For canyoning enthusiasts, the Trou de Fer on Reunion Island is a must-see, and not just for the faint-hearted. The first complete descent of the canyon, with a 1,000-meter drop, was made by Thierry Krattinger, Stéphane Girard, and Jean-Claude Dobrilla in 1990. Filming took place in very difficult conditions: an aquatic atmosphere, a dramatic void, and mediocre rock in the 300-meter waterfall. The documentary Trou de Fer was selected for competition at the Trento Film Festival in 1992.

Climbing safely is within everyone's reach. Introduction, progression, training, rope maneuvers, sequence of movements, equipment, and high-level practice—everything you want to know about climbing. Accessing the vertical world means learning to read the rock, combining positioning, balance, and self-control, and having fun. Demonstrations by Jean-Christophe Lafaille (high mountain guide) take place in the dizzying scenery of the Vercors cliffs (Presles and Corrençon-en-Vercors) and the Dentelles de Montmirail. Jean-Pierre Bouvier, known as "Mouche," takes you to the magical boulders of Fontainebleau, while François Legrand (world champion on climbing walls) gives you his advice on how to progress.

Caves of Glass is a documentary from director Sid Perou's Realm of Darkness series, focusing on the ice caves of the Austrian Tennengebirge Alps, including the Eisriesenweld and Eiskogelhöhle. It features Austrian speleologist Fritz Oedl, Belgian speleologist Guy Meauxsoone, and Ian "Tommo" White of the Northern Caving Community. First broadcast on Channel 4 on February 15, 1986, it won a Special Mention at the 5th Barcelona International Festival of Esoteric Cinema that same year.

Greenland, the largest island in the world, is unlike any other country. The film recounts the exploration of the Inlandis cavities in Greenland during the summer of 1992. Janot Lamberton, one of the pioneers of these expeditions, ventured, with speleologists and mountaineers, into the moulins, these immense crevasses that tear through the back of the Inlandis, a vast glacier four times the size of France, while glaciologist Louis Reynaut studies infraglacial phenomena. It is obviously not easy to penetrate the depths of the ice and film at a depth of 150 meters in sub-zero temperatures. The light is blue in one of the most fascinating landscapes on the planet, where scientists and explorers collaborate to deepen their knowledge of the Earth.

On the Thessalian plateau, a place famous in ancient Greek history, enormous and steep rocks rise, almost representing an epic clash of giants. In this mystical environment, Meteora once served as an aerial refuge for hermits and then for nuns of strict orders, who, renouncing the world, lived in the celestial peace of the peaks. This area is today a silent and fantastical climbing site, and some caves carved into the rock face remain inaccessible. Mountaineer Patrick Berhault and his French partner Patrick Cordier, one of the classic leaders of modern climbing, have set out to conquer these peaks steeped in history, which will never cease to be "The Pillars of Dreams."
