What's the plan?

We have several amazing hikes and activity options in Sierra del Montsec. Depending on the weather conditions, we’ll decide on the best option for each day. Here are all the possible hikes.


The Congost de Mont-rebei is an impressive gorge that forms the natural border between Aragón and Catalonia. The impressive path digged inside the rock allows us to walk right next to the cliffs enjoying breathtaking views on the turquoise water reservoir, just as if we were flying just above it.

 13km aprox. + 500m gain of altitude
We will discover the Camarasa reservoir from the impressive cliffs of “Els balconets” where it's possible to observe eagles and the famous bearded vultures. This panoramic route will take us through bunkers of civil war, a beautiful reservoir and to a small "Ermita" where we'll enjoy stunning views.  


14km - + 630m gain of altitude

A beautiful gorge far from the crowds, a river, some very cool walkways and a peaceful hike with stunning views are the ingredients of this unique route. 



 10 KM + 430m gain of altitude 

A charming town on the shore of a beautiful reservoir and surrounded by beautiful red mountains. 

PARAGLIDING IN AGER (optional + € 110) 

An unforgettable paragliding flight baptism. Let’s go for a tandem flight starting in the  Montsec with an elevation gain of between 600 and 1050 meters. Depending on the thermals (ascending air currents caused by the action of the sun), we will enjoy the sky between 15 amd 30 minutes. 


NIGHT WITH THE STARS (optional + € 17) 

Thanks to its very low luminous contamination and to its meteorological conditions,  
the Montsec is considered one of the best places in the world for astronomical observation.  Let’s enjoy the star’s lights and go for a night visit to the Parc Astronòmic Montsec including an explanation of the night sky with a telescope.
