Many travellers come to Sri Lanka for its temples, and leave having seen a lot of them without quite understanding what they were looking at. That is a shame, because Sri Lanka offers something rarer than beautiful ruins: one of the oldest continuous Buddhist cultures in the world, still practised every day by the people you meet.
Theravada Buddhism has been central to life on the island since, according to tradition, the monk Mahinda brought it here in the third century BCE. Around 70 per cent of Sri Lankans are Buddhist, and the constitution gives Buddhism the foremost place. You will see it in white-clad families walking to the temple on full moon days, in the lanterns of Vesak, in the Bodhi trees on every village junction, and in the way people behave around a Buddha image.
That living quality is exactly why it rewards some preparation. A visitor who understands what a Poya day is, why the Bodhi tree matters, how to walk around a stupa and what not to do in front of a Buddha statue will have a completely different experience from one who treats temples as backdrops. And a small number of visitors each year discover, often unpleasantly, that Sri Lankans take respect for Buddhist images very seriously indeed.
This guide is written for travellers of any faith or none. It covers how to behave at temples, what the law and the courts have actually said about Buddha images and tattoos, the full moon calendar with the gazetted 2027 dates, the major festivals and pilgrimage sites, how to take part in offerings and meditation without overstepping, and how to put it all into an itinerary.
On dates: Poya days follow the lunar calendar, and Sri Lanka's public holidays are fixed by government gazette. The 2027 list was published in Gazette Extraordinary No. 2493/05 dated 16 June 2026. We have used dates reported from that gazette and say clearly where we could only confirm them second-hand.
