Kefalonia’s Fascinating Geological Wonder
The Argostoli Sinkhole, also known as the Katavothres, is a remarkable natural phenomenon located near Argostoli, the capital of Kefalonia in Greece. This unique geological feature plays a central role in the island’s underground water system, where seawater mysteriously disappears into the ground and travels through subterranean channels before reappearing on the other side of the island.
Situated approximately 2.5 kilometers north of Argostoli, the sinkholes are an excellent example of karst topography, a landscape formed by the dissolution of soluble rocks like limestone. This process creates caves, underground rivers, and sinkholes, such as the Katavothres. Seawater enters the sinkholes and travels through an intricate network of underground channels, eventually emerging at Karavomilos and other locations.
Although the phenomenon has been known since ancient times, it wasn’t until the 1960s that scientists were able to confirm the water’s path. Austrian geologists conducted dye tests to track the flow of the seawater, proving that it passes through areas like the Melissani Cave before resurfacing on the opposite side of the island.
Today, the Argostoli sinkholes are a popular tourist attraction, drawing visitors interested in Kefalonia’s unique geological features. Visitors can observe the point where the seawater disappears underground, learning about the island’s fascinating hydrology and geology. With its scenic surroundings and proximity to other local attractions, the Katavothres offers a captivating glimpse into the natural wonders of Kefalonia.
