You step out of an air-conditioned van onto granite ramparts that face the Arabian Sea; salt wind pushes at your shirt and the lighthouse watches like an old harbor-guard. The day unfolds along Sri Lanka’s southwest edge — a measured loop from Colombo through coastal villages to the Dutch-built streets of Galle, mangrove channels of the Madu River, the artisanal mask shops of Ambalangoda and a Kosgoda turtle hatchery.
