A day on the water South coast, by boat from Pythagoreio Best June–September

Kasonisi is a small islet off the south coast, with clear turquoise water and rocky coves that are ideal for swimming. It is a boat destination rather than a place you drive to, so the practical plan is a day trip from Pythagoreio's harbour. Go for the swim stops and the sea; don't expect facilities, and bring your own shade.

What to see and do

  • Swim stops in clear water — the reason to come: sheltered, turquoise coves and easy snorkelling.
  • A day trip by boat — boats leave from Pythagoreio harbour, so the day starts and ends in town.
  • Quieter coves — a private charter can reach spots the group boats skip, on your own schedule.
  • Sea views back to the coast — the south-east shoreline looks very different from the water.
