A cave through which the Chicu flows, a tour about Ice Age wildlife, and trails to mountain pastures or cheese farms showcase the different sides of Onís. For planning, you can distinguish between guided visits, seasonal bearded vulture experiences, and trails with different focuses.

Cave and Ice Age Wildlife

Cuevona de Avín is a cave with a 500 m-long passage and three entrances, through which the Chicu River flows. Inside is the Avín Ice Age Wildlife Interpretation Centre. A guided visit to the centre lasts about 45 minutes. The cave setting thus combines with a cultural activity focused on Ice Age wildlife.

Bearded Vultures: Observation and Exhibition

The guided bearded vulture observation trip visits a feeding station for scavenging birds and a bearded vulture release area. The experience is seasonal; check before your trip whether it is available on your dates. Centro Las Montañas del Quebrantahuesos offers guided tours of a bearded vulture exhibition. This visitor programme may also vary by season. Observing the birds at the locations mentioned and taking a guided tour of the exhibition therefore offer different ways to explore the subject of bearded vultures.

Mountain Landscapes and Circular Trails

Part of Picos de Europa National Park lies within the Onís area. North of Onís, the Sierra del Ibeu rises as part of the Sierra del Cuera coastal mountain range; its summit, Pico Ibeu, is 872 m high and can be climbed. The Ruta de las Majadas de Onís is a circular mountain trail that passes through some of the most important mountain pastures in the municipality. Part of the route runs through Picos de Europa National Park and Biosphere Reserve. When choosing a hiking focus, you can therefore choose between climbing a named peak and taking a circular route through the mountain pastures.

Cheese Trails and Regional Cuisine

The Ruta Quesera Onís is a 3 km circular trail linking cheese dairies, farms, caves and cider presses associated with local tradition. Access conditions at individual stops may vary; check the conditions of the establishment you plan to visit before setting out. The Ruta Quesera de Benia de Onís leads to the Plaza in Benia. There, you can buy and enjoy Gamonéu DOP at shops, cider houses and restaurants; availability may vary by establishment. Despite their similar names, the routes have different focuses: one connects several types of stops, while the other leads to the Plaza and its cheese offerings.

Two specific details answer different questions when planning your day: the approximately 45 minutes refers to the guided visit to the centre, while 3 km is the length of the Ruta Quesera Onís. This helps distinguish a visit of a set duration from the distance of a circular trail.
