Can I visit Sri Lanka on a transit visa?

Yes. People travelling through Sri Lanka on their way to another destination can request a free transit visa. It is valid for up to 48 hours.

This short permission suits travellers who have long wait times. With it, you can go out of the airport and spend a day in Colombo. Still, you must apply for the transit ETA online before you arrive. Have your connecting flight details on hand for the officials.
