We have very clean water,good visibility, four training lines that can all be set at your target depth, counterweights on our deep training ropes, a sonar fishfinder to watch freedivers underwater and 80m of depth.

Founded in 2003. Saltfree is run by Samphire Amps (nee Kirby). Sam wrote many of the original freedive courses for AIDA and helped develop the PADI Freediving Programmes.  One of the most experienced AIDA Instructor Trainers, Sam is also a qualified teacher, a PADI Course Director and a former Captain of the UK Freedive Team. Sam works extensively with the media, showcasing freediving on television and radio. Our celebrity students have included physiology and nature presenters Steve Backshall, Professor Alice Roberts, Andy Torbet and Nick Baker. Sam and the Saltfree team have also worked with the Royal Navy and BBC underwater film crew to help develop their freediving skills.

If you would like to learn to freedive from scratch, or have done some diving but don’t have a qualification yet – visit our Freedive Courses page to find out how to get started. Our PADI Freediver beginner course only takes a weekend.

If you already hold a freedive qualification and would like to come and train with us, our Freedive Meets page explains how that works. If you’d like to progress your diving, we run courses all the way up to PADI Instructor level. Visit our Freedive Courses page for info on that.

  • “I spent a day training with Sam in glorious south coast seas last summer. We managed to do lots of exercises, a fair few extended exploratory swim-throughs, and the day culminated with a 20m max dive. Sam was relaxed, good company and a terrific teacher, I’d recommend her to anyone.”–Steve Backshall, BBC Live and Deadly – Freedive Cornwall Training Day

  • “My students were amazed. Their level of enjoyment and consequently ours was much higher due to the quality of the equipment and the clarity of the site and water. We also did a session on the various sunk items: container swim through, metal tube, helicopter, plane, armed tank – good to have fun as well!”

    –Jean-Fabrice, AIDA Instructor

  • ‘I started Freediving by doing my beginner course with Sam at Saltfree in 2005. Since then I have become a competitive freediver on the International freediving circuit, and completed an Instructor course with Saltfree. Saltfree has given me a fantastic space to learn and develop my freediving.  If I were going to do it all again from the beginning I wouldn’t change anything about my freediving education with Saltfree”– Liv Philip, UK Record Holder and UK Team Freediver

  • “80m deep, great set up, awesome safety equipment / people, and a pontoon so big you can jog laps to keep warm in the winter! There is nowhere like the emerald green depths of Chepstow.” – Tim Money, UK Team Freediver

  • “People often wonder why I love freediving at Saltfree. I love the first moment when I immerse myself into the water. I love the community of freedivers I meet and most importantly the warmth & support which we bounce off each other, to help us to safely push our limits.” – Kayleigh Relf, Freediver

  • “Very welcoming community of people and instructors intent on providing excellent training and safety. The facilities provided at the NDAC are second to none” – Adam Mustoe, Advanced Freediver 

  • “Doing the 4* has really helped with my technique. Sam is extremely knowledgable and was able to answer every question, even going into detail using medical textbooks!  Almost immediately after completing the course I did my first 40m dive. There’s no way I would have been able to do this before the course; it’s helped me overcome a barrier and I’m quite excited about the possiblities for the future.” – Pete Barnes, AIDA 4 Star

  • “A fantastic way to spend a weekend, being educated, inspired and welcomed to the challenging world of freediving. Reaching that plate’s a great feeling!”– Rich Minshaw, Beginner Course
