Cueva de Nerja–Nerja Cave on the Sun Coast of Spain


As I contemplate another gray, chilly day in Maine and gaze out across the snow-covered fields, my thoughts wander to the sunny coast of Spain.  In February of 2011, my mother and I traveled to Torrox on the Spanish Sun Coast to escape England’s dreary winter for a week.  While there we took a local bus to Nerja, (pronounced Nair-ha) just up the coast, to visit a natural wonder of the Andalusia region, the Caves of Nerja.  This underground formation hosts over 450,000 visitors per year.  The photo above was taken from the Balcon de Europa, a vantage point in Nerja, toward the Sierra Almijara, the mountain housing the cave system.c3The mountain range consists primarily of dolomite marble formed on the floor of the Mediterranean during the Triassic period.  Tectonic forces drove the rock seabed into the sky, creating mountains.  Calcium carbonate is a porous stone subject to being dissolved by the corrosive effects of acidic rainwater.  Since the formation of the mountains about 5 million years ago, rainwater has been seeping into cracks in the marble.  Slowly, the water eats away at the rock until great caverns result.  The drip formations (called speleothems) began to take shape in Nerja Cave about 800,000 years ago.

The cave system is comprised of three main galleries that run nearly horizontally for about one-half mile within the southern side of  Almijara Mountain.  The tourist entrance is located 518 feet above sea level.  The interior hollows are between 627-404 f.a.s.l.  One gallery is open to tourists and the drop from the entrance to the lowest floor is about 115 ft.  The ambient air temperature inside the caves averages 64F.  The constant flow of water makes the environment humid.  The cave even boasts a World Record:  the widest naturally formed column, a speleothem 105 ft high and 42.6 ft x 23 ft at the base, and getting bigger every day!  The caves are currently situated well above the water table so there are no lakes inside.  The galleries are divided into halls.  Some of the halls are impressively huge with soaring cathedral ceilings.  One hall has been fitted with stadium seating and a stage where a music and dance festival is held every year.  The hall provides great acoustics.

The caves were discovered in 1959 by five boys who were trying to observe bats.  They had seen the bats exit from a sinkhole, so they crawled inside.  The sinkhole was one of two natural openings into the caves.  The kids explored a bit until they stumbled across two skeletons.  Frightened, they rushed home to tell the rest of the town about the find.  Since then, Nerja Cave has been extensively studied.

Excavations showed humans began to inhabit the caves about 25,000 years ago.  At first they were part-time residents during the fall and winter.  They subsisted on locally hunted prey such as wild horses, cattle and goats.  When humans were not present, hyenas, lynx, birds and bats lived in the caves.  Paintings on some of the walls have been dated to as far back as 20,000 years.  They were etched or painted mostly in black and red and depict the fauna of the times and also geometric designs and symbols that likely had great significance to the artists.  About 21,000 years ago, humans took up permanent residence.  Since the caves are located within two-thirds of a mile of the sea, much of the cave dwellers’ diet consisted of fish and seafood.  They supplemented their meals with rabbit and plants.

Around 4500 BC pottery production began in the caves.  Later, the unique shelter was used to house cattle and as a necropolis.  Neolithic burials, such as the bodies found by the boys, have provided DNA that allows researchers to trace some individuals to an African origin.  The skeletal remains are considered a rich funeral record of Andalusian prehistory.  Many other artifacts such as beads, arrows, fish hooks, other tools, loom weights and pottery have been recovered from the living spaces of the cave.  Around 4000 years ago, the cave was sealed by rocks and sediment, likely from flooding.  All its treasures were conserved until modern times.c7

My mother and I visited on what was for Spain a sunny, warm early spring day.  There were plenty of other tourists around, although the place was not crowded.  The administrators limit the number of people allowed in the caves at any one time.  Because people produce CO2 and moisture as they breathe, their numbers must be within the capacity of the air conditioning system installed in the caves, or their simple breathing would damage the caverns.

There was a soft flow of air at all times when we were inside.  The sound of dripping water was constant.  Flash photography is not allowed in the cave, but lighting has been set up to showcase the lovely colors and forms of the rock flows.  The formation shapes are given names such as macaroni, pineapple, cauliflower, nails, flag or pearls in addition to stalagmites, stalactites and columns.  A substance called moonmilk forms from the detritus carried in the dripping water.  This material builds up in sheltered pockets into a whitish powder deposit that has a pudding consistency when saturated.  Moonmilk has sometimes been used in cosmetics.  Tiny rivulets flow alongside and beneath the walkways in many places.  In several areas, my mom and I both noticed significant changes in air pressure causing popping in the ears and heaviness in the sinuses.  There were many staircases to climb and descend, giving us a thorough workout.

As I reviewed the photos for this article, I noticed several orbs present in some shots.  My understanding of these photographic artifacts is that they occur when a bit of dust is caught in the camera flash, causing a circular burst of light to be recorded.  What I don’t understand is why there are orbs in my photos since I did not use a flash, it was prohibited.  I have enhanced most of the pictures here by lightening them to simulate the flash.  Here is an example of a before-editing and after-editing picture.  The editing program brightened the scene and emphasized the colors present in the rock.c10
c8Here is a photo with several orbs evident.  In the brightest one I can almost imagine a face, with the eyes and nose.  It looks a bit intimidating.  Are these artifacts merely a reflection in a low-light environment somehow generated off specks of dust or are they something different?  Are there energy orbs present?  Only a psychic would know if the spirits of the ancients linger in the caves.  Would it be surprising to find such presences in a place inhabited by so many generations of humans; an underground repository for the dead, no less?  After all, we modern visitors are tramping through their cemetery.  No wonder the orb looks angry!c6

All psychic phenomena aside, the caves truly are an amazing, even spectacular, sight.  They and the nearby town of Nerja with the Balcon de Europa, and the narrow streets lined with quaint shops and tiny eateries are well worth a day trip for any visitor to the Sun Coast.  Here is one last shot, the delicious lunch I enjoyed with my mum after touring the caves.  My meal was a toasted sandwich made with the prized regional dry-cured Iberian ham, olive oil, fresh roasted asparagus, herbs, and tiny quail eggs, with a glass of local rose.  Mums had a fresh tomato and melted cheese sandwich with mango juice.  Delicious!c12

  1. Thanks Mums, it was a wonderful time. I hope we can enjoy more memorable trips. I’m not sure, but it looks like your sandwich might have some salmon on it or some sort of meat? I don’t remember now what you ordered. I do recall it was a yummy meal!
    I didn’t notice any orbs around when we were in the caves and was surprised to see them show up in some photos. I do remember the place felt heavy to me, like many spots in Europe, due to the layers of lives that have occupied the land.
    The more I look at that big orb, the more a face jumps out at me. It looks skull-like.

  2. We had a really wonderful time. I did not see the orb you photographed. Whatever can it be!
    Beautiful photos and well written narrative. Thank you!
