How to book train tickets in Laos?

Booking train tickets in advance is straightforward using the official train app. You can pay with your credit card and even get a refund if your plans change. I've used it a few times and it's worked out well. Just be aware that the trains can be delayed, especially during the rainy season.

If you're planning a long trip, it's better to buy tickets individually rather than relying on a single purchase. This way, you can ensure you have a ticket for each leg of your journey.
