Kalutara Bodhiya
A must-visit spiritual landmark, the Kalutara Bodhiya is one of Sri Lanka’s most revered temples. The striking white stupa greets visitors as they enter town, overlooking the waters of the Kalu Ganga. As one of the only hollow stupas in the world, this serene temple offers a glimpse into the island’s deep-rooted Buddhist traditions.
Richmond Castle
This early 20th-century mansion is a testament to Sri Lanka’s colonial past. Richmond Castle features stunning architectural details, historic gardens, and beautifully preserved interiors that showcase the lifestyle of the era’s aristocracy.

Visit the hatcheries at the sanctuary to understand rescue initiatives and support ongoing protection programmes. If you want to stick around for early morning hatchings, consider staying at a nearby luxury hotel in Sri Lanka, as some places, like Anantara Kalutara Resort, offer excursions to the sanctuary.
