Togo's international airport, Tokoin Airport, is 6km (4mi) north-east of central Lomé, and there are taxis and buses available there to take you into town. Don't count on flying between destinations within Togo, as, aside from a few charter planes, nearly everyone gets around on terra firma. Air Togo flies between Lomé and Niamtougou on Friday and Sunday.
Though cars are available for rent in Togo, the going rates are astronomical; you're usually better off hiring a cab for your trip. Most major roads are sealed and in decent shape, but outside of these highways you'll need a 4WD. The roadway between Atakpamé and Kara on the main north-south axis is in particularly poor condition. Intercity travel is best restricted to daylight hours, as highway crimes are not uncommon. Driving in Togo is on the right.
Togo has an extensive network of minibuses, and most of them are in fairly reasonable condition. Fares, on the other hand, are very reasonable (about US$1 per hour), though there's a surcharge for luggage. Be prepared to do some hard bargaining to keep it down; US$.50 per piece is about right.
Travelling by bicycle is an excellent way to explore Togo and greatly reduces your time spent at police checkpoints. Although most secondary roads are unpaved, they're generally in passable condition except during the rainy season. Bikes are available for rent in larger towns and tourist areas.
