The Blue Caves are a popular tourist destination on the Greek island of Zante, aka Zakynthos. Zante is one of the Ionian islands lying off the west coast of Greece.
Limestone covers about 50% of the island. There are no show caves on Zante, unlike the neighbouring island of Kefalonia, which has Drogarati Cave and Melissani Lake. However there are sea caves. These are formed in Upper Cretaceous limestone (100-60 million years) and occur in the Pre-Apulian or Pazos zone (see ref).
The Blue Caves are located on the northeast tip of the island, between Agios Nikolaos and Skinari Cape. They are generally visited during boat trips that include a visit to Shipwreck Bay, Navagio Bay
