Just wanted to share my experience with you :)
My boyfriend and I went on a self drive holiday with Roadtrip Tanzania in September 2015. We hired a car and booked the Bush to Beach circuit of 17 days, from Arusha to Dar es Salaam. Having the freedom to stop anywhere you like is simply amazing.
The car, a Toyota Rav4, was in good condition and performed great during the road trip. They gave us GPS, a detailed roadmap and travel book, so it was easy to find our way around. I was surprised by the quality of the roads but Google Maps is so wrong about the driving times. Definitely add 1 or 2 hours on top of what Google Maps is indicating.
Thanks to Roandtrip Tanzania for loads of travel tips and excellent advice. Many many thanks to you Andrew, for your assistance during our trip ☺. I don’t think we could have done this adventure without you! Best, Dasja
