It is also possible to arrive by sea if you've got a bit more time on your hands. Thumbing a lift on a yacht from the US West Coast or Australia's north east is possible for those with sailing experience, or the desire to cook meals and scrape barnacles. Generally, you'll be hooking up with yachties in the USA between May and October as they take advantage of favourable winds and weather conditions. They'll all scatter by late November as the cyclone season fires up. If you're not planning to batten down the hatches with the locals, you probably should scatter with them.
Buses are a great, unpredictable, noisy way of moving about the main islands.
The aiga busses on Tutuila are brightly painted trucks that blast reggae music all day. Never rely on a bus after about 2pm. We encourage you to verify any critical information with the relevant authorities before you travel. This includes information on visa requirements, health and safety, customs, and transportation.
