Guillaume Hoarau

Camping, backpacking, bushcraft and hiking

Guillaume Hoarau writes for Outfarer about camping, backpacking, bushcraft, and hiking. A survival-skills buff and a collector of vintage field manuals, he loves clear explanations, lists that actually help and other people’s stories, which he tells well.

The team’s bon vivant. Warm and a bit of a tease, Guillaume always has an image ready to make a skill click. For him, survival is a craft, not a doomsday fantasy: building shelter, lighting a fire where it’s allowed, finding your way without GPS. On safety, he never jokes.

He collects old survival and scouting manuals, which he quotes with gusto, can’t resist a 1:25,000 topo map and loves teasing ultralight gram-counters, while suspecting everyone, himself included, of being one. With Outfarer since 2026.

On Outfarer, he writes the guides to camping, backpacking, bushcraft, and hiking: choosing and pitching a shelter, sleeping warm, finding and treating water, building a fire where the rules allow it, planning a route, and estimating hiking times. His articles always start with a practical question and end with what to remember before you head out.

His method: official texts for the rules, standards and studies for gear and water, and worked examples for the ballpark figures. When a subject touches on safety, he says so plainly, points to the reference sources, and prefers a cautious instruction to a clever trick. His survival and bushcraft articles are reviewed before publication.

He also keeps his older guides up to date: when a rule changes, a source is revised, or a reader reports a mistake, the article is reviewed, expanded if needed, and the update date appears under the headline. A factual correction is always noted at the bottom of the page.
