The odyssey of water and biodiversity!
The visit takes place in several stages (to be organized freely): discover the museum area, take part in the Hydrogame and visit the hydroelectric power station (visit to the power station on registration at Mountanêo reception, included with your admission ticket - offered by EDF).
The first stage of your visit is to discover water, hydraulic energy and the industry present in the Orlu valley. An immersive, interactive Hydrogame (included with your ticket) will help you understand the challenges and benefits of this energy!
Continue your visit with a play area for young and old alike: a first play area to stimulate your thoughts and senses, and a second area dedicated to children aged 3 to 12, offering them a simple, fun approach to the water cycle and mountain biodiversity.
Next, enter the reserve house: a lively, immersive space where a discovery trail awaits you. Explore the different natural environments of the Orlu reserve, its flora and fauna, and put your senses to the test: experience the mountain before you discover it, in real life!
We also invite you to discover the Orlu hydroelectric power station: the only power station that can be visited in Ariège (visit of the power station on registration at Mountanêo reception, included with your entrance ticket - offered by EDF).
> HYDROGAME: Thrills guaranteed!
20 minutes to deal with incoming emergencies! In this race against time, every second counts and your success depends on your ability to work as a team and think fast. Ready for adventure?
