Airports & Airlines
Departure tax is included in the cost of your air ticket.
Border crossings with Côte d'Ivoire are just beyond Sanniquellie towards Danané, and east of Harper, towards Tabou.
From Harper, you must cross the Cavally River by ferry or canoe to reach the Ivoirian border. Plan on two days if you want to reach Abidjan via San Pedro using public transport along this route.
Alternatively, daily bush taxis go from Monrovia to Ganta and Sanniquellie, from where you can continue in stages to Danané and Man (12 to 16 hours).
For Guinea, the main crossing is just north of Ganta. From just north of Ganta's Public Market you can take a moto-taxi (motorcycle taxi) the 2km to the border and walk across. Once in Guinea, there are frequent taxis to N'zérékoré. From Sanniquellie's bush-taxi rank, known as the 'meat packing', there are irregular bush taxis via Yekepa to the Guinean town of Lola (US$6.50). A place in a shared taxi is the same price. A moto-taxi (if you can find one!) from Yekepa to the border should cost US$1, after which there are Guinean vehicles to Lola. There is also a border crossing at Voinjama to Macenta via a bad road from Gbarnga (often impassable in the wet season).
Using a 4WD, you can reach Freetown in about 10 to 12 hours from Monrovia. The main Sierra Leone crossing is at Bo (Waterside). There are frequent daily bush taxis between Monrovia and the Bo (Waterside) border (three hours), from where it's easy to find onward transport to Kenema (six to eight hours in the dry season and 10 to 12 hours in the wet), and then on to Freetown.
There is currently no passenger ferry service serving Liberia.
