Castlereagh Reservoir
Nestled in the highlands near Hatton, Castlereagh Reservoir offers a serene landscape of terraced tea plantations and calm waters, far from the beaten tourist trail.
Castlereagh Reservoir stretches across Sri Lanka's highlands near Hatton, at the heart of a tea plantation landscape. Created by a dam on the Maskeliya River, this artificial lake offers a striking setting: still waters ringed by verdant hills and terraced tea gardens. It is a place of serene nature, little frequented by standard tourist circuits, that appeals to hikers and lovers of high-altitude scenery.
What to see
The reservoir itself is the main spectacle: a vast expanse of water surrounded by tea plantations as far as the eye can see. Misty mornings are particularly photogenic here. The surrounding hills, some rising above 1,500 meters, frame the lake and allow for walks with sweeping views over the water and cultivations.

History and context
The Castlereagh Dam was built during the British colonial era to supply water to the region and support the tea industry. It is part of a network of reservoirs developed in the Ceylon highlands, alongside the nearby Massakela Reservoir. The Hatton region owes its economic development to the boom in tea plantations in the nineteenth century.
Highlights of your visit
The shores at sunrise
Early in the morning, mist descends over the water and hills disappear into clouds. This is the most spectacular time to observe the reservoir, before light disperses the blanket of fog.
Tea plantations along the shoreline
The tea gardens surrounding the lake are accessible on foot. You can observe tea pickers at work and understand the production cycle of Ceylon tea in its natural setting.
Walks along the heights
Paths running along the ridges offer sweeping views over the water. Walking is accessible without specialized equipment, though trails can be slippery after rain.
Photography tips
Morning light, between 6 a.m. and 8 a.m., is ideal: mist creates depth effects on the water and hills. Choose a high vantage point from the ridge paths to frame the lake with rows of tea bushes. During the rainy season, low clouds add dramatic atmosphere.
