If you’re looking for a tour operator for Tolanaro (Fort Dauphin), Madagascar, I just booked a tour with DODI’S LEMUR TOURS. This tour operator has very good reviews on Trip Advisor but I've never used them before, so I can't give a personal recommendation. He has been super-fast to respond to my emails and provided me with a nice description of the tour and pictures of the vehicle. There is no deposit required (pay in cash on day of tour). His website and email are: http://www.dodislemurtours.com and dodiasjustin@yahoo.fr
