I want to recommend a guide, Lalo Desse, who worked for me in the Lower Omo River Valley in S. Ethiopia in 2006. He was a magician, allowing me to travel in very hard circumstances with a measure of comfort and very inexpensively. He has just started a small, shoestring touring company that can be googled at www.lalo-tours.com They specialize in “alternative” travel, but can take anyone anywhere for any purpose in Ethiopia for a very reasonable price. His telephone contact is 251 913 363 077 (int’l) or 0913 363 077 (in Ethiopia). I would highly recommend Lalo’s company for anyone wanting to travel anywhere in Ethiopia.
