The Beni Add Caves: Subterranean Wonders
Descend into the cool depths of the Beni Add Caves, an ancient natural marvel featuring breathtaking stalactite and stalagmite formations.
While Tlemcen is renowned for its historical monuments and Islamic architecture above ground, hidden beneath the earth lies one of the most spectacular natural wonders in North Africa: the Beni Add Caves (Grottes de Beni Add).
A Prehistoric Marvel
Located about 15 kilometers south of Tlemcen in the commune of Ain Fezza, the Beni Add Caves are estimated to be over 65,000 years old. They have served as shelters for prehistoric humans, hideouts during various conflicts throughout history, and are now a major attraction for nature lovers and geologists.
The caves were “rediscovered” and explored by speleologists in the late 19th and early 20th centuries, though they had been known to locals for millennia. The cave system is vast, but a 700-meter section has been made accessible to the public, offering a safe and awe-inspiring journey into the earth.
Formations of Stone
As you descend into the caves, the temperature drops noticeably, remaining at a constant 13°C (55°F) year-round. You are immediately greeted by a breathtaking array of speleothems—stalactites hanging from the ceiling and stalagmites rising from the floor.
Over tens of thousands of years, water seeping through the limestone plateau above has deposited tiny amounts of calcite, slowly building these incredible formations drop by drop. Some of the most famous formations have been given names based on their shapes, such as “The Sword of Emir Abdelkader,” “The Statue of Liberty,” and “The Camel.”
The “Hall of the King”
The highlight of the tour is the vast chamber known as the “Hall of the King.” This enormous cavern is filled with towering columns where stalactites and stalagmites have met. The acoustics in this hall are remarkable, and guides often demonstrate the musical qualities of certain stalactites by striking them gently, producing resonant, bell-like tones.
Legend has it that the caves once connected all the way to Morocco, though this remains part of local folklore. What is undeniable, however, is the profound sense of time and the artistry of nature that one feels when wandering through the Beni Add Caves. It is a stunning contrast to the sunlit, bustling medina above, adding another rich layer to the Tlemcen experience.
