There is so much more to see in Greece than just the mainland, such as all the islands just waiting for you to explore. One of the most interesting of these islands is Kefalonia, which is located in the Ionian Sea and known for both its natural beauty and its ancient ruins. Here are some of the best things to do while you visit the island:

Melissani Cave and Lake

The Melissani Cave and Lake is one of the most sought out places in all of Greece for tourists, and for a good reason. Located not far fromSami, this two-chambered cave is not your ordinary cave.  Those who venture inside the cave will find a lake and an entire forest with trees within.  There is also a balcony on top of the cave that provides stunning views of all that is below. A visit here is truly a once-in-a-lifetime experience.

Castle of Saint George

If you love old castles, a visit to the Castle of Saint George is a must. Located a little more than 4 miles from Argostoli, this 12th-century castle was originally built by both the Byzantines and the Venetians, with the latter building the wall around it. The castle is quite large and there are many ruins to explore.   While you are there you can also visit the ruins of the nearby Church of Saint Nicholas.

Cyclopean Walls of Ancient Krani

You may not know that Greece has its very own Great Wall. Located near the Temple of Demeter, the Cyclopean Walls have been compared tothe Great Wall of China. They are named after thelegendary one-eyed giant Cyclops that supposedly built them in 7th-century BC to protect the ancient town of Krani. The walls are about a mile long, and you will be amazed at how well constructed they are, with perfectly aligned stones.

Iakovatios Library and Museum

If you love books and libraries, a trip to Iakovatios Library and Museum will be well worth your time. Visitorswill find 20,000 books in this restored 14-room library, including 4,000 that were published prior to the 20th century. This includes The Complete Works of Hippocrateswhich was published at the tail end of the 16th century. The library also has fragments of Biblical parchments that date all the way back to the 10th century.

Katavothres

Located a little more than a mile from Argostoli is Katavothres, where you can witness a geological phenomenon that you can only witness on Kefalonia. There sea water runs over and through the cracks in the rocks before disappearing underground. While you are there, you can also visit the quaint village nearby as well as a pretty little beach, making it the perfect place to spend an afternoon.

Kefalonia is a wonderful island to visit while in Greece. There is no shortage of things to do and see there, and the beauty you will witness will remain with you for a lifetime.
