Dondra Head Light—the southernmost lighthouse in Sri Lanka, constructed of octagonal imperial granite blocks in 1889—features a focal plane 47 meters above mean sea level. Its international characteristic is Fl W 10s (one white flash every 10 seconds), with a nominal visual range of 28 nautical miles. Sri Lanka Ports Authority and Navy coastal radar stations track maritime traffic in the Traffic Separation Scheme (TSS) located roughly 5 to 10 miles south, broadcasting warnings to deep-draft ULCC crude carriers drifting too close to nearshore rocky shoals.
Local artisanal fishing boats anchor close to the shallow reef line with dim lights; yachts arriving from Galle must run forward radar to avoid collisions.
The granite tower grounds provide clear horizons to shoot long-exposure star trails arching over the Indian Ocean before lighthouse beam flare washes the frame.
The coastal upwelling directly off Dondra Point concentrates krill swarms that draw blue whales close to the coastline between December and March.
Climbing the 196 internal spiral stairs requires clearance from the Ports Authority office, accessible during daylight hours only.
The ocean swell pounding against the concrete wave-breaker blocks creates heavy mist; keep cameras sheltered from salt spray along the seawall.
