By bus
A few wealthy Gabonese entrepreneurs have invested in new buses for bus lines to service the larger interior cities. Mostly these buses serve the cities with paved roads leading to and from them. Since Air Gabon closed down, these bus lines have greatly increased their routes.
By car
There are lots of paved roads in Gabon, if you are staying in one of the major citys a car should suffice. If you plan on venturing onto some of the unpaved roads outside the major cities a 4x4 is recommended. There are less than 800km of tarred roads in Gabon - some of them in a bad condition. During the rainy season it is difficult to travel outside the major city areas even in a 4x4 vehicle.
By ship
Boat travel is available all along the coast of Gabon and dozens of miles up the Ogooue river to Lambarene. Boats leave daily to/from Libreville and Port Gentil. River trips from the mouth of the big river at Port Gentil to Lambarene Albert Schweitzer Hospital are available every few days. Hotel Olako arranges weekly boat transfers between Port Gentil and Omboué close to Loango National Park, transfers take between 3 and 4,5 hours depending on the type of boat and engine.
By train
The Trans-Gabon railroad goes from Owendo to Franceville. The trip takes 12-18 hours, there is a train every day of the week.November 2006: There are only 3 trains per week to Franceville: Tuesdays leaving Owendo at 9 a.m. - arriving in Franceville at 5 p.m. according to timetable, which is not completely reliable timewise. On Thursdays and Saturdays train travels through the night.
