Why we send people here

Twenty minutes in a tiny sappa skiff into a cove that glows cobalt — no reservations, sea decides. March to November, and worth rearranging a morning for.

Why it earns the hours
  • Our number 2 for Miyako, out of ten. It is the first thing we would spend the hours on.
  • Short enough to be certain of: 1 hr door to door, so even a tender day works.
Before you count on it
  • No single published ride covers this one. Budget for a taxi both ways, or fold it into a guided day.
The story

Why Blue Cave sappa boat is famous

A sea cave reached by sappa-bune, the small open boats local fishermen use, which are the only craft that fit through the entrance. Inside, light comes up through the water and turns the cave blue. It runs only when the sea allows, which is not most days in winter.
