Unawatuna’s horseshoe bay – curved between two headlands just south of Galle – gives it reef-protected swimming conditions that most Sri Lanka beaches cannot match, with sea turtles resting in the shallows with enough regularity to make sightings realistic rather than hopeful. The proximity to Galle Fort makes a natural pairing: a morning among the Dutch colonial ramparts followed by an afternoon in warm, sheltered water is one of the south coast’s most satisfying combinations. The bay’s physical beauty has retained its appeal through decades of traveller appreciation.
