Air Burkina (www.air-burkina.com) has two flights per week between Ouagadougou and Bobo-Dioulasso (CFA55,000).
Cycling in Burkina Faso can be great, as long as you keep in mind that the roads are not always paved, and that city traffic can be chaotic.
It is not possible to travel within the country by boat.
Buses are the most reliable and comfortable way to get around the country. They almost always operate with guaranteed seating and fixed departure times; arrive early or book the day before to ensure you have a seat on your preferred service.
Car & Motorcycle
Travel agencies in Ouagadougou can organise 4WD rental (with a driver) for about CFA60,000 per day.
In rural areas, mopeds are ideal on unsealed roads and readily available for CFA5000 per day (not including fuel).
There are Sitarail trains between Ouaga and Bobo, but they can take up to 10 hours and are highly unreliable.
Taxis-brousses (bush taxis) are generally beaten-up old vehicles that cover routes to outlying communities that large buses don't serve. Most leave from the gares routières (bus stations); morning is the best time to find them. There are more-or-less fixed prices, starting from CFA1000, that local people share. You can bargain if you're hiring one alone.
