Route through the Natural Park of Lake Sanabria

He Sanabria Lake It is the largest freshwater (non-artificial) surface of the Iberian Peninsula. Natural Park since 1978 is one of the most visited areas of Zamora in summer since the lake is navigable and suitable for swimming. Of glacial origin, in addition to being the largest is also the deepest, who knows if our monster of Lake Ness You are in Sanabria.

The natural park does not contain a single lake, but a large number of them of different sizes. Moreover, this route never contemplates Lake Sanabria but the rest of the lakes in the area. Many of them leave small streams that flow into the main lake.

Route through the Natural Park of Lake Sanabria

The route we make, like many others, we draw at the foot of the map, without obtaining a reference from any other place. Our starting point begins at the Fish Lagoon, located at the end of the road towards San Martin de Castañeda, past Lake Sanabria.

Vega del Conde reservoir

In this lagoon there is a parking in which we can park the car. It has no loss, since the road ends right here. From this same lagoon, we can see below the Mares Lagoon. I recommend your visit in summer since there are a lot of San Antonio Frogs, right in an area that closely resembles a marsh (Laguna de las Cubillas).

Lagoon of the Ventosa

We begin our route on foot of parking, bordering the lagoon by the south and following a stream channeled by man. From here we will take a path that will take us to a couple of frozen lagoons. One of them is called the Lagoon of the Ventosa, located below 1900m.

It is a totally flat area and from this point we can see the top of the Moncalvo, our destiny. A medium top of about 2100m high.

Vega del Conde reservoir

We will start down to Vega del Conde reservoir, below 1600m As we can see, there is a walkable dirt track for all-terrain vehicles, but closed to the public. We will take it to the left, until we see a stream that comes out on our right. This stream is nourished in part of the Laguna del Lacillo, located at the foot of the Montalvo.

The Vega del Conde reservoir filled the sadly famous water Vega del Tera Reservoir, whose walls were broken in 1959 killing 144 people in the town of Ribadelago.

Bordering the Lagoon on the left side and bypassing all kinds of puddles, we arrive at the foot of the Montalvo skirt, already completely covered with snow. We can attack this peak from many positions, most of them of little difficulty.


We chose an area from which a couple of runners came out, quite funny. The snow was very soft so it was not necessary at any time to use crampons and ice axes. The only inconveniences were the continuous sinking to the knees that arose at each step we took.


We reach the top of the mountain and from here the slope would be quite smooth to the top. As an anecdote during this journey, it was to find us a small bird resting on the snow and which had died from the cold a few minutes ago, since it was still hot.

Minutes later we reach the top of the Montalvo, in the place where a geodetic point resides. Of course, there is a small mailbox where we can sign in a book and comment on our experience.

Moncalvo Peak

From here there is no choice but to return to the starting point, going down the mountain ridge to reach the opposite side of the Laguna del Lacillo. We may get a little wet feet, since we will not stop jumping coils one after the other. From here we will cross the path before followed, and it would be enough to return by this until we reach the parking lot of the Fish Lagoon.

What to wear

In winter it is advisable to take warm clothes, leggings, hiking boots, crampons in some cases and even a ice ax. Everything will depend on where we move. In summer it would be advisable to take water, sunscreen and a swimsuit in case we wanted to take a dip in some lake. However, even if we go in winter, there are always areas where snow is scarce and we can walk without complications. Let's not forget that at Fish Lagoon He climbs by car.
