South Omo Valley - here you can till find tribes that have not adopted modern life styles. On market days day mingle amongst each ther and more and more modern life. In the villages traditional life continues, although modern influences become more visible probably every year. Still: some of the moremote villages remain absolutely traditional, although the places where tourists are brought will make you feel quite double-hearted: it's a great way to see their lifes and photografe them, but yhose photographs (and the fact you're supposed to pay for every person in every pic you shoot) make it a slightly upsetting, yet unforgettable exoerience to visit - for instance - the Mursi tribe. Much less of a hassle is a visit to a Hammer/Benna bull-jumping-cremony. You pay 300 to 500 Birr pp, and will also be forced into hiring a guide (around 200 Birr) but once you're there you will be able to enjoy the ceremony from as close as you wish and can walk around pretty much anywhere. Amazing to witness!
