Tourisim in Ethiopia - Ethiopian National Parks visit price?

How much do Ethiopian national parks charge visiting foreigners? What are the general basic rules while visiting the parks?

Don't know the exact amount, but in general the price will be at least double for foreigners than native Ethiopians. Sometimes the price is 10 times higher or more, in the case of Lalibela and when you visit the different monasteries in lake Tana.

Is there any established tourist attraction in Harar? Is Emperor Selassie's birthplace a tour site?
