Quick answer
The Blue Caves near Cape Skinari in the north glow bright blue in the morning. Small boats leave from Agios Nikolaos and often combine with Navagio. In the south, Keri caves and Marathonisi ('Turtle Island') are reached from Keri and Laganas. Sea turtles nest in Laganas Bay, which has protected-zone rules.
What to know
- Morning is best for the blue colour.
- Small boats can enter caves; large ones cannot.
- Respect turtle rules: no boats near nesting beaches at night.
- Rough seas cancel trips.
