At the heart of Sri Lanka lies the Cultural Triangle, where 2,000-year-old kingdoms left behind extraordinary monuments. The rock fortress of Sigiriya, with its frescoes and lion gate, is the unmissable highlight.
Nearby, the cave temples of Dambulla glitter with Buddha images, while the ruined cities of Anuradhapura and Polonnaruwa sprawl with stupas, palaces and ancient reservoirs.
Climb Sigiriya at dawn to beat the heat and the crowds, and pair it with neighbouring Pidurangala for the classic view.
