Kefalonia’s rugged western coastline, its underwater caves and the more remote Ionian islands to its south and west are ideal territory for an explorer yacht. The island’s western cliffs, rising 300 metres from the sea near Myrtos, are flanked by sea caves accessible only by tender or from the water, and the diving off the south coast produces encounters with ancient amphora fields from trading routes that passed here in antiquity. Three explorer yachts charter in Ionian waters, and Kefalonia is among the most compelling starting points for an expedition-style itinerary. Explorer yachts in this area range from 35 to 65 metres, combining long-range fuel capacity, a well-equipped tender garage and a full diving and water sports inventory with the accommodation standards of a conventional superyacht. The independent anchoring capability means the itinerary is not constrained by marina availability, a significant advantage in peak season when Fiscardo’s small harbour fills days in advance. Explorer yacht charter rates around Kefalonia start from 75,000 euros per week for a 35-metre vessel and rise above 350,000 euros for the largest expedition yachts. The provisioning allowance of around 30 percent covers dive gas, water toy use, provisions and fuel. A Kefalonia explorer itinerary combines the sea caves off the north coast accessible only by tender, the amphora dive sites off the south of Ithaca, the remote Strophades islands a full day south-west of Zakynthos, and an underwater volcanic landscape further afield for a genuinely expedition-grade Greek charter.
