Bajo de Dentro is a rocky submerged pinnacle located in the Islas Hormigas marine reserve off the tip of Cabo de Palos in Murcia. The marine reserve consists of 19 sq km of protected water characterized by an extremely high diversity of aquatic life.
The pinnacle consists of a rocky outcrop which rises up from a sandy seabed at around 50 metres and reaches a depth of around 3 to 4 metres. Its northern side comprises of a gently sloping platform
some 20-30m in length which lies in 12-16m of water. Both the eastern
& western sides consist of steep walls and the easterly wall is
almost vertical & deeper.
We dived with the Naranjito scuba diving centre from the port of Cabo de Palos in a RIB. Bajo de Dentro lies exactly 4 km from port, within the
marine reserve of Islas Hormigas taking around 10-15 minutes to get there.
Because
of the currents that surround the pinnacle as well as its coveted protected marine reserve status, Bajo de Dentro is extremely rich in both marine flora and fauna. Large schools of both
sea perch, Chromis, Corva, Bream & Mojarra are guaranteed, which in turn attract
shoals of Barracuda, Groupers & Dentex. Amongst the rocks lies
sanctuary for Scorpion fish, Brotala, Lobsters, Moray and Conger Eels.
There is also an abundance of soft corals such as Gorgonias. You can
occasionally spot eagle rays, sunfish & maybe turtles.
Common marine life: large groupers, moray eels, eagle rays, barracuda shoals, dentex, sun fish, slipper lobsters, bream, blennies.
Visibility: From 10 m to 40m Min depth: 4m Max depth: 50m Experience level: Open water and above Conditions: This
site is situated in open waters so can be affected by some strong currents and a north easterly wind.

Jelly fish, Pelagia noctiluca, aka mauve stinger.
This jelly fish's sting was quite painful. During the diving season I regularly saw this species in the water around Murcia. I managed to successfully avoid its sting. However one day on climbing into the boat I did feel an extremely sharp pain on my ear lobe. At first I thought my ear-ring had been ripped out. The sensation was close to what I imagine the pain would be from a hammer strike on my lobe and an anvil!
There are two large chambers within the Devil's Cave. The first at the entrance was completely submerged whereas the second was filled with air and accessible through a tunnel running vertically to the surface.
The second chamber was impressive. There were numerous remains of candles which would have made the cave even more spectacular, however, the effect of our torches also offered its own alluring experience.
The Skylight Cave was one of my favourite dive sites.
With the opening directly above the cave system almost the whole cave was illuminated. On entering the cave, divers proceed to the middle of the cave below the skylight. The area on the far left of the diagram was unlit and required the use of torches. The group could then swim up at the back of the cave and surface in the top left corner. It is possible to stand in this area but with great care, many plants and organisms lived in this area and it would be a shame to recklessly crush them. The group could then swim back towards the skylight and swim down to the lower level.
A conger eel was regularly found in a crevice at the back of the Skylight Cave.
Part of the dive included showing the other divers the conger, if he was at home.
The Devil's Cave was known as one of the best dive sites so all the divers were excited and anxious to enter and explore the cave. The conditions that day were favourable and the divers in the group all had enough experience and no hesitations regarding diving in caves. I can just be seen at the far back of the group in the video.
The Big Cheese is near the port of Cala Ratjada.
It's a big rock that rises from the water and is riddled with holes
giving it its name. This was without doubt the best dive site in the
area for spotting sea life: octopus, barracudas, lobster, nudibranchs,
moray eel sightings are guaranteed.
