard the Zelengora hiking is, what to bring, and the best season to come.

What Zelengora actually is

Zelengora (“Green Mountain”) is a huge mountain massif in the west of Sutjeska National Park, in Foca municipality, Republika Srpska, Bosnia and Herzegovina. It spreads across three municipalities (Foca, Kalinovik and Gacko) and is all rolling grassy plateaus, spruce and beech forest, shepherd settlements (katuns) and open meadows full of wildflowers and blueberries.This is the soft side of the park: no dramatic cliffs, just green ridges and water. It is the complete opposite of the rugged Maglic and Volujak side across the Sutjeska canyon. The whole national park covers 16,052 hectares, and Zelengora is its largest single feature.The highest peak is Bregoc, at 2,014 metres (you will also see 2,015 or 2,017 m quoted). Note: the “1,875 m” figure sometimes given for Bregoc is wrong. Other Zelengora peaks include Kozje Strane (2,013 m), Orlovaca (1,969 m) and Ugljesin vrh (about 1,858 m). Lelija (2,032 m) is a neighbouring massif connected to Zelengora, not strictly part of it.Zelengora’s glacial lakes were carved out during the last Ice Age. Most sources describe eight glacial lakes plus one artificial one, though you will see the number given as seven, eight, nine or even more depending on who is counting and which small ponds get included. The named lakes are Orlovacko, Stirinsko, Kotlanicko, Jugovo (also called Borilovacko, the artificial one), Crno (Black), Bijelo (White), Kladopoljsko, and Donje Bare and Gornje Bare. The park protects over 2,600 plant species, plus one of Europe’s most vital populations of brown bear, wolf and Balkan chamois, along with deer, eagles and trout in the lakes.

The main Zelengora lakes we take you to

Not every lake gets a tour. Some sit hours from any road with no marked trail. These are the popular Zelengora lakes that operators here actually run tours to.

Donje Bare

Donje Bare (Donja Bara) is the classic Zelengora day-tour lake and the one closest to Tjentiste. It sits at around 1,490 metres (some sources say up to 1,517 m), about 200 m long, 140 m wide and up to 4 metres deep, with forest on one side and open meadow on the other. There is a rebuilt mountain hut right by the water (Planinarski dom Donje Bare) that you can rent, and a fresh spring behind it. From the parking area it is a short, easy walk to the lake and on to the Boric viewpoint (about 1,680 m), where the whole Sutjeska canyon, Maglic, Volujak and even Durmitor open up in front of you.

Gornje Bare

Gornje Bare (Gornja Bara) sits higher, at around 1,550 metres, roughly 1.5 to 2 km northwest of Donje Bare. The trail between the two is a pleasant forest and meadow walk, and most family tours link Donje Bare, Boric and Gornje Bare into one easy loop of a few hours. Gornje Bare is shallower and ringed with marsh flora, sitting under the peaks of the Tovarnica ridge.

Orlovacko Lake

Orlovacko Lake (Orlovacko jezero) is the most famous and most visited lake on Zelengora, and for many the most beautiful. It sits at about 1,438 metres under the peaks of Orlovac, Orlovaca and Stog, roughly 250 to 350 m long, covering about 3.5 hectares with a maximum depth of about 5.5 metres. It holds brown trout and stocked rainbow trout. There is a national park mountain hut here (two bedrooms, living room with fireplace, kitchen, bathroom) plus a large campsite with capacity for around 130 places. Because it is fed by a big spring and is relatively deep, this is the lake where swimming is genuinely pleasant on a hot summer day. Orlovacko is reached from the Kalinovik/Cemerno side, not directly from Tjentiste. Multi-day and longer day tours often add Stirinsko (the largest and shallowest lake, highest on the mountain), Kotlanicko (deepest, striking blue, with a medieval stecci necropolis nearby) and Jugovo (the small artificial lake, 1 km from Orlovacko). These four (Stirinsko, Kotlanicko, Jugovo, Orlovacko) are the classic central-Zelengora lakes loop.

What a typical Zelengora tour day looks like

Almost every Zelengora tour is a jeep-plus-hike combination, because the trailheads sit on rough gravel (macadam) roads that a normal car should not attempt. A typical day: morning start from camp, drive to Tjentiste, then transfer into 4×4 vehicles for the bumpy climb (around an hour on dust and stones) up onto the mountain. We park at the trailhead, then walk.Formats vary. The most popular is a full-day family tour to Donje Bare, Boric and Gornje Bare, with an easy two-to-three-hour walk and a picnic or hut lunch. More active guests choose the central lakes hike (Stirinsko, Kotlanicko, Jugovo, Orlovacko) or a summit day up Bregoc, a relaxed 1h40 to 2h ascent from Orlovacko that is not technical. There are also multi-day traverses linking the Bare lakes, Bregoc, Ugljesin vrh and the Orlovacko group, sleeping in huts or camping by a lake. Full-day Zelengora tours in this area typically run 8 to 10 hours door to door and start from around €65 to €70 per person, with jeep transport, guiding and usually lunch included.Zelengora combines naturally with the park’s other highlights: the Prijevor plateau, Maglic, heart-shaped Trnovacko Lake and the Perucica primeval forest are all reachable on separate days from the same base.

Difficulty, fitness and who it suits

Zelengora is one of the easiest serious mountains in Bosnia to enjoy. The Bare loop suits families with children and anyone of moderate fitness. The central lakes and Bregoc need more stamina but no scrambling. This is not high-alpine terrain, but you are at 1,450 to 2,000 metres, so weather changes fast: we have had sun, rain and cold wind in a single afternoon, and storms build on summer afternoons.You do not legally need a licensed guide to walk on Zelengora, unlike Perucica, which can only be entered with a certified guide. Zelengora is free-access. In practice, though, we strongly recommend going guided: the access roads are confusing and rough, and away from the Bare area many central-Zelengora trails are poorly marked or unmarked.

What to bring

Bring proper hiking boots with ankle support, layers including a windproof jacket, sun protection, at least 1.5 to 2 litres of water, and snacks. The spring water at the huts and by the lakes is cold and drinkable, but the lake water itself is not for drinking. Pack a swimsuit in summer for Orlovacko, cash for the park fee, and expect little to no mobile signal on the mountain. Watch for ticks in long grass, and remember this is bear and wolf country (encounters are rare, and your guide knows the drill).

Best season for Zelengora hiking

The season runs roughly June to October. July and August are the most reliable, with warm days, open huts, swimmable lakes and wild blueberries everywhere. Spring means lingering snow and muddy trails; the huts and tour services shut down for winter, when Zelengora is under deep snow. For photography, the best light is early morning and late afternoon over the meadows and lakes.

FAQ

How many lakes does Zelengora have?

Most sources say eight glacial lakes plus one artificial (Jugovo/Borilovacko). You will also see the count given as seven or nine. The best known are Orlovacko, Donje Bare, Gornje Bare, Stirinsko and Kotlanicko.

Are Orlovacko and Gornje Bare the same lake?

No. This is a common mix-up. Orlovacko Lake is in central Zelengora, reached from the Kalinovik side. Gornje Bare is a separate, smaller lake on the Tovarnica ridge near Donje Bare, reached from Tjentiste. They are different lakes on different sides of the mountain.

Do you need a 4×4 for Zelengora?

Yes for the trailheads. The gravel roads from Tjentiste to Donje Bare and to the Orlovacko area are rough and best driven in a high-clearance 4×4, which is why our tours include jeep transport.

Is there an entrance fee?

Yes. Sutjeska National Park charges 10 KM (about €5) per person for the wider park area, which includes both the Zelengora/Donje Bare side and the Prijevor side. Bring cash.

Can you swim in the Zelengora lakes?

Yes, at your own risk. Orlovacko is the best for swimming. Many lakes are shallow, grassy and cold, so pleasant swimming depends on the lake and the day.

Do you need a guide?

Not legally, unlike Perucica. But roads and trails are rough and often unmarked, so a guided tour is the practical way to see the lakes.
