Deserts, ice, altitude, jungle

Expedition

An expedition is not a longer holiday. It is a trip where the environment sets the rules, the margin is planned rather than hoped for, and every litre, every hour and every spare part has to be justified before you leave. This is the department where the arithmetic gets serious.

The four environments in this department punish different mistakes. The desert punishes optimism about water and fuel. The cold punishes moisture and complacency. The jungle punishes speed. Altitude punishes hurry.

Read the environment that scares you most first. The planning discipline transfers even when the kit does not.

All stories in Expedition

Expedition · Desert Crossing a Sand Sea Is an Arithmetic Problem Fuel, water, heat and days. Get the four numbers right at the kitchen table and a desert crossing is a magnificent, orderly experience. Get one wrong and it becomes the other kind of story. 10 min read

Expedition · Polar Cold Is a System, Not a Jacket At minus thirty, everything that worked at home behaves differently: diesel, batteries, plastics, hands and judgement. Winter travel is the discipline of managing moisture and time. 9 min read

Expedition · Jungle The Green Wall: Travel at Walking Pace In tropical forest, distance stops meaning anything. Twenty kilometres can take two days, everything you own is wet, and the vehicle is only one part of the problem. 8 min read

Expedition · Altitude Thin Air: What Altitude Does to People and Engines Above 3,000 metres your vehicle loses power, your stove struggles, your sleep breaks up and your judgement quietly deteriorates. All of it is manageable, and all of it needs planning. 8 min read

Which environment pulls hardest?

Questions we get asked

How much water per person per day?

In moderate conditions with cooking and basic washing, four to six litres. In heat above forty degrees with physical work, eight to twelve, and dehydration begins before thirst does. Always carry a reserve you have decided in advance never to touch except in an emergency.

Do I need a satellite communicator?

Anywhere you would be in serious trouble waiting a day for help, yes. A two-way messenger with a scheduled check-in beats a beacon that only works once, because most incidents need advice and a change of plan rather than a helicopter.

Is one vehicle enough?

For established routes with traffic, often yes, with good recovery equipment and self-recovery skill. For a genuine crossing far from a track, two vehicles are the difference between a breakdown and an emergency. If you must go alone, halve your ambition and double your margins.
