The trail typically begins near the Hermitage of San Bernabé of Ojo Guareña. This is a significant landmark in the area and a common starting point. Parking is generally available in the vicinity of the hermitage, which serves as the main access point for exploring the Ojo Guareña Natural Monument.
The El Ventanón Trail offers diverse terrain, ranging from plains with holm oaks to jagged mountains and gentle plateaus where cattle graze. You'll encounter karstic landscapes with numerous chasms (some fenced for safety) and rocky sections. Some parts may have thick vegetation, requiring attention to trail markers. It's categorized as a moderate difficulty hike, with some demanding slopes and ascents. Be prepared for varying ground conditions and a lack of shade in many areas.
This trail is rich in natural and historical sights. You'll start near the unique Hermitage of San Bernabé of Ojo Guareña, which is built into a cave. The route then leads through holm oak forests and past captivating rock formations. A major highlight is the ascent to Pico del Cuerno, offering panoramic views of the Sotoscueva Valley. The most prominent feature is "The Ventanón" itself, an impressive natural stone bridge often called the "Window of Burgos".
While the trail is generally accessible, it's important to consider the karstic terrain with chasms and potential livestock on plateaus. Dogs are usually permitted in natural areas like the Ojo Guareña Natural Monument, but it's always best to keep them on a leash for their safety and to protect wildlife and grazing animals. Ensure your dog is comfortable with rocky, uneven paths and bring plenty of water for them, especially on sunny days.
The trail can be enjoyed during various seasons, but spring and autumn are often ideal due to milder temperatures and vibrant scenery. Summers can be hot with limited shade, so early mornings or late afternoons are recommended, along with ample sun protection and water. Winter hiking is possible, but be prepared for potentially cold and wet conditions, and check local weather forecasts for snow or ice, especially at higher elevations.
Hiking the El Ventanón Trail itself does not typically require a permit or entrance fee. However, the trail is located within the Monumento Natural Ojo Guareña. While access to the natural monument's outdoor areas is generally free, specific guided tours or access to certain caves or facilities within the monument (like the interior of the Hermitage of San Bernabé or the main cave system) may have associated fees or require reservations. It's advisable to check the official Ojo Guareña Natural Monument website for the latest information on guided visits and regulations.
Yes, the El Ventanón Trail shares sections with several other routes. Notably, 96% of this route is part of the official "El Ventanón" trail. It also intersects with significant portions of the "Merindades Bike Race 2022" (59%) and smaller segments of "Canales de Dulla" (26%), "Asturian Way" (22%), "Sendero Histórico: Burgos" (22%), "Pico Cuerno" (16%), and "El Valle" (9%).
Given the trail's moderate difficulty and varied terrain, it's recommended to bring sturdy hiking boots, plenty of water (especially as shade is limited), sun protection (hat, sunscreen), and snacks. A map or GPS device is useful for navigation, as some parts with thick vegetation might make the path less clear. A first-aid kit is always a good idea, and binoculars can enhance your experience of the panoramic views and wildlife.
The El Ventanón Trail, as described in the tour data, is a circular route. This means you will end your hike at or near your starting point, offering a continuous journey through the diverse landscapes without retracing your steps.
The trailhead is located near the Hermitage of San Bernabé of Ojo Guareña. While this is a significant tourist attraction, facilities like cafes or public restrooms might be limited directly at the trailhead, especially outside of peak season. It's advisable to plan accordingly and use facilities in nearby villages before or after your hike. Always carry out anything you carry in.
The trail passes through the Ojo Guareña Natural Monument, an area rich in biodiversity. You might spot various bird species, and the presence of cattle on the plateaus indicates a pastoral landscape. While specific wildlife sightings can vary, the diverse habitats, including holm oak forests and rocky areas, support a range of local fauna. Keep an eye out for birds of prey soaring above the mountains and smaller mammals in the wooded sections.
circular route Simple, beautiful, comfortable and familiar ride, I recommend visiting the inside, even if you pay, the cave, and especially the hermitage of San Tirso and San Bernabe, spectacular, I also recommend bringing water, the only source on the route is the town of Villamartin de Sotoscueva, and if it is hot it is necessary I copy and paste description, although I did not start it in the parking lot that is in the upper part of the hermitage, but in a small parking lot that is in the lower part The route begins in the parking lot of the Natural Monument of Ojo Guareña, right from there there are already signs that indicate the way to the Ventanon, I went down to the Natural Monument of Ojo Guareña, after visiting it I returned to the parking lot and started the route. A few hundred meters away, there is a fork to the Cuerno peak, which is next to it, a place with good views. Then we go back to the fork again and follow the direction towards the window again, almost all the way to it is in a straight line and it is also very well signposted. On the way we will come across a gate and passing this a fork again, but we continue straight. Arriving at the Ventanon, before a new signal, we turn right and continue in that direction until we reach it. There we can enjoy this natural window that offers us incredible views, it is also a good place to relax and have lunch, it should be said that we must leave the place as we found it, or even better. We resume the route in the direction of Villamartin de Sotoscueva, it is also well indicated at all times, we will go through a Canadian pass and continue along the road to the town. Once there, after visiting whatever our curiosity takes our fancy, we will leave through the opposite part of the town, through an alley that Sandra on our left, here either I did not see it or there was no sign that indicated it, so be careful. As soon as we go up the alley there will be a gate in which as soon as we pass it we must turn right, also be careful because it is not signposted and a path that goes straight could easily confuse us, so as soon as we pass it we look to our right and We will see a small path along which we will continue. Here, as I said, is a path that is also well signposted and in which only by following it there is no possibility of making a mistake, we continue until we find the path that we took to climb to the Ventanon, from here it is only undoing the way to the parking lot and we will be done. The route is very simple and in which the window and the path from Villamartin de Sotoscueva to the parking lot are well worth visiting.
