Néal waterfall and view of the pond. There is work in progress, so the water level is exceptionally low due to a drain.

Directly near the Ille-et-Rance canal, the 3 km tour of the pond allows everyone to indulge in hiking, horse riding or cycling. In season, the restaurant and supervised swimming offer the possibility of spending friendly moments with the family.

Indeed it is quite sporty and since the path is not often used, you have to avoid brambles, nettles and fallen trees. The point of view is worth the detour on the other hand, an azure or even green water 👍

A beautiful pond around which it is good to walk. The trail is very accessible and many wooden footbridges allow you to walk and get as close as possible to the banks of the pond.

⚠️ Black mountain bike trail. Not recommended for beginners. Need to carry the bike in places or even do a little climbing (meaning: trail also not recommended for mountain bikes such as VAE or (some) DH anvils).
