Unless you're a completest, and just have to see everything, the Melissani Caves can absolutely be missed. A boat tour through the cave is surprisingly expensive, and faily short (about 15 minutes) The cost is about 10$ The cave is not that expansive, and the dim lighting make quality pictures quite difficult with normal cameras. The cave has an opening in the top, allowing some sunlight to come in to expose the stone walls, the boat captain will row you in a circle around the cavernous area and down to a more secluded alcove and back. Overall there is nothing spectacular about this activity
I have read that a statue of the god Pan was found on a small island in the middle of the lake but have not seen the statue. It is on display in the museum in Argostoli. The Odysseus says that Ulysses hid the treasures of Alcinoos in Melissani caves (that had still their roof!)
Melissani caves are found 3 km north to Sami, a few hundred meters off the road to Aghia Efimia. It is the most striking geological phenomenon on Cefalonia: it was a subterranean lake, which vaults collapsed during the big earthquake. Before that, shepherd new that the area was dangerous as sheep sometimes disappeared in narrow faults into the vault and fell into the lake. Now that a part of the vault has collapsed, the sun illuminates the water that looks blue and makes interesting reflexions.
You will be proposed boat trips on the lake, rather expensive.
Geologically, Cefalonia is made of limestone. That means that it is a karstic land and thus, is “full of hollows”, I mean there are plenty of subterranean cavities!
Drogarati cave is one of them which is used for concerts. Melissani caves is another. Karavrothes, near Argostoli, is a third one. Actually, all three and several minor one lie on a fault that allows sea water to flow from Argostoli, on the west coast to Sami, on the east coast, 15 km away, as the bat flies.
Myrtos is the most famous beach on Kefalonia (Cephalonia) and has been voted one of Europe's most beautiful. The beach is a huge sweep of white limestone set a kilometer down from the road, it really is breathtaking
Myrtos Beach is reached via a steep, winding road that can get very busy during the summer, so arrive early or be prepared for a bit of a walk. The shore is mostly made up of coarse sand and spectacularly white pebbles that have to be seen to be believed.
Absolutely one of the best beaches I have seen
A word of warning, people do nude sunbathing at the end of the beach although i am told it is illegal?
The beach is set in a very dramatic horseshoe bay, with steep slopes all around. The water appears a deep shade of blue against the bright white pebbles. The back of the beach has been turned into a car park which somewhat detracts from the beach's beauty. You'll also be charged for the privilege of parking here.
It is a beautiful and attractive pebble beach with turquoise waters, surrounded by impressive verdant hills.
Thousands of visitors are attracted every summer by the natural beauty of the place.
