Плава пећина (Plava pećina) is a sea cave located on the Lustica Peninsula. It is also called Plava Spilja or Blue Grotto. Like most blue caves it is accessible only by boat, numerous boat operators offer trips to the cave. The entrance is rather small, but big enough for the small boats to enter. Inside is a single huge chamber with 3-4 m deep seawater with the typical blue glow. Most boats allow the passenger to take a swim, for about 15 minutes.
The main Blue Cave has two entrances, the rear entrance is a little smaller. Also, there are numerous smaller caves along the cliff, so some call it the Blue Caves. The other caves are much smaller and the boats can not enter.
There are numerous beaches and harbours in the surroundings, so there are numerous operators. It's best to ask at the reception of your hotel to book a trip, some even offer transfer from the hotel. Unfortunately the popularity means that during high season the cave is quite crowded. Sometimes the boats have to wait outside until another boat leaves, and with too many boats swimming is not possible. Also, the blue light is a result of sunlight in the water, it makes not much sense to visit the cave on a rainy day.
There is obviously a fee for the boat trips, but the cave itself is free, so if you have your own boat or use a kajak, you may visit it on your own. The boats typically depart as soon as enough people. Working hours are between 10 and 16, because at other times is not enough sunlight. If there are too high waves, the boats are not able to enter, as the entrance is only about 4 m high. And the waves actually do not stop at the cave entrance, so there are waves inside which might make swimming a bit tricky. The shortest and cheapest trips are from the
