Bioasis Extreme

The Bioasis Extreme Mission is an excellent low cost and low carbon alternative to an overseas school expedition, fusing adventure and conservation with a 60 km self-supported wilderness trek!

Planet Earth is in crisis and you are called to take part in a secret, rebel mission: assemble a team, trek for four days across remote terrain, locate The Bioasis and establish contact with survivors of the advanced expedition. Then, guided by your Mission Leader, you’ll need to solve a series of tasks and challenges to start the process of rewilding our dying planet. Without mobile phones, teams will have to dig-deep to problem solve as a team in wild country and fully embrace off-grid living.   


This 10-day UK adventure is a full-on immersion into outdoor learning and personal development with a tough trek, exciting adventure challenges and conservation projects. Are you up for the challenge?

Bioasis Basecamps

The Bioasis has two main basecamps, each fully equipped with sustainable energy sources, comfortable multi-occupancy tents, a field kitchen, mess tent, composting toilets, bucket showers and a fire pit area. The location of basecamp may change depending on the seasons and the current threat from local industrialists. Potential locations include:


Holbe Meadow Camp (pictured left) lies to the west of the estuary, tucked away between a beautiful wildflower meadow and ancient woodland. The bird life, bees and bats here are magical, as are the stars at night.


Yarnin Fort Camp is situated at almost the highest point in The Bioasis, in a wildflower meadow, and has commanding views across the valley and down to the estuary. Witnessing dawn here is truly special.


Orche Wood Fly Camp is a no-frills expedition camp hidden at the very heart of The Bioasis and surrounded by ancient forest and salt marshes. It’s secluded, atmospheric and a real gem of a location.
