Melissani cave, the home of the Nymphs, welcomes thousands of people from all over the world each year. Well known for its unparalleled beauty, million of photos have been taken in this place. Melissani is a natural limestone karst cave, formed over millions of years ago. Evidence suggests that in ancient times the cave consisted of two chambers and was used as a place to worship Pan.
Discovered in 1951, it was first opened fpr the public in 1963. During the first exploration an ancient lamp, (now on display in the Archaeological Museum of Argostoli) was found there. The excavations of 1962 produced important relics of a former Minoan culture on Cephalonia. Oil lamps, plates and figures show the god Pan and several nymphs.
Once you enter this dreamy place, you cannot resist the picturesque scenery. The crystal blue water is irresistible and you imagine you are a part of Greek Mythology. Cheerful boatmen help you embark on the small boat, in order to take you the tour around the lake. They will also explain you this natural wonder and tell stories about that. You have the opportunity to see both chambers of the cavern, do a round trip in the first hall with the hole in the roof and see also the second chamber which has numerous big stalactites and stalagmites.
The lake water is brackish, a mixture of sea water and sweet water. The cave is about 500m from the sea and the water level is a meter higher than sea level. The brackish water rises from a 30m deep cave system on one side of the cave and flows to the other end of the cave. This was discovered by dye tracing experiments in 1959. Hydrogeologists Maurin and Zölt introduced around 140 kg of fluorescein into the sink holes at Katovothres. Fourteen days later, the water in Melissani and springs at Karavomilos appeared green. When the water re-appears it is less saline than when it entered the underground cave system
