About this tour
When Lily from our BugBitten team ran this four-hour boat tour off Zakynthos, we spotted loggerhead turtles in their natural habitat, swam in the shallows around Marathonissi, and cruised past the dramatic rock formations at Mizithres and into Eros Cave. The Greek island's southern coast feels quiet and unhurried — mostly other small tour groups and families, with local captains steering confidently between limestone cliffs and sandy coves. It's a proper coastal experience without the nightclub-bar crowd.
Highlights
- Caretta-Caretta turtles swimming metres from the boat — not in tanks
- Multiple stops for swimming in warm, clear Ionian water
- Mizithres rock pillars rise dramatically; photos are genuinely stunning
- Eros Cave interior glows with reflected light off pale stone
- Relaxed pace, four hours feels unhurried and unhyped
- Local captains know where turtles typically feed and rest
- Mix of families and groups keeps vibe friendly, not rowdy
What to expect
You board a modest boat with maybe 20–30 others and head south along the coastline. The first stop is often Marathonissi, a small island where you can wade in and swim for 20–30 minutes; the water is genuinely clear and warm. The captain will point out turtles resting near the seabed or surfacing for air — this is the main event, and it delivers. Between swims, you cruise past Mizithres, two towering sea stacks that jut from the water like sentries, and the boat motors into Eros Cave, where the limestone walls narrow and the light hits the water in pale greens and blues.
The whole thing moves at a sensible pace. You're not rushed between spots, and the captain explains what you're seeing without talking endlessly. Lily noted the water can be chilly first thing in the morning, and the sun exposure is real — the boat offers little shade — so timing and sunscreen matter.

Good to know
If you want a genuine turtle encounter without pretence or tanks, this works. The swimming is refreshing, the scenery is proper Mediterranean, and the boat is stable enough for most swimmers and non-swimmers. Admission is covered, so no hidden fees jumping out at checkout. Kids and infants are welcome (prams fit), and there's no heavy fitness demand — you float and look, mostly.
Early starts are standard for boat tours, so early risers win. Sun exposure is intense; pack high-SPF sunscreen and a hat. The boat can feel crowded if you're hoping for a private-yacht vibe — expect 20–40 people. No undercover seating means weather sensitivity is real; in rough seas or rain, the magic fades fast. Swimmers should be comfortable in open water, even if shallow. The cave is beautiful but brief — five to ten minutes of actual cave time.
