In the quiet heart of Sri Lanka’s Eastern Province, where mist rises from ancient reservoirs and the cries of eagles echo across granite hills, lies Gal Oya—a name that flows through the island’s history like the river it honors. This is not just a national park. It is a living archive of indigenous wisdom, a refuge for rare wildlife, and a sanctuary of silence where elephants swim between islands and the forest breathes with stories untold.
The name Gal Oya translates from Sinhala as “River of Rocks”—“Gal” meaning rock and “Oya” meaning river. The Gal Oya River, which originates in the Uva highlands, carves its way through the landscape before feeding the Senanayake Samudraya, Sri Lanka’s largest reservoir. This river has long been a lifeline for both people and wildlife, and its name reflects the rugged, granite-strewn terrain that defines the region.
Historically, the Gal Oya Valley was home to Sri Lanka’s indigenous Vedda people, who lived in harmony with the forest for millennia. The area also sheltered Sinhalese kings, including King Tissa in the 2nd century BCE, who sought refuge in nearby Digavapi, a site believed to have been visited by the Buddha himself2.
The park was officially declared in 1972, not only to protect the displaced wildlife from the reservoir’s construction but also to preserve one of the island’s most vital elephant corridors. Today, Udawalawe stands as a symbol of coexistence between conservation and development, a rare success story in the global narrative of protected areas.
In the 1950s, the Gal Oya Development Project—Sri Lanka’s first major post-independence infrastructure initiative—transformed the valley with the construction of the Senanayake Samudraya Dam, reshaping the landscape and giving rise to Gal Oya National Park, established in 19542.
Gal Oya is one of Sri Lanka’s most ecologically diverse and least disturbed national parks, offering a rare blend of evergreen forests, savannah grasslands, and aquatic ecosystems. It is the only park in the country where you can witness elephants swimming between islands—a spectacle that is both surreal and deeply moving.
