A "different" trip, a shocking experience, because most of the trip is made inside a tunnel, which in its time, was one of the most important engineering works in Europe for its length, scope and human effort that represented (6,000 employees!). They are 5 km under ground (in some places over 130km below), 4.5 m high and 6m wide. The duration is about two hours. The Tunnel of Montclar is also known as La Mina de Montclar.

Claustrophobics and fearful refrain! 

The trek is not difficult, but ...it must have clear ideas. This trip is only allowed when the water doesn't pass through the channel. (We need the authorization of the Channel House of Urgell to do it with an experienced guide). 

At the end of the tunnel, we will go to the town of Montclar. There, awaits us the Castle of Montclar, Heritage Site of National Character. A tour of its dependencies with a guided visit will complete the experience and the knowledge of this important heritage. 

After the guided tour of the castle, a stop for lunch (picnic carried by hikers) and continue on foot to the starting point. 

If you have the whole weekend, we also propose for Saturday, visit the Interpretation Centre "Cultural Space of the Channels of Urgell" where you travel through the history and the evolution of these lands thanks to the water and the fight of the people who lived here...Surely, the visit don't leave anybody indeferent and will grow the desire to know the epic work of the Tunnel of Montclar tunnel and also the Castle that presides the town...This tour is the ideal introduction to the hiking trip on Sunday!  

Equipment required: Comfortable walking shoes, rubber boots, raincoat or anorak and a flashlight. It is also recommended to wear a helmet and spare clothes. 

Duration of the trip: 4 hours. approx. (2h. inside the tunnel). Approx. 15 Km.
