By plane
By far the best way to travel, but helicopter flights are restricted to UN personnel. Poor weather in the rainy season often forces helicopters to return especially from Voinjama.
By taxi
The best way to get around Monrovia. Most Monrovia taxis on the streets will pick up several passengers en route, and are therefore often jam-packed. Ask people you trust if they know of a reliable taxi driver to contact, as getting robbed in a taxi is a possibility. If you are unable to find one, consider hiring a taxi to your destination for your own use exclusively.
Long distance shared taxis leave from "Douala Station" in a northern suburb of Monrovia for destinations around the country. They are typically older yellow Nissan station wagons that leave when 10 passengers have purchased tickets. Fares for shared taxis are reasonable. For example, the three hour journey from Monrovia to Robertsport costs L$350 US$5 as of February 2010.
Alternatively, a "charter" taxi can be arranged for individual travel at a much higher price.
By train
There is no real train service. One track, which previously belonged to a mine, has been opened for tourists (http://www.internationals...). It travels to the Bong mines, a massive, defunct German run ore-mining and processing plant.
By car
The roads linking Roberts Airport to Monrovia and from Monrovia to the Sierra Leone border at Bo Waterside are paved and in excellent condition as of February 2010. Road conditions in some other areas are poor, so a 4x4 may be necessary for travel. During the rainy season, travel times are increased dramatically. Traffic through Monrovia can be slow, due to numerous traffic bottlenecks and damaged sections of road. Gas is sold in US gallons, not litres. Most distances and speed limits are posted in miles per hour.
