Blue Cave

Luštica Peninsula, near Herceg Novi, Montenegro

---

The Blue Cave, located on the Luštica Peninsula near Herceg Novi, Montenegro, is a stunning sea cave famous for its electric blue glow created by sunlight reflecting off the sandy seabed and entering the cave through its large opening.

This natural phenomenon illuminates the cave’s interior with vibrant blue hues, making it one of the most breathtaking and surreal spots along the Montenegrin coast. The cave has two openings, allowing boats to enter, and it features a spacious, vaulted interior where visitors can often swim in crystal-clear waters.

Accessible only by boat, usually from Herceg Novi, Kotor, or Tivat, the Blue Cave is a popular destination especially during late morning to early afternoon when the blue light is most vivid. Its unique natural beauty combined with the dramatic setting under high cliffs makes it a must-see attraction for nature lovers and travelers to Montenegro.
