Welcome to Byw’n Iach Arfon, Caernarfon

We have a 25-metre Swimming Pool and a Teaching Pool, with lessons for children and adults to build confidence and skills. We offer a wide programme of fitness classes for all abilities, along with a fully equipped Fitness and Weights Room and a functional training area for strength and performance.

We are also proud to be an official affiliated HYROX Training Centre, supporting members to train for the international HYROX fitness race.
