Jaffna.

Jaffna deserves several unhurried days if you make the long journey north. Visit religious places respectfully and follow local guidance; the city's culture should be experienced on its own terms.

Sri Lanka Tourism's northern guide presents Jaffna through its religious sites, fort and wider peninsula. This is a place with a cultural identity of its own, not merely a long extension of a southern circuit. The journey north is significant; reward it with enough nights to explore beyond one landmark.
