Oscuros del Vero is located in the
Sierra and Canyons de Guara Park in Aragon province of Spain in Pyreneen Mountains. Oscuros del Vero is the begining of the long aquatic trip of
Canyon del Vero. After a pleasant walk on the river into the beautiful Garganta de Lecina percied by thousand alcoves, the Rio Vero lost to sight into a great chaos of huge fallen blocks. These megaton boulders result from the colapsed part of the roof of a colossal natural bridge. This impressive natural bridge is totally oculted from the river by the huge pile of rocks so few people on the trip are aware to swims under it. It is also extremely difficult to reach the natural bridge from the oscuros. A small but intersting
pierced pothole is also located on the oscuros section.
