How we teach freediving

Despite the fact that the history of this sport originates from record attempts and therefore from the extreme search for depth, for us, freediving today is something else: an activity oriented towards psycho-physical well-being that can be practiced by adults and children in close relationship with the sea element.

Katabasis Freediving and Sailing is constantly striving to create a professional and fun environment by guiding its students towards the gradual discovery of their own underwater skills, simply by using their senses, which are often forgotten in everyday life.

In all freediving courses we practice descents along the cable, which are essential for developing technique, and ample space is given to the practice of sensory and recreational freediving with particular attention to knowledge and active respect for the delicate marine environment.

Participation in the courses includes a certificate of participation from Katabasis Freediving and Sailing or, on request and on reaching the standards, the international SSI Freediving certification.

Breathing, relaxation and stretching will accompany you on this incredible journey towards a better lifestyle!
