The Blue Grotto is one of the biggest draws on the island of Capri. It is a surreal experience. The peculiar iridescence of the water bathes the interior of the grotto with a serene light that is similar in color to a sapphire blue topaz. The Blue Grotto is 4 miles long and almost 2 miles wide with the highest point at 1,930 feet above sea level.

The main Blue Grotto cave, called the blue cathedral, extend many passages that lead to lesser chambers and other underground ravines. The good thing is that the island of Capri is full of wonderful ocean views that, more often than not, include that splendid crystal clear turquoise blue water for which the island is famous

The boats leave from between 9am and 5pm, weather permitting, from the tiny harbour of Weid iz-Zurrieq and cruise for about 30 minutes before reaching the caves.

All the boats traveling to The Blue Grotto enter under an immense arch into a 140ft high cave cut into the rock face. The system consists of six caves carved by years of relentless pounding by the sea, of which the Blue Grotto is the largest and most impressive. The water seems an impossible cobalt color as the sky reflects off the white sand bottom. The caves sparkle both with blue reflections of the sea and orange, purple and green of the various minerals present in the rocks.
