Visas heading north
 

Hello. Two Australians here currently in jinja. We have travelled from Cape Town and we have two months to get to London. No longer! We are thinking of riding to Egypt and then through Europe or flying to Istanbul and then spending more time in Europe. My question is do we have enough time to stuff around getting visas for Ethiopia Sudan and Egypt. Theses are prooving tough to get while heading north and I feel like it will eat too much time.but before I book air freight I'd like some thoughts, preferably by those who have actually done it south to north.

Anyone?
