North of Treffendel, Etunel pond is a large body of water appreciated by locals and tourists alike. On the sometimes tight tracks that border its shore, be vigilant when cyclists are busy mountain biking. During capricious weather, a small wooden cabin built at the eastern end of the pond provides rest.
