Had the most amazing time. I did this solo, everyone was friendly and kind. Food was amazing, the days were jam packed with things to do and no pressure there if you didn't want to. Have rebooked for another already

Was a really fun trip and met so many nice people! Rich, Mel, Emma, Frith and Becky were so helpful as I was a beginner swimmer but put me at ease straight away and helped me in the water. Highly recommend

This was my third time coming on the trip and once again it did not disappoint! All of the staff were brilliant, supportive and caring. The activities were fantastic, cakes fabulous and the food was great. The accommodation was comfortable. It was great to meet the other swimmers and share experiences with them, in an environment where I felt empowered and supported to have a go. Thanks again!

Another fabulous break with this amazing company. The weather , admittedly, helped but they have a unique ability to make you feel your on holiday with a group of friends, the food is brilliantly done so you don’t feel you’re overeating but are constantly full (special mention for Mel’s cakes especially the Millionaires Shortbread - TO DIE FOR) and with non processed food!
The swimming as ever was the highlight - always safe, lovely locations and measured for all. The other activities walks and talks were all interesting and no pressure to be ‘always present’ if you needed a bit of lone time.
Just working out what I can do next year…..
