Mannar sits at Sri Lanka's northwestern edge, closer to India than any other part of the island, and it feels like it — arid, windswept, and dotted with African baobab trees that look almost out of place against the dry-zone landscape. Once one of the ancient world's great pearl-fishing centers, today Mannar is a quiet, still-underrated corner of the country rewarding travelers willing to go off the beaten path.
A History Shaped by Pearls and Empires
Mannar's location made it a prized trading post for over two thousand years — the Gulf of Mannar was once ranked alongside the Persian Gulf as one of the world's two great sources of high-quality pearls, and the area was mentioned as a major pearl-fishing center as far back as the 2nd century in the ancient Greek text the Periplus of the Erythraean Sea. Overharvesting eventually collapsed the industry, but the region's strategic value kept it contested for centuries. The Portuguese built Mannar Fort in 1560; it surrendered to the Dutch in 1658 and was rebuilt in 1696, before finally passing to the British in 1795. Its ruins still stand today, overlooking the Gulf of Mannar.
The Baobab Trees
Mannar's most distinctive feature is its concentration of baobab trees — a species native to Africa and Madagascar, believed to have been brought to Sri Lanka by Arab traders centuries ago. Of roughly 40 baobabs found across the entire country, the vast majority grow in the Mannar region alone. The most famous, the Pallimunai Baobab, is estimated at over 700 years old and measures some 19.5 meters in circumference — the largest tree in Sri Lanka by girth. Locals call it "Ali Gaha," or the Elephant Tree, for the way its rough, grey bark resembles elephant skin.
Wild Horses of Mannar
Alongside Delft Island, Mannar is one of only two places in Sri Lanka where feral horses roam freely — descendants, according to local tradition, of animals brought by Arab merchants long ago. The wetlands just west of Mannar city are the best place to spot them, alongside wild donkeys and a striking range of birdlife.
Adam's Bridge and Talaimannar
At the island's western tip lies Talaimannar, a small fishing village and reputedly the windiest spot in Sri Lanka — making it a growing destination for kite-surfing. From here, a chain of limestone shoals known as Adam's Bridge (or Rama's Bridge) stretches toward India's Rameswaram Island, geological evidence of what may once have been a land connection between the two countries. In Hindu tradition, the same shoals are tied to the Ramayana, said to have been built by Lord Hanuman's army so Rama could cross to rescue Sita.
Birdwatching and Wetlands
The Vankalai Sanctuary, a protected wetland near Mannar, draws large flocks of migratory birds each season, including flamingos, pelicans, and herons — one of the best birdwatching sites in the north of the island. The rare fishing cat has also been recorded in the area's wetlands.
Religious and Cultural Sites
- Our Lady of Madhu Church — one of Sri Lanka's most revered Catholic shrines, with a history spanning over 400 years, set within a peaceful forest
- Thiruketheeswaram Temple — an ancient Hindu temple dedicated to Shiva, one of the island's five sacred Ishwarams
- Doric Bungalow, Arippu — the former residence of Frederick North, the first British Governor of Ceylon, now a scenic ruin
Beaches and Coastline
Keeri Beach, a few kilometers outside Mannar town, offers a quiet stretch of sand backed by palmyra palm groves — home to monkey troops, so it's worth keeping food secured. The coastline throughout Mannar tends toward wide, undeveloped, windswept beauty rather than resort-style tourism, part of its appeal for travelers seeking something quieter.
Getting to Mannar
Mannar Island is connected to the mainland by a roughly 3km causeway carrying the A14 highway, and sits about 325km from Colombo in Sri Lanka's dry northwest. Given the spread-out nature of its attractions — the fort, the baobab tree, Talaimannar, and the wetland sanctuaries all sit some distance apart — a self-drive rental is the most practical way to cover the island in a single trip.

Mannar rewards travelers looking for something genuinely different from the rest of Sri Lanka — ancient pearl trade history, colonial ruins, wild horses, and trees that look like they were transplanted from another continent entirely. It remains one of the country's quieter, less-visited corners, which is exactly what makes it worth the detour.
