Blue Cave Montenegro

Blue Cave in Montenegro is a must if you’re planning a trip to the coast – a natural wonder that should top your list! Tucked away at the edge of the Luštica Peninsula, this sea cave glows with otherworldly shades of electric blue, offering one of the most surreal swimming experiences in the Balkans.

This blog will guide you through everything you need to know before visiting the Blue Cave – from what makes it special to how to get there, and what to expect on a boat tour from Kotor.

What is the Blue Cave?

The Blue Cave (Plava Špilja) is a sea grotto carved by centuries of waves and wind. What makes it extraordinary is a natural light phenomenon: when the sun hits the water at the right angle (best around noon), it reflects off the sandy sea bottom, causing the entire interior of the cave to glow a vibrant neon blue. It’s like swimming inside a sapphire!

Where is the Blue Cave Located?

The cave is situated at the Luštica Peninsula, near the entrance of Boka Bay. It’s only accessible by boat, making the journey just as exciting as the destination. Most tours depart from coastal towns like Kotor, Tivat, or Herceg Novi.

Why Take a Blue Cave Tour from Kotor?

Kotor offers one of the most scenic launch points. As you cruise out of the old town harbor, you’ll pass ancient stone villages, emerald-green hills, and tranquil islets – all framed by the dramatic cliffs of Europe’s southernmost fjord.

A good boat tour isn’t just about getting to the Blue Cave – it’s about the full experience. The best tours combine adventure, history, and relaxation, and often include:

• Swimming inside the Blue Cave
  
• Sightseeing and swim stops
  
• A visit to Our Lady of the Rocks in Perast
  
• Time to explore the glamorous Porto Montenegro in Tivat
  
• Drinks or snacks on board, and more
  

What Is the Boat Trip Like?

Imagine gliding across mirror-like waters on a spacious boat, with a light breeze and endless sea views. Along the way, you’ll hear local legends, stop to swim in the middle of the bay, and marvel at natural formations and fortresses rising from the sea.

Your skipper will navigate narrow channels and submarine tunnels left over from Yugoslav naval history – an unexpected but fascinating addition to the trip.

Swimming in the Blue Cave

Once at the cave, your boat will anchor at its entrance. The cave’s entrance is wide enough for small boats, but we prefer our guests to swim in for the best experience.

The moment you dip beneath the surface, you’ll understand the name. The water is crystal clear, and the blue glow feels like it’s coming from another planet. The depth ranges from 3 to 5 meters – shallow enough for safe swimming, but deep enough to enjoy snorkeling.

Don’t worry if you’re not a confident swimmer – our boat offers life jackets, so even those who are not swimmers can soak in the magic.
