There is a nice daytrip to be done from Bahar Dar to Blue Nile Falls. Getting there is more than half the fun. I have made a little Video with my Cell and posted it.
Gives a estimate how life on the road is in Ethiopia.
The Blue Nile experience is a couple of hours wandering around in the beautiful Ethiopian landscape. There is an old Bridge
A suspension bridge and of cause the Blue Nile falls. To be completely honest I do not think that the falls are worth going there for. They are using most of the water to generate electricity. And of cause your are not going there on your own. It seems like everybody from the nearby villages are trying to make a buck from old granny to very young children selling souvenirs or just begging. They can be quite desperate and persistent. The beautiful Ethiopian scenery though is second to none and is a nice break from Bahar Dar.
