At the foot of El Penyal d'Ifac, where the path begins, one finds a beautiful pebble beach, Cala El Racó, very close to the Real Club Nàutic de Calp.

Upon reaching the cove, on the left side, it is possible to see a series of buoys: this is where the underwater trail starts. It is about 120 metres long and has five aquatic informational panels located at a depth of approximately one metre.

Entering from the beach and following the left wall, with an approximate direction of 180°, the visitor will discover a shallow seabed where rocks abound on one side and posidonia seagrass on the right. Posidonia is an essential aquatic plant (not algae) characteristic of the Mediterranean Sea. It plays a crucial role in preserving marine ecosystems and our beaches as it contributes to water oxygenation, serves as shelter, food, and breeding grounds for numerous fish, crustaceans, and mollusks, and reduces the force of waves striking against the beach.

Among these posidonia meadows, one can easily find a clear path which needs to be taken in order to veer to the right. In this direction, it is possible to discover the remains of an ancient fishing boat.

Throughout the underwater route, the maximum depth is about five and a half metres at the farthest buoy. Throughout the cove, one can see a multitude of damselfish, groupers, wrasses, gobies, moray eels, sea slugs, saddled breams, salpas, saddled seabreams, and some gurnards. If there is luck, one might spot an octopus, a cuttlefish, or a small squid, and by paying close attention it is possible to even see schools of saurels.
