CoSMos – The Salmon’s Odyssey


Once upon a time, there was…
A legend, a great voyager, a migration….
A wonderful and fascinating fish...
An extraordinary adventure in the natural world, the king of the river!

CoSMos – The Salmon's Odyssey, a unique space in Belgium, invites you on a journey along the path of this fish and the incredible trip that it accomplishes, from its birth and up until the final beat of its gills!
Thanks to the hard and devoted work of the Fisheries Service officers, this space, which had completely disappeared from the Ardennes waterways, is back.
The site is accessible upon reservation only.

Once upon a time, there was a formidable odyssey!
