Plješevica (Bosnia and Herzegovina)

Weather…

Plješevica is a prominent mountain range in northwestern Bosnia and Herzegovina, forming much of the natural border with Croatia. The highest peak on the Bosnian side is Gola Plješevica, at 1,648 meters, which towers over the city of Bihać. Geologically, the mountain belongs to the Dinarides and consists mainly of limestone, resulting in numerous caves and karst springs in the Una valley. Historically, Plješevica gained worldwide fame during the Cold War with the construction of the Željava Air Base, one of Europe's largest underground military facilities, carved directly into the mountain. The range is characterized by dense mixed forests, home to brown bears, wolves, and lynx. Due to its strategic border location, the mountain was a military restricted area for a long time, which helped preserve its pristine nature. Today, Plješevica is a popular destination for hikers and nature enthusiasts, who can enjoy vast panoramic views over the Lika plateau in Croatia and the Una valley in Bosnia. The harsh climatic conditions ensure that the peaks remain snow-covered well into spring.

📋 Practical info

🧭
Getting there
The mountain can be approached from the Bihać area, with some trails starting near the lower border villages. Exploring the exterior of the former Željava airbase requires navigating specific access roads.
📅
Best season
Hiking the long mountain range is best attempted from late spring to early autumn to avoid harsh snowstorms. Exploring the lower base areas is possible year-round, though roads may be unmaintained in deep winter.
⛰️
Terrain & paths
The range features dense forests transitioning into exposed, rocky alpine environments along the border ridge. The area surrounding the former underground airbase includes abandoned concrete infrastructure.
🎒
What to bring
Comprehensive hiking gear and reliable navigation tools are strictly necessary for the long mountain range. If observing the old airbase from the outside, durable footwear and a strong flashlight are recommended.
🅿️
Parking
Informal parking is usually found at the edge of access roads or in nearby villages before the terrain steepens. Visitors to the Željava area often leave cars on the large abandoned tarmac strips, near the border.
⚠️
Safety
The border zone requires extreme caution due to the potential presence of unexploded ordnance from past conflicts. Visitors must strictly stay on well-marked paths and adhere to all border patrol regulations.
⏱️
Time needed
Hiking to the prominent peaks of the range demands a strenuous full-day commitment of 7 to 9 hours. A visit focusing solely on viewing the exterior of the former underground airbase typically lasts two to three hours.
