In Valle De Carranza, underground formations, nature and cultural topics, and routes with clearly identified points of reference sit side by side. This makes it possible to plan your itinerary around your own interests: with a guided cave visit, themes related to nature and the underground world, a palaeontological perspective, or a tour of the architecture of the returning emigrants known as Indiano. The routes differ mainly in their starting and end points; in local cuisine, traditional sheep’s cheese adds a distinctive touch.

Caves and nature topics

Cueva de Pozalagua leads into an underground world of stalactites, stalagmites, sinter formations and helictites. All visits are guided; independent access is not permitted. If you plan to visit the cave, check before travelling whether tours are being offered. This makes the cave a clearly defined itinerary item, intended to be visited with a guide.

Parketxe Armañón has a different focus: its permanent exhibition covers local fauna and flora, native breeds and the underground world. A virtual flight and a 3D experience underground complement the exhibition. Unlike the cave tour, several topics are presented side by side here; the underground world provides a link to Cueva de Pozalagua, while fauna, flora and native breeds are additional areas of focus.

Terrasauro at BBK Karpín Fauna offers a palaeontological perspective. The camp presents dinosaur species and their way of life, which visitors can learn about together with four researchers. This makes it different both from the underground formations of Cueva de Pozalagua and from the permanent exhibition at Parketxe, which focuses on local nature and the underground world: at Terrasauro, dinosaurs and explaining their way of life are at the centre.

Routes and culture in Concha

The Ruta Megalítica de Armañón connects the hamlet of El Suceso with Parketxe Armañón; signposted access points and trail markers are part of its infrastructure. The project documented in 2024 presents the route as a cultural itinerary close to nature, featuring 14 monuments.

Two other routes can be distinguished by their connections to Concha. The circular route ENK22 Karrantza: Concha-Lanzasagudas connects Concha with Lanzasagudas. The Karrantza-Balgerri-Ordunte route also starts in the hamlet of Concha, but heads south towards Balgerri. The names indicate different directions without implying a connection between the two routes. If you plan to take one of the routes, check the current conditions before setting out.

The guided tour El sueño indiano also starts in the hamlet of Concha in Karrantza Harana. It introduces the history and architecture of the houses of returning emigrants known as Indiano. Here, the focus is on built heritage, while the Ruta Megalítica explores cultural themes and those connected with nature. Check the applicable booking conditions before your visit.

Local culinary tradition

Karrantza’s culinary tradition includes produce from horticulture and livestock farming. This includes traditional sheep’s cheese made with local milk. This connection to local production adds a distinctive regional focus to excursions.

When choosing between a cave, exhibition, palaeontological camp, tour and route, it helps to first decide on your preferred focus. The experiences described offer different themes and formats: guided visits, exhibitions, a tour of the architecture, and routes with designated points of reference. This makes it possible to tailor a stay to your interests without combining the different destinations into a single circular route.
