Why Kefalonia is a Snorkeller's Island
Kefalonia's waters offer an exceptionally clear window into the underwater world. The Ionian Sea's combination of low turbidity, clean water and complex rocky coastline creates ideal conditions for snorkelling: excellent visibility year-round, diverse seabed habitats of rock, sand and sea-grass, and a resident marine community that includes several species you are unlikely to encounter elsewhere in the Mediterranean.
No special training is required — a mask, snorkel and fins are enough. Children can begin snorkelling from around age six with parental supervision, and equipment is available to rent at most beach resorts.
Best Snorkelling Spots
Foki Beach (near Fiskardo): One of the finest snorkelling beaches on the island. The rocky seabed is home to octopus, moray eels, sea urchins and diverse wrasse species. Very clear water and a shallow entry make it ideal for all levels.
Dafnoudi Beach: Similar rocky substrate to Foki, with the addition of sea-grass meadows that attract sea bream and mullet. The smooth pebble beach makes entry and exit straightforward.
Antisamos Beach: The deep azure water and white-pebble seabed attract larger fish — dentex and sea bream are common. Snorkelling is best along the rocky edges of the bay rather than in the centre.
Myrtos Beach: The turquoise shallows at the southern end of Myrtos are home to numerous fish species and the occasional loggerhead turtle coming up for air. Enter carefully from the steep pebble shore.
Xi Beach (Paliki peninsula): The distinctive red-tinged sand creates an unusual marine environment. Look for flatfish, common sole and mantis shrimp along the sandy-rocky edges.
Skala Beach: The long sandy beach at Skala overlooks a feeding ground for loggerhead sea turtles (Caretta caretta), which come to the surface regularly during nesting season (May–September). Maintain at least 5 metres distance from any turtle you encounter.
Marine Life to Expect
- Fish: Sea bream, red mullet, wrasse (multiple species), parrotfish, damselfish, scorpionfish, moray eels, grouper
- Invertebrates: Octopus, sea urchins, sea cucumbers, starfish, hermit crabs
- Reptiles: Loggerhead sea turtles (Caretta caretta) — especially near Skala, Katelios and Mounda Beach
Equipment and Rental
Basic snorkelling sets (mask, snorkel, fins) are available to rent at most resort beaches for €5–10 per day. If you plan to snorkel regularly, bringing your own gear from home is worthwhile — even a budget set will be more comfortable and better-fitting than rental equipment.
Practical Tips
- Best time: May–October; visibility is typically best in May–June before summer algae
- Water temperature: Comfortable from late May (21°C) through October (22°C)
- Sun protection: The Mediterranean sun reflects intensely off the water — wear a rash guard and apply waterproof sunscreen
- Sea turtles: Do not touch, chase or attempt to feed loggerhead turtles; keep 5 metres distance at all times
