We went to Akagera Park in April this year. You definitely need a 4×4 for the drive through the park at this time of year (the rainy season). It is not always easy to find and pre arange a driver. We drove with Kassim whom we met in Kigali. He has his own 4×4 and knows every area and National Park in Rwanda inside out and is very experienced and drove us safe even through areas where other cars got stuck. He knows all the wildlife and speaks English and French, which was very good. It might be helpful for other travellers to get his phonenumber +250 788 504 756 as we found it difficult to find someone.
