La Leze, a spectacular descent that crosses the Sierra de Altzania underground. One of the best canyon in hte Basque Country.
La Leze Cave is a large cavity 80 meters high, which crosses from north to south the Sierra Altzania massif. A cave carved out of limestone rock with abundant fossils. Unique in Europe for its geological characteristics, with only 7 caves in the world.
The origin of this cavity is found in the natural outlet of the water from the valley on the other side of the mountain, known as the "Hoya de La Leze", where our descent down the river will begin. The Artzanegi river, which crosses the Altzania mountain range from one side to the other, made its way through the karst system, transforming into an underground river that has its natural outlet at the entrance of the cave in the municipality of Ilarduia, Álava.
There are several waterfalls that are recorded inside the endokarst to bridge the large gap between the entrance and exit mouths. Enter the gap carved by the Artzanegi river and cross the mountain avoiding all the difficulties that we will encounter in our path.
Jumps, rappels, descents, etc. that we will carry out in the most absolute darkness, only altered by the light of our frontals. More than 6 rappels between 3 and 25 meters in length that will put our skills and balance to the test. 2 jumps of about 3 meters high where we will show our courage and cold blood. 3 fun slides will give us the perfect combination for a cocktail that will refresh all our instincts.
Enjoy the descent of La Leze, a ravine dominated by the roar of the water and the embrace of darkness.
