Casla: Hiking Trails, Karst Landscape and Cultural Heritage

Casla combines hiking trails, a limestone landscape and religious cultural heritage. When planning your stay, you can choose from different focuses: routes through the landscape, the history of the churches or the patron saint festivities in September.

Hiking Routes of Different Lengths

The Senda del Caslilla is a 7.10-kilometre hiking route connecting Casla and Sigueruelo and passing through the Parque Natural Sierra Norte del Guadarrama. Along the route are riverside landscapes with limestone cliffs, gorges and caves, including the Cueva del Ranchón.

Another route is the Senda de los Pastores: it is 154.90 kilometres long and also passes through Casla. The stated lengths represent two clearly different scales—a connection between two places and a much longer route. When planning, you can first decide which route you want to include in your trip.

Karst Landscape and Starry Skies

At the foot of the Sierra de Guadarrama near Casla, limestone shapes the karst landscape. Its features include caves, rock overhangs, sinkholes and underground rivers. The Río Caslilla rises within the municipality of Casla, providing another geographical connection to the town.

The starry sky is also connected with Casla: the Senda de los Pastores is certified by the Starlight Foundation for the quality of its night sky. The municipality is also home to the Mirador de estrellas, which belongs to the network of stargazing sites in the province of Segovia. Casla therefore offers two different points of interest for travellers interested in this subject: a certified route and a viewpoint in the provincial network.

Churches and the History of the Town

The Iglesia de San Pedro Apóstol stands in the town centre. Its presbytery, the church’s sanctuary, unusually faces north. This distinctive orientation is a specific architectural feature that brings together local history and church architecture.

The Ermita de Nuestra Señora de la Estrella is Casla’s patron saint chapel. It stands among juniper trees and elms at the foot of the Sierra. Until around 1665, the Virgin associated with the chapel was venerated as Nuestra Señora del Estepar. This earlier name offers a historical perspective on the religious tradition connected with the chapel’s present name.

Another testament to Casla’s history is the Cañada Real Soriana Occidental, which runs through the municipality. It is linked to the town’s transhumant past and shows that the landscape also has a history of seasonal livestock migration.

Patron Saint Festivities and Travel Planning

The patron saint festivities in honour of the Virgen de la Estrella take place every year from 9 to 14 September. The municipality offers residents and visitors an extensive cultural programme; dates and activities may vary from year to year. If the festivities are important to your trip, check the specific dates and programme in advance.

Casla is located on the N-110, a useful reference point when planning your journey. When looking for hotels in Casla, you can start with the reason for your trip: hiking routes, the karst landscape and starry skies offer different focuses from the town’s history or the September festivities.
