Lanterne river, A river in eastern France

Lanterne river is a modest waterway running across eastern France, from the Mille Étangs plateau down to the Saône. Its banks are lined with trees and low brush, and the current moves at a gentle pace, splitting into several small channels in places.

For centuries the river shaped local farms and villages, with old channels used to power mills that ground grain or cut wood. A ferry accident in the 1700s, when several people drowned, is still remembered as a reminder of its hidden strength.

The river's name comes from an old word meaning "slow," which matches the way it drifts through fields and woodland. Local people still come to fish, walk, or pause by the water, and you can see small signs in nearby towns that mention its place in daily life.

Walking paths and small bridges make it easy to move along different stretches of the bank, with grassy spots for sitting. The flow changes with the seasons, so the water runs higher in winter and spring while summer brings a slower, lower level.

Near its source on the Mille Étangs plateau, the river begins among hundreds of small glacial lakes that slowly feed the first channels. You can stand where the trickle from those ponds becomes a proper current, which is a sight most visitors miss by staying downstream.
