It all started when a digger drilling in the center of Tarragona discovered a huge cave. A quarter of a century later, with numerous explorations in between, the Cova Urbana can be visited, guided by the Societat d'Investigacions Espeleològiques de Tarragona (SIET).
The excursion is worth it. It passes through a Roman gallery (200 BC), several lakes and huge caves. The visitor ends up in the mud almost up to the eyebrows, but also full of surprise that such a large cavity under the urban area exists. The tour starts from an underground parking garage in the middle of the city. You don't have to travel to the Pyrenees to go spelunking.
The itinerary of the visit is explained in detail on the page www.siet.cat, with an email and phone numbers to book a tour. In total, about 300 meters of galleries are covered.
The research continues and new galleries and cave chambers are still being discovered. The photo at the very top of this BLOG shows the Rivemar room that is still under investigation. 2,000 m has already been discovered, but it could eventually be 5,000 m2.
The tour takes about 3.5 hours and is reasonably safe according to the SIET. Visits are only possible during the weekends. Children must be 10 years or older (and taller than 1:50 m).
