As an engaging excursion option for those in search of island hopping adventures in the northeast, head over to the Batticaloa Lagoon in Sri Lanka. Home to Bone Island, Puliayantheevu Island and Buffalo Island, the scenic bridges that allow visitors to cross the lagoon and the Lady Manning Bridge are equally intriguing attractions. Head to the nearby Kallady Lagoon during the months from April to September to hear the famous ‘singing fish’ during your tour of the area.
