The Melissani Cave Lake is a magnificent, underground lake with part of the ceiling open, letting bright blues illuminate the waters. Visitors explore this lake using small paddleboats, guided by local boatmen, while gazing at stalagmites, cave walls, and their reflections. It is also historically affiliated with the Greek nymph Melissanthi and the god Pan, further adding mythological charm to the already natural beauty.
The cave is open all summer days, but it is worth visiting around midday for the best light inside. Tickets are about €10 for adults, with discounts for children and a combination ticket with Drogarati Cave. This cave is a must-see for photographers, nature lovers, and anyone touring Kefalonia's highlights.
Because Melissani Cave is easily accessible from Sami and Argostoli by car or tour, it's ideal for a half-day adventure on the island.
