From Boltaña cross the Río Ara and take the road towards Lanave. It's a long and winding road through a beautiful and wild landscape. After about 20 km you'll pass the road for Matidero. After again about as many kms you'll find the mill of Escartín at your left next to the road.

The most telling signs are parts of milling stones scattered over the property: just lying there or garding the flowerbeds or incorporated in resting-places or picnic-tables (2, 3, 4).
The pond is filled up with earth and planted with trees (5, 6), but it's still clear that the size was enormous. The Río Guarga isn't a mountain river fed with melting water of the snows and often doesn't carry much water. A huge reservoir made it easier to survive such periods.
A massive wall (7) formed the south wall of the embalse (mill pond).
The watersupply channel arrives at the far end of the mill pond (6). It's easy to follow from here to the capture point. You'll first walk on an earthen dyke, then into a woody stretch (8). Next there is a section longing the river (9) and after some shrub you'll eventually reach the start of the channel (10) with the azud (11, dam). We are now 600 m away from the mill! A tube, lain in the channel, nowadays brings water to the swimming pool.
