Caving Tours in Kefalonia: Explore the Island’s Hidden Depths

Kefalonia isn’t just about beaches and sunsets. Beneath the surface lies a world of caves—cool, quiet, and full of wonder. The island’s caves are among the most impressive in Greece, and you don’t need to be a seasoned explorer to experience them.

Here’s where to go:

1. Melissani Cave

A crystal-clear lake inside a collapsed cave roof, where sunlight turns the water neon blue.

• Hop on a small boat.
• The guide rows you through the open-roof chamber.
• Then into a darker part that feels almost sacred.

It’s short but unforgettable.

2. Drogarati Cave

Just a short drive from Melissani, Drogarati is raw and powerful.

• 150 million years old.
• Massive stalactites and stalagmites everywhere.
• The main chamber has such good acoustics they’ve held concerts in it.

It’s cool down there—literally.

3. Aggalaki Cave

Located near Poulata, Aggalaki is the largest and most accessible cave in a cluster of interconnected caves.

• Features a small lake with striking blue waters.
• Sunlight filters through a natural opening, creating a mesmerizing glow.
• Surrounded by olive groves, offering a peaceful setting.
• Part of a larger cave system with unique geological formations.

4. Zervati Cave

Also known as the “Blue Cave,” Zervati is located in the southern part of Karavomilos village, about 250 meters from the sea.

• Features two small lakes with crystalline brackish waters.
• Home to rare aquatic plants, fish, and eels.
• The cave’s entrance was formed by the collapse of the roof of a pre-existing hall, creating a 10-meter-high debris cone that divides the cave.
• The ceiling and walls are adorned with intricate stalactites, and the light filtering through the roof casts magical hues on the water’s surface.

5. Abyss Cave of Agia Eleousa

Located about 2.5 km north of Karavomylos, this vertical cave has a depth of 75 meters and features a brackish water lake at its base. The cave is surrounded by dense vegetation, making its entrance nearly invisible. Due to its impressive depth and surrounding flora, it stands out as a notable natural feature in the area.

Know Before You Go

• Wear good shoes. Surfaces can be slippery.
• Bring a light jacket. Even in summer, caves stay cool.
• Go with a guide. Most tours include pickup, info, and some history.
• Combine Melissani & Drogarati. They’re close to each other—easy half-day trip.

Caving in Kefalonia isn’t about extreme adventure. It’s about discovering what’s hidden just out of sight. Natural cathedrals. Underground lakes. Spaces carved by time.
