Grey water and cassette: emptying a campervan
How much water to carry, how to keep the tank clean, where to empty grey water and the cassette, which products to use, and what dumping can cost.
Trail running, snow, water, nature and destinations
Nolwenn covers trail running, snow, water, nature and destinations for Outfarer. Curious about everything, from meteor showers to night-train timetables, she has a knack for unearthing the one detail that changes everything, and putting it in a single sentence.
The team’s livewire: endlessly curious, enthusiastic, idealistic, and a touch rebellious beneath her impeccable manners. Nolwenn is as thrilled by a starry sky as by a well-found train timetable, and will always pick a precise fact over a brochure superlative.
She knows the meteor-shower calendar by heart, collects European night-train timetables and follows mountain weather the way others follow football. With Outfarer since 2026.
On Outfarer, she writes about trail running, snow, water, nature and travel: preparing for a first trail race, choosing a waymarked snowshoe route, knowing where to find the mountain weather forecast, watching the night sky or wildlife without disturbing them, and reaching the start of a walk by train rather than by car.
Her method: official sources for rules and safety, published data for distances, timetables and seasons, and always precision rather than hype. She points out what changes from one country to another and what depends on the conditions on the day, so that you set off with reliable benchmarks rather than brochure promises.
She also keeps her articles up to date: when a timetable, an access rule or a season changes, 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.
