The Blue Cave on Bisevo Island

Blue Grotto of Bisevo

View Croatia in a larger map 

The tiny islet of Bisevo is only 5 nautical miles southwest of Komiza on Vis Island.Covering 6 sq km, it would hardly be noticed at all except for its remarkable Blue Grotto (Modra Spilja) that strongly suggests the famous Grotto of Capri.

Of about ten caves scattered around Bisevo's coast, the Blue Cave is the most outstanding. Between 11am and noon on a sunny calm day, rays of the sun passing through an underwater opening illuminate the cave with a luminous blue light while objects beneath the surface shimmer in silver and pink. The effect is eerie and unearthly especially if you're lucky enough to see it when the cave is uncrowded which it certainly won't be if you come in July and August.

Although long known to fishermen, the cave has only been accessible to the non-diving public since 1884 when an entrance was formed by blasting a hole in the rock.

Other Sights

Although clearly the most outstanding sight, the Blue Grotto is one of several points of interest on Bisevo. If you have your own boat you can explore about nine other caves scattered around the coast. Originally populated by Benedictine monks, the island still houses the 11th-century Benedictine Church of St Silvester. And there are some wonderful swimming coves tucked away along the sea, some of which are sandy.

Getting to Bisevo

In addition to the summer excursion boats that link Komiza and Bisevo, there is a regular passenger ferry service that runs all year, leaving Komiza at 8am and returning from Porat on Bisevo at 3.30pm. (See the schedule). To visit the Blue Cave, disembark at Mezoporat where small boats can run you out to the nearby cave. The visit is short but stunning.

There are also agencies that run fast boat excursions for a visit to the Blue Grotto. Regular excursions run from Split, Omis, Komiza and Trogir, sometimes combined with a visit to other islands. Click here for the full menu of tours.

For a more private experience, hire a boat in Komiza and motor out yourself. Afterwards you can boat around the tiny island and stop to bathe in hidden coves. Take a fishing rod because the waters are teeming with fish.
