The Gruta de las Maravillas, located in the charming town of Aracena in the province of Huelva, is one of Spain’s most stunning underground paradises. This cave, discovered in the late 19th century, hides a world of unique geological formations that transport visitors to a natural fantasy world. With its spectacular landscape of stalactites, stalagmites, underground lakes, and fascinating galleries, the Gruta de las Maravillas has become one of Andalusia’s top tourist attractions.
History and Discovery
The Gruta de las Maravillas was discovered by chance in 1886 by a local shepherd, but it wasn’t until the early 20th century that it was adapted for tourist visits. In 1914, it opened to the public, becoming one of the first tourist caves in Spain. Since then, it has attracted thousands of visitors, all fascinated by its stunning beauty and the feeling of venturing into a hidden underground world.
A Tour Inside the Cave
Upon entering the Gruta de las Maravillas, visitors are greeted by a cool and humid atmosphere that contrasts with the warm Andalusian sun outside. As you progress through the 1,200 meters of walkable underground passages, the geological formations begin to reveal themselves in all their splendor. The cave is divided into various galleries and chambers, each with its own unique charm.
Some of the highlights include:
- The Great Hall: This is the first chamber visitors encounter at the beginning of the tour. Its impressive dimensions and the magnificent stalactites hanging from the ceiling offer a breathtaking view.
- The Grand Hall of the Naked: Named after the curious formations that, according to popular imagination, resemble human figures. The whimsical shapes of the stalactites and stalagmites create a mystical atmosphere filled with legends.
- The Hall of Crystals: In this hall, light plays an important role, reflecting off the natural calcite crystals that adorn the walls and ceilings. This phenomenon creates a captivating visual spectacle for all visitors.
- The Underground Lakes: Perhaps the most impressive feature of the cave is its underground lakes, fed by natural water seepage. The reflection of the rock formations on the crystal-clear water adds a magical touch to the journey.
Every corner of the cave offers breathtaking views that seem to come straight out of a fantasy film. The lighting installed throughout the tour enhances the shapes and colors of the rocks, creating an unforgettable atmosphere.
Geological Formations: A Natural Wonder
The Gruta de las Maravillas is a true natural museum of geology. Inside, you can admire spectacular stalactites and stalagmites, columns formed by the union of both, draperies (thin calcite sheets that seem to wave in the wind), and curious formations shaped by the action of water and time over millions of years.
The cave’s mineral richness, primarily made up of calcite, aragonite, and other minerals, has resulted in the whimsical forms that decorate every hall and gallery. The constant action of filtered water over the centuries has sculpted this underground landscape, which continues to transform slowly with time.

Visiting the Gruta de las Maravillas is not only a remarkable experience underground but also a great opportunity to explore the charming town of Aracena. Located in the heart of the Sierra de Aracena and Picos de Aroche Natural Park, Aracena is known for its historical heritage and natural beauty.
In addition to the cave, visitors can enjoy the Castle of Aracena, built in the 13th century, or wander through the narrow cobbled streets of the town. The local gastronomy, featuring products such as the famous Iberian acorn-fed ham, is also a great reason to visit this part of Huelva.
