Expeditions Unlimited is Secret Planet's very high altitude and polar expeditions activity.

Since 2011, we have been committed to promoting the human dimension of exploration as much as the mental and physical challenge.

Expeditions Unlimited’s explorers and guide are among the world’s best in their specialty. Unassuming about their past feats, they carry within themselves an ethic of exploration. A form of humanism unites them. They offer us extraordinary expeditions, in regions untouched by man, whether it is mainly very high altitude and polar lands, but also deserts or forests on the planet.

We offer the ascent of the fourteen peaks over 8,000 meters, all located in the Himalayas, as well as some handpicked 7,000 meters, sometimes to progress to 8,000 meters, always as exciting expeditions in themselves. We reach the North and South Poles by ski pulka, cross the Greenland ice cap sometimes by ski-kite, carry out tailor-made expeditions in all the polar regions, in Antarctica in particular.

Our complete offer plunges us into the universe of the world’s most esteemed operators where we are unquestionably the only French-speaking travel agency. We assume this responsibility with pride and, above all, with respect and humility: preparation, excellence of our guides and expedition leaders, equipment quality, safety, medical preparation and hotline, weather expertise, live communication for your community… We make these expeditions accessible to enthusiasts and guide them in accomplishing the journey of their life.





Building on our extensive experience from some fifty expeditions, we group and coordinate expertise and skills to help you plan and accomplish your expedition. We are fully committed by your side and by your expedition leader.

To tackle an expedition safely and in full peace of mind, you must be physically and technically prepared. We are there to build with you your progression program. Before your departure, we offer theoretical, hands-on, and medical preparation with your guide and the other participants.

An expedition’s success depends on the right decision being made at the right time. We choose the most experienced expedition leaders and select the local team ourselves. Our expedition gear and material are of the highest quality. We use the services of top-notch weather forecasting and medical experts.
