Sri Lanka fits ancient kingdoms, cool tea country, wildlife parks and long beaches into an island smaller than Ireland. In two weeks you can climb Sigiriya, watch the evening ceremony at Kandy’s Temple of the Tooth, take the train through the hills, look for leopards and end on the south coast.
The trip is driven, not flown, so a good driver-guide makes the holiday. Distances look short but roads are slow, so we keep most drives under four hours and build in two nights in most places.
The honest caveat is the monsoon. Two monsoons hit different coasts at different times, so there is always a good beach, but not always the one you pictured. Check the latest FCDO advice too, which currently covers flooding and fuel limits.
