Gape at the size of Grotte de La Verna, a capacious 4 hectare (12 acre) cavern in one of the largest cave systems in the world, extending 250 m (820 ft) wide and 190 m (623 ft) high. It's part of the Pierre Saint-Martin massif, which features 2,000 chasms--including a dozen or so reputed to be among the largest in the world.

    We chose the visit with as goal the ascent to the Lepineux well. We were not disappointed. Accompanied by Jeff, our guide, fascinated by the abyss of the Pierre St. Martin, we have enjoyed the overall standard of this cavity dimensions. We also learned a lot about the history of this network. This tour is for people accustomed to evolve off-trail, but it's your case if

    After 660 m of horizontal tunnel, hole in the cave, very dimly lit for better to deceive our senses. Lifting the head looks to be outside under a cloudy sky. Once informed, we take the measure - or rather the excessive - to the place. It's extraordinary, gigantic, you become ants! Provide warm clothing (5 degrees and icy draught in the tunnel). Excellent explanation of the guide for this tour "exploration River".

    We opted for the visit "Discovery" one hour thanks to which we have access directly and only to the large room where you feel tiny. Provide warm clothing as it is 5 ° C! Too bad because we had more time we would have tested the sports tour! Very professional guide and interesting.

    Surprising, nothing in common with the caves j visited. Here no stalagtites and stalagmites but 83 hectares with a startling vault room. Several more or less sporty exploration opportunities! I recommend!

    I didn't think that at age 55 I am able, I did it! With attention, coaching, and the kindness of Jean François, my friends and I did visit Aranzadi without encountering major difficulties. almost "fingers in the nose". Worth the visit, it's beautiful. Thank you Jean-François to share this passion with the public that we are. Bordeaux/Chilean
