A heritage itinerary here spans an unusually wide sweep of time. Anuradhapura's stupas were among the tallest structures in the ancient world, rivalled only by the pyramids at Giza. Polonnaruwa's Gal Vihara Buddhas were carved from a single granite face in the twelfth century. Galle Fort is a working town inside Portuguese and Dutch walls, with Dutch Reformed churches, mosques, warehouses and merchant houses still standing and still occupied.
The colonial layer is easy to miss and worth seeking out. The Dutch canal network around Negombo, the British-built hill railway to Ella, the tea estate architecture around Nuwara Eliya and the Kandyan-era temples with their painted wooden ceilings all sit within reach of the standard route.
These itineraries pair the major sites with the smaller ones that rarely appear in a fortnight's package — Ritigala's forest monastery, Mihintale where Buddhism arrived on the island, the Yapahuwa rock citadel. A licensed guide travels with you throughout.
