Our Story

From a Novel to a Trekking Agency

Lost Horizon — the name — comes from a 1933 best-seller in which author James Hilton describes a utopia set in a Tibetan lamasery hidden in a fertile valley deep in the mountains: Shangri-La. Today, several towns in Tibetan areas claim to be "the real Shangri-La" — Zhongdian in northern Yunnan even changed its official name to Shangri-La to boost tourism, while the Yading reserve in Sichuan, with its three sacred peaks brushing 6,000m, makes its own case. We make no claim to have found the "real" Shangri-La — but it's exactly these places, and the sense of myth and possibility they carry, that we want to share.

Our trekking agency was founded in Kunming, in the southwest of China, in 2015, by a French team that has now lived, guided and travelled across West China for well over a decade. From the Yunnan hills to the deserts of Inner Mongolia, by way of the high passes of Sichuan and the Tibetan plateau in Gansu and Qinghai, we've built our routes on the ground, one trek at a time.

How We Work

Designing & Running a Route

A French-Chinese team · routes walked before they're sold · safety taken seriously

A team that knows both sides

Route design is led by team members who understand both the terrain of West China and the expectations of European trekkers, working alongside Chinese guides, drivers and local families who make each trek possible — from homestays in Pumi villages to camel handlers in the Badain Jaran desert.

Every route walked before it's offered

All our itineraries are scouted and re-walked by the team itself. We adjust difficulty and pacing to the season, the weather and the group, and keep refining accommodation, resupply points, daily distances and the overall experience.

Safety comes first at altitude

Several of our routes spend days above 4,000m. A portable altitude chamber is available on demand for high-altitude treks, and our IFREMMONT-trained mountain-medicine correspondent means we take acute mountain sickness seriously — from acclimatisation pacing to knowing when a consultation before departure is worth arranging.

Our Products

Four Ways We Work With You

Signature Treks Across West China

Seven routes through Yunnan, Sichuan, Gansu, Inner Mongolia, Tibet and Qinghai — from moderate village-to-village walking to full high-altitude expeditions above 4,000m — each one designed to combine into a longer 2–3 week journey.

High-Altitude Expeditions & Trekking Peaks

Beyond our signature treks, we support trekking-peak ascents and logistics for expeditions in Sichuan and Qinghai — transport, porters, cooks and administrative support in a part of the world where logistics can otherwise be genuinely difficult to manage.

Cycling Tours Across the Himalaya

Beyond trekking, we also design cycling expeditions across some of the highest roads on Earth — including the legendary Lhasa to Kathmandu route, crossing the Tibetan plateau and the Himalaya by bicycle.

Tailor-Made Journeys

Family trips, private groups, or a fully custom itinerary built around a region or a season you have in mind — if you have a specific project, we're glad to design it with you.
