Getting around Papua New Guinea: trains, buses, driving and domestic flights

Papua New Guinea has no national road network linking its regions, so the choice is not bus versus plane — it is plane, charter or boat, plus a car and driver at each end. The table below matches the common trip shapes to the mode that works.

Prices are 2026 estimates in kina (K). Domestic airfares move with demand and are highest around holidays and the dry-season trekking months.

Start with the flight map, not the road map. Air Niugini and PNG Air cover the main towns, and that is the only practical way between regions. Book the long legs first, then build the ground days around them. Weigh bags carefully: small aircraft have strict limits, and excess baggage is a common reason people get left behind.

Keep a buffer day on either side of any domestic flight. Delays and cancellations are common, and a missed connection can cost a day or more. If your trip depends on a charter to a lodge or a remote airstrip, ask the lodge to book it and to tell you what happens if weather cancels the flight — pack for an extra night.

On the ground, use an operator car and driver. This is how visitors move in Port Moresby, Lae, Goroka and Mount Hagen, and it is usually included in packages or charged at K400–800 a day (2026 estimate). Follow the driver's judgement on road blocks and do not stop for strangers at night.

The Highlands Highway between Lae and Goroka takes 6–8 hours by operator car. It is scenic but exposed to hold-ups and landslides, and armed robbery or tribal fighting can close sections. Check conditions before each trip and travel only with an operator.

For water legs — Sepik canoes, Milne Bay and island hops — use boats with life jackets, two engines and a radio or phone. Seas rise in the afternoon, so morning crossings are calmer.

PMV minibuses are the local way to move and cost K1–3 in town, but they are not recommended for visitors in Port Moresby or Lae because of pickpocketing and robberies on board and at stops.

There is no passenger rail service in the country, so train passes do not exist here. Bus passes do not exist either: PMV fares are paid per trip in cash, and long-distance road travel is not sold as a ticket product.

Road conditions change fast. Landslides, bridge damage and security incidents can close the Highlands Highway and other routes with little warning, so treat any road plan as provisional.

Liquor sales are controlled by province and bans are declared at short notice, which sometimes signals unrest; if a ban appears, ask your hotel or operator what is happening before you travel.

Travel insurance matters more here than in most destinations because a cancelled charter or a medical evacuation is expensive. Check that your policy covers domestic light aircraft and remote-area evacuation before you fly.
