Driving through the Congo is an experience unto itself. Even if you've been to Africa before, it can at times be a bit surprising. As with many places in Africa, you can be overwhelmed with the friendliness and interest the locals will have towards you. Of course, this is the Congo so the security situation is generally pretty fluid and you'd be wise to mind your surroundings. Not to worry though, Virunga will provide you with a ranger to accompany you throughout the park for added security.
As I went from camp to camp in Virunga, I found the drives absolutely fascinating. Plenty of people everywhere. School children going or coming back from school, and always the assortment of people seeming sitting around and relaxing. The Congo is one of the absolute poorest countries in the world despite being loaded with oil, gold and diamonds. It's economy is clearly not exactly functioning at full blast.
