Some 90km northwest of Seville, ARACENA is the highest town in the Sierra Morena with sharp, clear air, all the more noticeable after the heat of the city. A substantial but pretty place, it rambles partly up the side of a hill topped by the Iglesia del Castillo, a Gothic-Mudéjar church built by the Knights Templar around the remains of a Moorish castle. The town is flanked to the south and west by a small offshoot of the Sierra Morena – the Sierra de Aracena – a wonderfully verdant corner of Andalucía with wooded hills and villages with cobbled streets.
Gruta de las Maravillas
Although the church is certainly worth the climb, Aracena’s principal attraction is the Gruta de las Maravillas, the largest and arguably the most impressive cave in Spain. Supposedly discovered by a local boy in search of a lost pig, the cave is now illuminated and there are guided tours as soon as a couple of dozen or so people have assembled; to protect the cave there’s now a strict limit of 35 persons per visit. At weekends and holiday periods, try to visit before noon – coach parties with advance bookings tend to fill up the afternoon allocation. On Sunday, there’s a constant procession, but usually plenty of time to gaze and wonder. The cave is astonishingly beautiful, and funny, too – the last chamber of the tour is known as the Sala de los Culos (Room of the Buttocks), its walls and ceiling an outrageous, naturally sculpted exhibition, tinged in a pinkish-orange light.
