The insanely pretty Greek island that's still not attracting as many tourists as Santorini
While Santorini is famed for its dramatic sunsets and vibrant nightlife, Kefalonia attracts visitors with its quiet charm, historical sites, and tranquil, uncrowded atmosphere. Melissani Cave, an underground lake with piercing turquoise waters, is a must-see. Visitors can take a boat trip to take in the striking cavern.
