Flores roads are weaving and potted so hiring a driver or booking a trip through an agent takes a great deal of stress and wasted time out of travelling around. We used Golo Hilltop ( http://golohilltop.com/main.html) who were excellent. However, you could decide to do Le Tour of Flores as did a crazy couple we met from Holland, or should that be the Netherlands; does anyone know, or for that matter care? Le Tour had 4 spare inner tubes, 2 spare tyres, 27 gears and lycra. 'But isn't Holland flat?' ' Ve train in Switzerland', hmm, obviously. Le Tour were hard core, if they could not find accomodation, they had their own tent in the 4 paniers each they loaded; 've carry essentials, ve do not need clothes' - naturalist Le Tour, now there's an idea.
