Learning about birds is more rewarding in settings like this, as it's suitable for all ages and especially valuable for children's learning. We're talking about a small sustainable tourism adventure, an exploration of the world of ornithology through pure observation, without any direct interference with the species being observed.
The Güena River
The area surrounding the Gueña River, a pure, oxygenated river that originates in the peaks of the Picos de Europa mountains and flows into the Sella River , boasts a rich environment . In Onís, the section of the river designated for birdwatching has allowed for the restoration of an old, disused local path, making it ideal for beginners in this activity, as it is barely over a kilometer and a half long.
A space that we will traverse without haste and with the respectful disposition that this type of observation demands; the "visual hunt" for a great variety of birds : woodcocks, dippers, green woodpeckers, robins, blackcaps, blue tits, tawny owls, thrushes, great tits and many other specimens typical of these ecosystems; as is also the grey heron , that solitary bird that we can discover in the waters of the river at any time of day, feeding on fish, amphibians or insects.
The ornithological route
The route, included in the Onís municipality's Tourism Sustainability Plan, begins in Tullidi , a tourist and environmental information center adjacent to Benia de Onís, which also houses the Bearded Vulture Mountains Interpretation Center . This center is well worth a separate visit to learn more about the birds, their behavior, and their biology. From here, the path runs alongside the river. We immediately notice the abundance of wildlife that appears at every turn. Binoculars will be very helpful for observing the birds in detail, but it will also be essential to maintain an attitude of patience and anticipation throughout the route. The aim here is not to complete the hike in a specific time. On the contrary, it is about leisurely enjoying a small enclave of nature brimming with sensory rewards.

The trail has been equipped with bird feeders, observation points, and specific viewing areas, as well as information panels explaining everything that surrounds us and that we can clearly see; and many other things that surround us but that we will only discover with careful attention. In addition to birds, we are provided with information about the local insects, the native flora and fauna, and the tree species found in the riparian forests and their surroundings. For example , the ash tree , that deciduous tree of the olive family, is highly valued by shepherds for its elastic and resistant wood used to make tools, and its leaves are also used for livestock fodder or to make infusions to treat colds.
On our way we will also find a water mill, once very common throughout the Cantabrian coast, which took advantage of the water currents to turn it into a mechanical force for sharpeners, fulling mills and from the XNUMXth century, with the introduction of corn, for grinding. of the grain.
