What documents are required for the 60-day visa exemption for tourists in Thailand?

To enter Thailand under the 60-day tourist visa exemption, you'll generally need just your passport. However, it is recommended to have proof of onward or return travel, such as a flight itinerary, and possibly accommodation arrangements, although these are not consistently required. Ensure that your nationality is on the visa exemption list, and be prepared for potential questions at the departure check-in.
