I want to book a guided tour, but I don't see any availabilities. What is the problem?

The guided tours through the Palais des Nations are very popular and often sell out weeks in advance. For groups, we recommend booking at least three months before your visit. 

For individual visitors, new availabilities open once a month: on the 20th of each month, we release the slots for the following month.

Tickets for individuals sell out quickly, so we encourage you to check our booking platform on that date.
