Can I enter Sri Lanka multiple times on a tourist visa?

A standard 30-day tourist ETA gives you a double-entry option. With it, you can exit Sri Lanka and then come back once during your first 30-day period.

This can help if you plan a short stop in another place, such as the Maldives or India. Just remember this: your return visit has to happen within 30 days from when you first arrived. If you want more than two entries, you will need a new visa type or a fresh ETA.
