Unexpectedly Difficult Countries to Visit in 2025

11. Iran: The Forced Tour for Certain Nationalities

For citizens of the U.S., UK, and Canada, independent tourism in Iran is a travel myth. These nationalities are required to travel on a fully guided tour with a pre-approved, fixed itinerary and a designated tour guide at all times. This not only makes the trip more expensive but also limits spontaneity and genuine interaction. While the culture and history are fascinating, the forced tour model and strict supervision make this an incredibly challenging and controlled experience.
