The Blue Cave near Kotor is a natural sea cave formed in the limestone cliffs of the Lustica Peninsula. Its remarkable light effect is created when sunlight penetrates the underwater entrance and refracts upwards through the water, illuminating the cave interior in an intense, shifting blue glow. The effect changes throughout the day as the sun moves, and our captain always times the visit to catch it at its most dramatic.

Beyond the Blue Cave, the coastline around Kotor is dotted with smaller grottos, underwater arches, and rocky overhangs that reward exploration by snorkel and by eye. Our cave tour includes time at multiple locations, giving you a comprehensive introduction to the geological wonders hidden along this remarkable stretch of the Adriatic coast.
