Gal Oya National Park, in Sri Lanka’s lesser-visited eastern region, is one of the island’s most scenic and ecologically rich reserves.
Established in 1954, the park protects the catchment of the Senanayake Samudraya reservoir — the largest in Sri Lanka. It is the only national park in the country where boat safaris are possible, offering the extraordinary chance to see elephants swimming between islands. The surrounding landscape is strikingly diverse, with forested hills, savannahs, turtleback rock formations and low grasslands, providing a serene, varied environment that remains blissfully undeveloped by mass tourism.
Wildlife is abundant here, with 32 recorded mammal species including leopards, elephants, sloth bears, grey langurs and endemic toque macaques. Over 150 bird species are found in the park, from painted storks and ospreys to the rare painted partridge and endemic red-faced malkoha and spurfowl. Crocodiles, lizards and natricine snakes can also be seen in and around the park’s lakes. Gal Oya’s layered terrain includes historical sites like the Digha Vapi Dagoba and Henebedde cave. Though tourism infrastructure is minimal, day safaris are possible from Treetops Jungle Lodge or by staying at Gal Oya Lodge — both excellent bases for exploring this remote and rewarding corner of Sri Lanka.
