The Balkans has some of the best national parks in Europe. I have not found another region where you get this kind of variety in such a small area — turquoise lakes in Croatia, limestone peaks in Montenegro, ancient forests in Bosnia, and alpine meadows in Bulgaria. You can go from sea level to 2,500 meters in a single day.
I have hiked through most of these parks over the past few years. Some are crowded (Plitvice, I am looking at you), others you will have almost to yourself. What follows are the 15 parks worth planning a trip around — the ones that left an impression on me. Entry fees and opening months are current as of 2026. Always check official sites before you go.

1. Plitvice Lakes National Park, Croatia
Plitvice Lakes is the most famous park in the Balkans for good reason. Sixteen terraced lakes connected by waterfalls. Wooden walkways let you walk right over the water. The water changes color depending on the light — emerald, turquoise, deep blue.
- Entry fee: €30–€40 (seasonal; highest in summer, cheapest in spring and fall)
- Best time: May–June (less crowds, full waterfalls) or September–October (autumn colors, fewer people)
- Tip: Arrive before 8 AM. The park lets in a limited number of visitors per day and sells out by midday in July and August.
2. Krka National Park, Croatia
Krka is Plitvice's more relaxed cousin. Fewer crowds, and you can actually swim near the main waterfall, Skradinski Buk. The park follows the Krka River through travertine cascades and pools.
- Entry fee: €15–€25 (seasonal)
- Best time: June–September (for swimming)
- Tip: The swimming area near Skradinski Buk closes at 4 PM. Get there early.
3. Durmitor National Park, Montenegro
Durmitor is a UNESCO World Heritage site in northern Montenegro. The park centers on a massif with 18 glacial lakes, the most famous being Crno Jezero (Black Lake). The Tara River Canyon — the second deepest canyon in the world — borders the park.
- Entry fee: €5 per person
- Best time: June–September for hiking; December–March for skiing
- Tip: The hike from Black Lake to the Peak of Bobotov Kuk (the highest point) takes about 6 hours round trip. You do not need climbing gear.
4. Biogradska Gora National Park, Montenegro
Biogradska Gora is one of Europe's last remaining primeval forests. The centerpiece is Biogradsko Lake, a glacial lake you can walk around in about an hour. The forest has trees over 400 years old.
- Entry fee: €5
- Best time: May–October
- Tip: Camp at the lake. There are designated spots and the sound of the forest at night is something else.
5. Lovćen National Park, Montenegro
Lovćen is the mountain that overlooks Kotor Bay. The drive from Kotor up the serpentine road is an experience in itself — 25 switchbacks. At the top, the Njegoš Mausoleum gives you a 360-degree view of the bay and the Adriatic.
- Entry fee: €3 for the park, €8 for the mausoleum
- Best time: April–October
- Tip: Do the drive at sunset. The light on the bay is unreal.
6. Tara National Park, Serbia
Tara sits in western Serbia along the Drina River. Thick pine forests, limestone cliffs, and the Drina River Canyon — the third deepest in the world after Tara Canyon and the Grand Canyon. The park is home to the endemic Pančić spruce.
- Entry fee: Free entry; small fees for specific attractions
- Best time: May–October
- Tip: Visit the Banjska Stena viewpoint. The view of the Drina Canyon is worth the short hike.
7. Sutjeska National Park, Bosnia and Herzegovina
Sutjeska is Bosnia's oldest national park and one of its wildest. It contains Perućica, one of the last primeval forests in Europe, and Maglić Mountain (2,386 m), the highest in the country. Skakavac waterfall drops 75 meters inside the park.
- Entry fee: ~€5 per person
- Best time: June–September
- Tip: The hike to Maglić summit is serious — start at 5 AM, bring plenty of water, and hire a guide unless you know the terrain.
8. Una National Park, Bosnia and Herzegovina
Una is named after the Una River, known for its clear green water and travertine waterfalls. Štrbački Buk is the biggest waterfall in the park — a 24-meter cascade that you can feel from 50 meters away.
- Entry fee: ~€5 for the park; rafting trips €25–€40
- Best time: May–September
- Tip: Raft the Una. It is some of the best Class II–III rafting in the Balkans.
9. Pelister National Park, North Macedonia
Pelister is the oldest national park in North Macedonia, centered on Mount Pelister (2,601 m). The park has two glacial lakes called the Mountain Eyes — Big Lake and Small Lake. The endemic Macedonian pine (molika) grows here.

- Entry fee: Free; chairlift to the lakes costs ~15 leva round trip

- Tip: Do the Seven Rila Lakes cirque hike — it takes about 4 hours and hits all seven lakes.
12. Triglav National Park, Slovenia
Triglav is Slovenia's only national park, named after the country's highest peak. It covers the Julian Alps and includes Lake Bohinj, the Soča River valley, and some of the best hiking in the Balkans.
- Entry fee: Free; parking fees apply
- Best time: July–September for hiking; year-round for valley visits
- Tip: You do not need to summit Triglav to enjoy the park. The valley hikes — like the one from Bohinj to Savica waterfall — are just as good.
13. Mavrovo National Park, North Macedonia
Mavrovo is the largest national park in North Macedonia. It surrounds Mavrovo Lake and includes Mount Korab (2,764 m), the highest peak in both North Macedonia and Albania. The park has a partially submerged church that emerges when the water level drops.

- Tip: Drive to the top or do the 6-hour traverse from Ohrid-side to Prespa-side. Both lakes are visible from the summit.
15. Fruška Gora National Park, Serbia

- Entry fee: Free
- Best time: April–October
- Tip: Combine a monastery visit (I recommend Hopovo and Krušedol) with a wine tasting at one of the local wineries.

Which National Park Should You Visit First?
If you have never been to the Balkans: Plitvice. It is popular for legitimate reasons. If you want fewer people and bigger mountains: go to Durmitor or Sutjeska. If you are on a budget and want variety: North Macedonia's parks (Pelister, Mavrovo, Galičica) are all free and give you a different landscape each time. If you are passing through Belgrade: Fruška Gora is a solid afternoon escape.
These 15 parks cover every type of Balkan landscape — coast, karst, alpine, river, and forest. Pick the one that matches the kind of trip you want, and go.
