Meet your instructor 100 meters from where you will be entering the water. Listen to a safety briefing and then receive your mask, snorkel, fins, and wetsuit. Before entering the water, you will listen to an introduction about the natural environment of the area. Hear about the history of the area, its volcanic origin, and the biodiversity you will encounter while snorkeling. Once you have learned how to use the equipment correctly, the guide will accompany you on an itinerary designed to observe the three types of marine ecosystems existing in the Cabo de Gata Natural Park. First, explore one of the best-preserved Posidonia meadows in the entire Mediterranean, which shelters hundreds of different species. Next, explore underwater caves, and narrow gaps in the rock that you can swim through. These formations are thanks to the recent volcanic activity of the area. Then continue to the third distinct area. Since underwater fishing is prohibited in this environment, most of the fish will not be frightened by your presence, so you can observe them up close. The guide will be watching out at all times for the safety of the group, warning you of any possible dangers and ensuring you feel safe and comfortable. When your guided snorkeling experience is over, swim back to the original meeting point to return your equipment.
