This article countains more info about Sudan.
A description of what I did, what I like the most and dislike the most.
I only got a 7 days Transit Visa, thanks to
the embassy in Ethiopia, to visit the biggest
country in Africa. So I haven’t take time to really visit the country and went almost in a straight to Wadi Halfa (Egyptian border). The contrast with Ethiopia was impressive, people are so nice! Among the more friendly I’ve met in Africa (Northern Mozambique is a close 2nd). THey all want to get out of Sudan so if you can print some info about getting a visa to your country you’ll be a star.
The kindness of the people
No tourist (almost) so you have the country for yourself
Down Sides :
The 26 hours ride from Kerma to Wadi Halfa (try to break the journey if possible
The assle to get the visa
