The Pan-American Highway
Prudhoe Bay to Ushuaia — the longest road in the world. Most people drive a section; a few do it all. This is the open-ended framework for either.
Prudhoe Bay to Fairbanks
The Dalton Highway runs 666 km (414 mi) of mostly gravel from the Arctic Ocean, crossing the Brooks Range at Atigun Pass and the Arctic Circle on the way down. There is fuel at Coldfoot and nowhere else. Most rental contracts forbid it outright, which is the first of many times this trip will be easier to start than to arrange.
Alaska into the Yukon
From Fairbanks the Alaska Highway runs south-east to the border at Beaver Creek and on through the Yukon — Kluane's ice fields on one side, and the longest stretches without a settlement on the whole route. Fuel range matters more here than anywhere until Patagonia.
British Columbia to the Lower 48
South through the Cassiar or the Rockies depending on how much time you have. Jasper and Banff are the postcard route and priced accordingly; the Cassiar is emptier, rougher and better. Cross into Washington and the character of the drive changes within an hour.
The American West
There is no single Pan-American route through the United States, and the argument for going west is the Cascades, the Sierra and the Colorado Plateau. Budget more time than feels reasonable for the desert parks and less for the interstates, which are fast, dull and unavoidable in the middle.
Crossing into Mexico
The border is the first real bureaucracy: a temporary vehicle import permit with a deposit, Mexican liability insurance bought before you cross, and a tourist card. Cross early in the day at a quieter post, not at Tijuana or Nuevo Laredo. Then the character of the whole trip changes for the better.
Down the Mexican spine
Toll roads make good time and cost real money; the free roads are slower, prettier and pass through towns. San Miguel de Allende, Guanajuato and Oaxaca are where people who planned a week end up staying a month. Do not drive at night — that is the one piece of advice everyone here agrees on.
The northern triangle
Guatemala, El Salvador and Honduras come in quick succession and the borders take hours rather than minutes — fixers, copies, stamps for the vehicle as well as for you. Lake Atitlán and Antigua justify the paperwork; El Salvador's coast road is the surprise of the section.
Nicaragua and Costa Rica
Granada and Ometepe — an island of two volcanoes in a freshwater lake with bull sharks in it — then into Costa Rica, where prices roughly double and the road quality does not improve to match. Check current advice on Nicaragua before committing; conditions there have changed more than once in recent years.
Panama, and the gap
The road ends at Yaviza. The Darién Gap is 106 km (66 mi) of roadless jungle and there is no legal, safe overland way through it — this is not a challenge to attempt. Vehicles go by container or roll-on ship from Colón to Cartagena, typically four to seven days and well over a thousand euros; people fly.
Colombia
Collect the vehicle in Cartagena and expect the paperwork to take a day or two more than promised. Then Medellín through the coffee axis to Cali, on mountain roads that climb and drop thousands of metres between cities. Colombia is where most drivers report the trip stopped being an endurance test.
Ecuador
Small, cheap and vertical. The Avenue of the Volcanoes runs south from Quito past Cotopaxi and Chimborazo — whose summit, because of the equatorial bulge, is the furthest point on the surface from the centre of the earth. Fuel here is among the cheapest on the continent.
Peru
The coastal Panamericana is fast desert driving between oases; the sierra route through Huaraz and the Cordillera Blanca is slower and far better. Do both if you can: down the coast for the Nazca lines and Paracas, up into the mountains for Cusco and the Colca.
The Bolivian detour
Not on the official Panamericana and worth the diversion regardless: La Paz, the Salar de Uyuni, and the lagoon route south to the Chilean border at Hito Cajón, which crosses passes above 4,800 m (15,700 ft). Diesel is sold to foreign vehicles at a higher tariff and receipts are required.
Chile's long spine
Down from the Atacama — the driest desert on earth, and the clearest sky for it — on Ruta 5, which runs 3,300 km (2,050 mi) with Santiago and the wine valleys in the middle. The Chilean border is the strictest on the continent for agricultural goods; empty the fridge before you reach it.
Patagonia to Ushuaia
Two ways south and both are legendary: Argentina's Ruta 40 across the steppe, or Chile's Carretera Austral on gravel through rainforest. Either ends at the Strait of Magellan, a ferry to Tierra del Fuego, and the sign at Ushuaia that marks the far end of the longest road in the world — some 30,000 km (18,600 mi) back to where you started.
Good to know
The stages above are a framework, not a schedule. Six months is the common figure for the full run and the range people actually take is four months to several years — the variable is not distance, it is how long you stop.
The budget below is one month on the road, not the whole trip. Multiply it by however long you intend to take, then add the Darién shipping as a separate one-off: a container or roll-on sailing from Panama to Colombia usually runs well over a thousand euros per vehicle, plus flights for the people.
Documents run the trip. A carnet de passages is not required in the Americas, but temporary import permits are issued at almost every border and must be cancelled on exit or the next country will refuse you. Keep a folder of vehicle title, registration, insurance and twenty photocopies of everything.
Direction is a seasonal decision. Southbound means starting in Alaska in June or July, which is the only window the Dalton is comfortable, and arriving in Patagonia around the southern summer — the two hardest ends of the road at their best. Northbound reverses both and is the harder sell.
This is one of the few routes where a vehicle is the whole point, but it can be done entirely on buses. Central and South America have dense, cheap long-distance networks; the parts that genuinely need your own transport are Alaska, the Yukon and Patagonia.
Shorter or longer?
Mexico to Panama only — the Central American section, where the borders are dense and the distances short.
South America alone: fly into Cartagena and drive or bus to Ushuaia, skipping the Darién shipping entirely.
The full run with the detours that make it worth doing — Baja California, the Guatemalan highlands, the Bolivian altiplano and both Patagonian roads.
