Best snorkelling spots in Mazarron

Home / Blog Eng / Best snorkelling spots in Mazarron

Few sensations are as beautiful and accessible as snorkeling. Put on your snorkel equipment and dive into the sea to discover its bottoms and its life. Visiting a completely different world within reach of a couple of swims. Especially if we are talking about the Mazarron’s bay area, with a wide biodiversity that populates its rocky bottoms or its posidonia meadows.

Here you will find some of my favorite places to dive simply with goggles, snorkel and fins. In our Mediterranean Sea you will only need to wear a wetsuit in the colder months or for longer dives. All the places I propose are easily accessible, ideal to enjoy even if you have little time and just want to disconnect being part of the underwater world for a while.

Lighthouse area – Cala del Moro Santo beach

Parking in front of the Cafeteria el Faro, we take the path that goes towards the statue of the Sacred Heart of Jesus (also known as the Saint) and shortly before reaching the stairs that go up we turn left to take the path that leads to the cala. To access the beach you have to go down the last section of the path, about fifteen meters a little steeper.

Of all the places I am going to mention, this is the one with the most complicated access. Even so, it is quite easy. And it is very worthwhile.

Once we reach the small cala (very small, it is about eight meters wide and, depending on the sea tide, almost nothing long) we will have access to the sea through the rocks. When we start swimming we will find the beach itself quite interesting and when we are coming out of it towards the sea we can take two directions: to the left or to the right. To the left (facing the open sea) will take us along the cliffs on which the lighthouse is located to the breakwater of the fishing dock with its large blocks that house a good amount of life between their holes.

If, on the other hand, we decide to turn right once we leave the cove, we will go along the cliffs and observe the life that its walls and bottoms harbor as far as we want to go.

The lighthouse area is quite exposed to the sea and is not recommended if there are waves or wind forecast.

La Isla beach towards the Lighthouse

With very easy access, we enter the parking lot of La isla beach and on the left we will see a picturesque neighborhood of small houses distributed irregularly facing the sea, on the slope of the mountain. We drive towards it and park in front of the sea. We will be in the Gachero, a beach formed with the “gachas” (black stones that are actually remains of the smelting of metals) that were thrown from the foundry that still retains a small ruin at the top of the mountain. In ten steps we can access the sea, being careful not to slip on these stones.

Once in the sea, we will go to the left, towards the area of the lighthouse again. We will find a very particular sea bottom formed by the peculiar round black stones mixed with the natural rock formations. If we continue fluttering about 500 meters, we will arrive to a hidden cove, quite particular since it is formed only with these black stones. The sea with its force has been accumulating these stones in a corner of the cliffs forming this peculiar beach.

Cabezo de la Reya

If we want a short but interesting snorkeling excursion, this is a very good option. Leaving from the Bahia beach, we swim to the left side where we find the Cabezo de la Reya, which allows us to go around the hill while we explore the bottom that we will find under the cliff that supports the beautiful viewpoint of the Reya.

Swimming a few meters further, we will reach the breakwater of the yacht club, where we can explore the nooks and crannies between the characteristic concrete blocks that make up this construction.

Cabezo del Castellar

Between the Nares beach and the Castellar beach, you can find the Cabezo del Castellar, a large mountain that enters the sea and is joined to the land by a small tongue of sand.

Easily accessible through either of the two sandy beaches, diving around the hill is always a good option for any day, because even on days when the wind blows a little, we can be sheltered on one of its two sides.

El Rincón beach – Punta Cueva Lobos (Bolnuevo)

In general, all the coves of Bolnuevo are worth visiting. However, most of them are sandy bottom or have little depth.

My proposal for snorkeling in this area is to leave from Rincon beach (which is the first of the coves and has very good access by wooden stairs) to the Punta de Cueva Lobos and go along it. The beginning of the cove we will find rocks and sandy and algae bottoms with little depth. As we move towards the Punta we will find more depth and more life near the rock walls that enter the sea.

If we are in good shape we can swim to the cave that gives its name to the point, a wide but shallow cavity that is said to have once sheltered a good population of sea lions (monk seals).

Cabezo del Mojón

This large rock that goes into the sea like the Castellar hill and serves as a milestone to mark the borders of the municipalities of Mazarrón and Cartagena. Surrounding it is a good dive, it is full of cavities and its walls are home to all kinds of marine life.

In addition, the two beaches that are right next to it are rocky, which provides a very interesting bottom to explore. It can be accessed from the Mojón side of the beach or from the other side through the Rosa de los Vientos urbanization.

Isla Plana

Isla Plana is a small urban settlement between Puerto de Mazarrón and La Azohía. It takes its name from a small island with little relief (a flat island) that is located a few meters from the shore and can be reached by swimming a few strokes.

Going around this island or snorkeling in its surroundings is a good excursion and not too long. It has very easy access, since we can access the sea after crossing the small promenade that runs parallel to the road.

Punta de La Azohía

You got to cross all the village of La Azohía until you reach the church and the Almadraba fish market. You can park in the surroundings (there is not much parking space in summer) and walk to the little harbor in front of the church, entering the sea by one of the surrounding beaches.

The waters of the Azohía are especially crystalline since it is sheltered from the levante (east wind that is common in the summer days, although it is soft) so the experience of diving in this area is quite pleasant.

Be careful as the area is an anchorage for small boats and there may be some boat traffic in and out. If we get to the Punta we will find quite deep bottoms, but probably plagued by large schools of fish close to the cliffs.

Basic recommendations for snorkeling

Snorkeling is a fairly simple and accessible activity, which does not mean that you do not have to follow some recommendations to enjoy the experience properly.

The first and most obvious recommendation is to know how to swim properly. In most of the snorkeling sites there are bottoms that can go from two to eight or even ten meters, depending on the visibility.

Check the weather forecast before going to the sea. If there is waves and / or wind there may not be good visibility, and it can be even dangerous. In the following link you can check the wind and the sea conditions: https://www.eltiempo.es/costa-calida

Although you can do something only with goggles and tube, it is highly recommended to use fins. The fins provide stability to our body while swimming on the surface and also allow us to dive and approach the bottom efficiently if we see fit.

It is necessary to observe the recommendations applicable to any outdoor sports activity such as staying hydrated or protecting yourself from the sun and sudden changes in temperature (for example, when entering the water it is advisable to do so slowly and progressively).

Sea sustainability

At the same time, we must be aware that we are entering the marine ecosystem and we must do our best not to alter it, thus making our activity a sustainable practice.

Some basic recommendations would be:

-Do not leave plastics behind or litter: it seems obvious, but it is easy to find the label of diving goggles on some bottoms.
-Do not disturb the marine life; for example, do not try to catch or manipulate shells, starfish, octopus or anything else you will see. In the sea we are like guests in someone else’s house.
-Do not step on delicate bottoms, such as posidonia meadows.
-Do not tear anything: avoid taking “souvenirs”, especially if they are alive.

If we want to live the adventure of “capturing” something, we can take a submersible camera and capture beautiful images. Or we can take a small net where we can deposit the small plastics that we capture. Collecting plastics can even become a fun game, besides collaborating in the maintenance of a clean and healthy marine ecosystem. You will be surprised by the amount of plastics you will find in the most hidden places. Labels and packaging of products that are no longer even manufactured or that the currents bring from distant countries. We can all do something to improve our environment!

I hope this article will help you to enjoy Mazarrón’s seabed as much as we enjoy it. We will be happy to hear your underwater experiences in Sosiego Hostal de Mar!
