Bus service to the north coast villages of Fagamalo, Fagasa, Masefau, Aoa, and Onenoa is infrequent, so to reach them easily you'll need to rent a car. Several car rental companies have counters at the airport. If no one is present, use the nearby public telephones to call around, checking current prices and requesting a car delivery to the airport.
The most professional car rental company on Tutuila is Avis. All of their cars are kept at the airport but you must make an appointment for their representative to meet you there. Friendly Car Rental is on the way to the Pago Airport Inn at Tafuna.
All rates include unlimited mileage and all vehicles must have public liability insurance, although collision insurance is often not available. Most of the agencies only rent to persons over the age of 25 and your home driver's license is honored here for 30 days. Lock your car and don't leave valuables in sight. One of the biggest problems with driving on Tutuila is the lack of places to pull over and get out. Most villages have open fales facing the beach, so you'll often feel like an intruder.
Driving is on the right and the speed limit is 48 kph (30 mph) unless otherwise posted. You must stop if you see a yellow school bus loading or unloading, unless the driver signals you to proceed. Transporting open alcoholic beverage containers is illegal. Motorcyclists must wear helmets.
Rory West of North Shore Tours (tel. 258-3527, 644-1317, or 644-1220) offers a wide range of hiking, mountain climbing, bird-watching, snorkeling, and boat trips at very reasonable prices. If you want to hike along Tutuila's rugged north coast, climb Rainmaker Mountain, or get dropped off at an inaccessible bay for a few days of real Robinson Crusoe living, Rory is the guy to call. He also has a good knowledge of Samoan plants. His base is at Vatia, so many of the trips leave from there.
The travel agencies above the post office in Fagatogo or your hotel desk can arrange sightseeing tours of either the east or west sides of Tutuila.
