Located at the end of a trail winding between the arid hills of Cabo Tiñoso, the blue waters of Cala del Bolete Grande appear to hikers as a mirage. The cove shelters a wonderful underwater world, where seabream, starfish, cardinalfish, and sometimes a small grouper or a stingray can be seen. The perfect spot for those seeking off-the-beaten-track snorkeling.

How to get to the Cala del Bolete Grande snorkeling spot

Cala del Bolete Grande is located in Cabo Tiñoso Natural Park, west of Cartagena. To get there by land, you’ll have to hike about 2,5km (each way) from the surroundings of the village of Campillo de Adentro.

To find the start of the hiking trail, reach first Campillo de Adentro (a 30 minutes drive from Cartagena), and turn left some 100m after the Bar Cantina, towards Camino Bocaoria/Camino Boletes. After 1km, the road turns into a dirt track on which you can continue another 500m before finding a parking lot on your left.

Park your car and continue on foot along the track, then the small path (which follows the dry bed of a torrent) leading to the creek. The hike includes several steep passages in the rocks, so wear good shoes.

Cala del Bolete Grande snorkeling exploration tips

You can snorkel throughout the cala, which can be divided into several areas (the numbers below correspond to the numbers on the map):

1 / The pebble and Posidonia beds extending in front of the beach (↕2-6ft/0.5-3m). Salema, sargo, annular seabream, saddled seabream and gilt-head seabream are common sightings in this area. Pelagic stingrays are often reported here, including in shallow areas.

Purple sea star at Cala del Bolete Grande
The purple sea star, pretty rare, is undoubtedly one of the most beautiful starfish species living in the Mediterranean sea.

2 / The rocky drop-off that edges the south side of the creek (↕10-30ft/3-10m). You will encounter many red starfish on the walls. There are also many small caves at the foot of the drop-off, where cardinalfish are easy to see. Many ornate wrasse twirls in the most oxygenated areas.

3 / The small coves found north of the beach (↕6-18ft/2-6m). It is undoubtedly the fishiest area, where salema and seabream (often seen in schools), damselfish and wrasse are easy to spot.

4 / The surroundings of the islet located a hundred meters from the beach (↕3-30ft/1-10m). Two-banded seabream, painted comber and cardinalfish hide in the crevices on the walls of the islet. By taking a look inside, you might also find a purple sea star, a rather rare species in the Mediterranean.
