Sprawling over numerous hills and valleys, with roads that wind crazily around and across the contours, Kigali can be a confusing city to navigate. Just when you think you know where you are going, your destination appears on the horizon in another direction! However, it’s a fairly compact city and assuming that you aren’t put off by the idea of steep slopes, over-friendly children and changeable weather, walking is a fantastic way to get about. If you have just arrived, don’t forget that Kigali lies at an altitude of around 1,600m, so take it easy on the hills!
