Tourism Handbook:

Don't listen to everything you hear about Iran in the media. In a country steeped in ancient tradition, there is a surprising essence of modern flair. Iran holds many surprises for visitors; like the climate which can fluctuate greatly, depending on the area and time of year, dispelling the long-held myth that Iran is nothing more than a vast, sweltering desert. While some surprises are nice when travelling, it's important to be as well prepared as possible. Despite its tarnished reputation, Iran can offer a unique travel experience, especially for those with a love of ancient history. The people who live there are warm and eager to share their country and heritage with visitors and those who travel there are certain to leave a little richer from the experience.
