Garissa is small enough to get around on foot, but taxis can easily be hired. Beyond Garissa itself the roads are unsurfaced and frequently become impassable even by 4-wheel drive vehicles during the rains.
Transport from Garissa is good if heading for Nairobi. However, when trying to reach the coastal towns, such as Malindi or Mombasa, be aware that transport is very limited, with buses only leaving at around 5am. The Garissa - Mombasa road currently has an unsurfaced gap of around 60km, on which travel is fairly difficult without a 4-wheel drive vehicle. Give at least a day to travel this route.
