Try out the walking directions today. As a reminder, walking directions are currently in beta, and we recommend that you use caution, as the routes may be missing sidewalks or pedestrian crossings. Walking directions are editable, so if anything is amiss, you can correct it with our community mapping tool Google Map Maker. Google Map Maker is a tool that allows you to add and update geographic information for millions of users to see in Google Maps and Google Earth. We are always grateful to our active African online cartographers who have helped make our African maps what they are today.
