Melissani Cave is a place you absolutely don’t want to miss on your trip to Greece. Also known as Melissani Lake, it’s on the island of Kefalonia. And after seeing a picture of it on Pinterest, I knew I just had to go.

Melissani Cave is closest to Sami town and Agia Efimia, where I stayed.

I’ve never seen water so many shades of blue in a cave. And, the light that filters in the opening of the cave creates water so clear that it sparkles.

Board a boat and enjoy seeing the two chambers of this underground lake.

Part of the lake has the sun streaming in, and the other part is a dark cave with 20,000 year old stalagmites and stalactites.

Magical light filters in at the edges of the cave, creating an experience that is just breathtaking.

With such stunning beauty, it’s easy to see why this magical cave was considered to be home to the nymphs in Greek mythology.

An earthquake caused the ceiling of the open cave to collapse into the lake, leaving it even more beautiful than it was before.

The Melissani Cave entrance fee is 7 euros which includes the boat ride into both caves. Make sure to bring a tip for the boatmen who are friendly and full of information. And, they will take your picture for you, so you don’t have to take a selfie. The boat ride lasts about twenty minutes.

It’s truly the most colorful cave I’ve ever visited. The transition from the light to the dark cave is quite the ethereal experience.

To capture the full magnificence of the cave, make sure to visit when the sun is shining overhead. I also recommend visiting as early as possible, as many tour buses arrive later in the day. If you visit in off-season, chances are you will have the place to yourself. Go, and be amazed!
