Buceo La Restinga, 38917 La Restinga

El Bajón (★4.6)

It is surely the most famous dive in the Canary Islands and one of the most important in Europe. Submarine volcano that emerges from nowhere and stays about 9 meters deep from the surface. Giving us a landscape unmatched anywhere in the world.
Mares, Janez Kranjc

La Herradura (★4.4)

There are two buoys of the marine reserve on the plateau of Herradura. This buoy is located on the limit between zone C and B of the marine reserve, there is no diving allowed in zone A. On the plateau are lots of canyons. This place tends to be exposed to currents, then it’s not suitable for beginners.
Buceo La Restinga, 38917 La Restinga

Playa La Herradura (★4.2)

One of the essentials of the Marine Reserve !! Located right in front of “El Bajón“ and just two minutes away from La Restinga port. It is one of the dives that have more life and also does not touch much depth.
Scubapro

Punta Restinga (★4.4)

We descend to a fairly flat platform at around 20 meters and continue until we reach the edge of a drop-off that falls below 40 meters in some areas. Along the wall, there are caves and crevices. We ascend along the wall back to the plateau, passing through several canyons on the way to the mooring point.
Buceo La Restinga, 38917 La Restinga

El Rincón, El Hierro (★4.4)

This is the first and closest site to the port of La Restinga, from the bollas of the Marine Reserve, Mar de las Calmas. As soon as you leave the eastbound port, this site is just 100 meters from the entrance and just 20 meters from the outside of the port.
Buceo La Restinga, 38917 La Restinga

Puerto de La Restinga (★4.2)

It is where we always do the nights, the diving courses and baptisms. It enjoys an incredible cleanliness of its waters. La Restinga beach is in the same place and has received the “blue flag“ for the purity of its waters.
Mares

El Río (★4.3)

We begin the descent at less than 10 meters deep and gradually reach greater depths, crossing several rock ridges and adjacent ravines. As we go deeper, the seabed becomes more uniform with wide sandy patches. A cave in shallower waters is well worth a visit.
Mares

El Coral/Punta del Río (★4.3)

We gradually descend along a lava tongue that borders a light sandy bottom on its eastern side. As we ascend along the western side, we can explore the nooks and crannies of the rock, especially in the shallower area.
Aqualung

Hoyos del Feo (★4.1)

We follow a ravine west of the mooring point that gradually gets deeper. We reach a vertical wall with a small cave just beyond 30 meters. The seabed next to the drop-off is composed of fairly light-colored sand.
Buceo La Restinga, 38917 La Restinga

Punta las Cañas (★4.0)

Punta las Cañas, near the integral reserve (place of maximum protection), is an easy dive, although sometimes we can find some current, almost always heading east.
Buceo La Restinga, 38917 La Restinga

Baja Bocarones (★4.4)

A very special and beautiful dive that is not always accessible because of the strong wind that is always on the island. It is not within the Marine Reserve, but it is as if it was!
Buceo La Restinga, 38917 La Restinga

Cueva del Diablo (★4.4)

“La Cueva del Diablo“ is very shallow and very easy. You go to a kind of large cave that is reminiscent of a church vault. It is very spacious with very nice sets of colors
Mares, Janez Kranjc

Piedra Bermeja (★4.3)

We move along a seabed of sand and rock toward the roques, circling around them. The most impressive part is the open sea side, where we reach a breathtaking vertical wall. We then ascend to a platform at around 15 meters, and finally return to the mooring point through a narrow passage that leads us back to the s
Buceo La Restinga, 38917 La Restinga

El Salto, El Hierro (★4.5)

Beautiful immersion without currents and quiet, where we will enjoy some beautiful games of colors with small caves and a very special circuit...
Extra Divers El Hierro, 38917 El Pinar de El Hierro

Barco Chino (★4.5)

Through a big rock gate, you will reach a plateau at 18m deep with two towers near the edge. An exciting dive with lots of holes, caverns, and swim-throughs. Landscape diving at its best!
Extra Divers El Hierro, 38917 El Pinar de El Hierro

El Desierto (★4.3)

This is the last and furthest of dive sites in the Mar de las Calmas Marine Reserve heading west, and it will take 10-15 minutes to reach from the port of La Restinga.
Mares, Predrag Vuckovic

Playa Brava (Cueva de Arena) (★4.7)

From the small cove where the boat is moored, we descend to a rocky seabed reaching depths of 20–25 meters. Back near the mooring area, we find the most interesting feature of this site: a fairly large cave about 25 meters long, located at just 8 meters deep.
Buceo La Restinga, 38917 La Restinga

Baja Fria (★4.4)

Close to the coastline the slope leads to a drop-off starting at 20m, after dropping down to your max. allowed dive depth you start ascending to a plateau at 6m where you can pass a small swimm-through before doing your safety-stop.
SCUBA SUR, 35120 Arguineguin

Ray Bank, Gran Canaria (★3.8)

A large number of concrete sculptures (cubes, tubes, pyramids) form a great habitat for quite some sea life. The sandy bottom forms a great contrast with the sculptures.
SCUBA SUR, 35120 Arguineguin

Artificial - Block3 (★3.9)

A large number of concrete sculptures (cubes, tubes, pyramids) form a great habitat for quite some sea life. The sandy bottom forms a great contrast with the sculptures. One of the 5 sites of the Artificial Reef.
SCUBA SUR, 35120 Arguineguin

Artificial - Block2 (★4.2)

A large number of concrete sculptures (cubes, tubes, pyramids) form a great habitat for quite some sea life. The sandy bottom forms a great contrast with the sculptures. One of the 5 sites of the Artificial Reef.
SCUBA SUR, 35120 Arguineguin

A large number of concrete sculptures (cubes, tubes, pyramids) form a great habitat for quite some sea life. The sandy bottom forms a great contrast with the sculptures. One of the 5 sites of the Artificial Reef.

Artificial (★4.3)

A large number of concrete sculptures (cubes, tubes, pyramids) form a great habitat for quite some sea life. The sandy bottom forms a great contrast with the sculptures. One of the 5 sites of the Artificial Reef.
SCUBA SUR, 35120 Arguineguin

Salobre Reef (★4.0)

The Salobre Reef is an extension of the beautiful Pasito Blanco Natural Reef. The long, approximately 2 meter high wall is home to a lot of wild life. On the sandy bottom you can find rays (eagle rays, electric rays and stingrays) and sharks.
SCUBA SUR, 35120 Arguineguin

Pasito Blanco (★4.3)

The dive spot of Pasito Blanco is situated about five minutes from the sports beach in Pasito Blanco at the south of the island. The sea floor is like a rectangular morphology up to 60 meters long and 16 meters wide. A visit to Pasito Blanco to explore all the nooks and crannies can reveal a whole variety of life.
