Hop on a boat from the nearby shores of Laganas or Keri and cruise across the turquoise waters to Turtle Island, a protected paradise in the National Marine Park. This uninhabited islet is a crucial nesting ground for loggerhead sea turtles, and if you're lucky, you might spot one gliding through the crystal-clear sea. You'll have time to swim and snorkel off the island's beautiful beaches, but remember that access is limited to the shoreline to protect the precious turtle nests, making it a truly special and eco-conscious experience.
