It is so named because it is located in the middle of Güimil (Vilarmaior) and Callobre (Miño). The river Medio is a tributary of the Lambre, which flows into Ponte do Porco.
It is a small linear route that begins at the edge of the provincial road DP-4804, in the old mini-power station of Güimil and on the border with the municipality of Vilarmaior.
It runs entirely in the parish of Callobre and is well signposted from Ponte do Porco, taking the junction with the national road 651 towards Paderne. This road is very beautiful, and goes towards Vilamateo and Betanzos, bordering the Lambre. The perimeter of the River Medio is a natural environment of great value, with a rich native vegetation. The route between alder, birch, chestnut and oak trees is very pleasant.
First we come across the Lambre bridge, over which the Pilgrims' Route to Santiago de Compostela passes and which we leave on the right.
After at least 6 km, just where a sign marks the beginning of the town council of Vilarmaior is the starting point of the route of the mills of the river Medio, at the mini-power station of Güimil.
From the mini-power station we cross a small wooden bridge to enter a riverside forest next to the river Medio.
As we go upwards we can see the mills. The first one is A Graña, with its recreational area. Less than 100 metres away is the second, called Muíño Albeiro, with several waterfalls, moss greening the stones and trunks, surrounded by ferns and chestnut trees.
Following a water channel we arrive at the third mill, or do Amado.
By means of different bridges we will frequently cross the river Medio.
Climbing some rustic stairs we reach the fourth mill called Miño.
The beautiful surroundings offer waterfalls, lush ferns and, depending on the time of year, even mushrooms and chestnuts.
Depending on the time of year, the path can be wet and the ground slippery. We may come across some fallen trees and some undergrowth, so we recommend wearing long trousers and suitable footwear.
From here we ascend along a forest track to reach a road again, turning left we arrive at the Chapel of Guadalupe.
The route can be converted into a circular route if we go down the asphalted road from the chapel to the starting point.
The mills were restored a few years ago, but due to technical difficulties the roofs gave way and suffered some damage. However, another project for the restoration of the ethnographic complex is pending execution.
