Yaoundé is the capital of Cameroon, while the larger Douala is the economic center. Yaoundé has this friendly ambiance and it never feels too crazy, except around the super crowded central market. There aren't an awful lot of sights, but there are a handful of interesting art deco 1970s government buildings along with some museums like the Blackitude and National. The Notre Dame Cathedral, built in 1955, has some pretty Afrocentric mosaics. You can climb the "bell" tower for magnificent panoramic views over the city and the surrounding hills.
