The Río Manubles rises in the Dehesa del Tablado of Borobia. Its river landscape, routes through the municipality, historic buildings and astronomy experiences offer different focal points for planning a trip.

River Landscape and Trails Around Borobia

Borobia’s forests include holm oaks, Portuguese oaks, oaks, junipers and rockroses; broom and juniper bushes also grow in the undergrowth. The Sabinar de Ciria y Borobia also shapes the landscape: its wetlands are home to tree junipers, Portuguese oaks and Montpellier maples. There, the Río Manubles forms a gorge with numerous caves inhabited by griffon vultures.

Laguna Gandalia lies in a former mine and is recommended for birdwatching and recreation. Those interested in exploring the landscape on foot or along other routes will find several different route descriptions. The GR-260 Vuelta al Moncayo, also known as the Calcenada, runs for 14 kilometres through the municipality. It can be travelled by mountain bike, on foot or on horseback.

The GR-86 Soriano crosses Borobia from north to south, starting at La Cueva de Ágreda and ending in Ciria. The PR-95 Ruta de las Yeseras is shorter and designed as a local circular route: it leads from Borobia to former gypsum works on the border with Aragón. Another guided route runs between Borobia and Ciria through the Sabinar de Ciria and the gorge of the Río de las Cuevas.

Observatory and Guided Experiences

The Observatorio de Borobia offers a range of astronomy activities. Information from the observatory dated 25 March 2026 lists guided visits by day and night, with online booking. Check current dates and booking options before planning your visit.

Two telescopes are used for the guided daytime solar observation. The Coyote telescope is a 16-inch Smith-Cassegrain with a Thousand Oaks filter for observing the photosphere. The 72-millimetre Icaro solar telescope is used to observe the chromosphere, or lower atmosphere.

At full moon, El Rayo de Luna combines telescope observations of the lunar surface with a poetry recital and a reading of a legend by Gustavo Adolfo Bécquer. Astrosenderismo por el Moncayo, meanwhile, combines hikes around Borobia with identifying constellations with the naked eye and learning how to navigate at night.

Another guided activity is the observatory’s historical double walk, which lasts an hour and a half. It runs through Borobia to Mina Gandalia and Huerta de la Virgen and is reserved exclusively for groups of more than 20 people and schools. Topics include the Gandalia iron mine and its 60-metre-deep lake, the botanical surroundings of the Ermita de la Virgen, with their Celtiberian influences, and Borobia’s history. This includes Tristán de Luna y Arellano, who was born in Borobia and was a conquistador and Florida’s first governor.

Buildings, Traditions and Regional Cuisine

The Ermita Ntra. Sra. de Todos los Santos is said to date from 1200 and was apparently rebuilt in the 18th century. The Ermita de Nuestra Señora de los Santos is surrounded by Huerta de la Virgen, a botanical garden with European trees and plants. The Iglesia de Nuestra Señora de la Asunción was built in the 16th century in the late Gothic style and incorporates early Plateresque forms.

The Castillo Medieval de Borobia is a ruin with surviving remains of walls, paving and masonry. It was a residence of the Castilian marshals Luna and Arellano. During the Carnaval de los Zarrones, the Zarrones parade through the town and throw straw at people who provoke them. This pastoral tradition is part of Borobia’s cultural and ethnographic heritage.

Mantequilla de Soria is also part of the local character: Borobia is one of the municipalities in the province of Soria where it is made. The municipality describes it as a product with a protected designation of origin.
