Events and Festivals
- Vesak Poya (full moon, usually mid-May) - paper lanterns, pandals (illuminated storyboards), and free food stalls (dansal) across the city
What to Do This Season
- Walk the illuminated streets around the sacred city after dark during Vesak week
- Sri Maha Bodhi draws its largest lay crowds of the year - a different experience than a quiet weekday visit
What to Watch Out For
- Inter-monsoon rain can arrive suddenly in heavy bursts
- Alcohol sales are restricted on Poya days nationwide
What to Wear
Light, modest clothing for temple crowds, sandals that handle both heat and sudden rain.
Is It Worth Visiting Now?
Yes, with planning - Vesak Poya fills the sacred city with lanterns and pilgrims, worth seeing once but expect crowds at dusk.
