Lonely Planet has this to say about Ethiopia, in the eyes of a tourist:
Ethiopia has the ability to wow you day after day. This is truly a world apart; there are more than two millennia worth of ancient treasures scattered around Ethiopia, from the giant obelisks and hidden tombs of the legendary Queen of Sheba, to castles that would make Camelot jealous and the breath-taking rock-carved churches of Lalibela. Not to be outdone by human craftsmen, Mother Nature really let her creative juices flow in Ethiopia. East Africa’s Rift Valley has left some of its most memorable signatures here: volcanoes bubble and boil, lakes are the colour of English tea and deep canyons and steep peaks wrinkle the land…well, just about everywhere.
If you do visit Ethiopia, be sure to look up Dr Rick Hodes and his team. You will be inspired.
