Tips for Visiting National Museum of Colombo #

  • Start your visit in the morning on a weekday to avoid weekend crowds and public-holiday surges at Colombo's main museum.
  • Plan your route so you leave time to stroll across to or from Viharamahadevi Park - the museum faces the park and combining the two gives a quieter interlude between galleries.
  • Begin with the major historical galleries and regalia rooms, which are often overlooked by visitors who rush through to reach the ethnographic and temporary exhibition spaces.
