Associated centre on Lake Bolsena
Katabasis Lago di Bolsena is an affiliate centre in the province of Viterbo, in the Lazio region, which promotes freediving focused on well-being, in line with the vision of Carlo Boscia, founder of Katabasis Freediving and Sailing, and with full respect for the sea and all aquatic life. The freediving we offer focuses on awareness of our bodies and our breathing, technique and the pleasure of being in the water, without the desperate quest to surpass depths, distances or times.
Katabasis Lake Bolsena operates mainly on Europe’s largest volcanic lake. With a depth of 151 meters, crystal-clear water, the setting of its wonderful islands ‘Marta and Bisentina’ and the breathtaking panorama of the Volsini Mountains, it lends itself perfectly to a unique freediving experience.

The centre is run by Andrea Viola, a freediving instructor, personal trainer and professional with experience in sports training and nutrition.
ACTIVITIES ON OFFER
SSI Pool/Freediver Level 1 Course
An introductory experience to discover freediving and learn the technique, breathing and the basics of equalisation, but above all to understand and love the water. Open to anyone keen to give it a go, including boys and girls aged 12 and over! Guided step by step by a highly experienced instructor, you will learn the importance of safety and how to practise recreational freediving whilst interacting mindfully with the aquatic environment.
SSI Freediving Advanced Level 2 Course
This course provides further knowledge for practising freediving. It explores equalization in greater depth, covering various descent techniques along the line such as constant weight and free immersion (arm-assisted descent). A course designed to refine your technique without ever losing sight of the fun.
Private lessons
Where students can improve their freediving technique, body position in the water, breathing, and all those small mistakes that prevent them from improving their performance or feeling comfortable in the water. Personalized training sessions, both in and out of the water, to regain or improve physical fitness.
Group or individual Autogenic Training sessions.
Perfect for becoming more aware of your body, achieving deep relaxation and reducing anxiety.
