What people are saying!

  • "Our time in the water with Katie was simply magical! She is the most welcoming and loveliest instructor, who’s completely attentive to your needs. The experience itself was incredible, and even though I’m a complete snorkelling novice I was surprised how quickly it took me to feel at ease and simply enjoy the wonderful underwater world around us! We can’t wait to get back in the water! "
  • "I think you already know this, but... I had a brilliant time!! I wouldn't have even got in if it wasn't for you, and now I can say I'd happily go in without tutoring. It's amazing what an hour (well, a bit more thanks to your generosity!) can do for confidence in the water. Thank you."
  • "An amazing experience for both of us - Thank you for sharing your knowledge and passion of the sea and for making us feel safe and comfortable in the water. We saw so much we were not expecting to and we can’t wait to go again. Thanks again and hope to see you soon - happy bubbles!!!!"
  • "From start to finish, our snorkelling experience was perfect. I must admit, I was a little apprehensive but Katie made me feel comfortable and calm. I went along with my 10 year old daughter and Katie kept an eye on her while I was gaining my confidence! We learnt so much about the sea, snorkelling and the beautiful seaweeds. It was a truly magical experience with a wonderful lady. Thank you! xx"
  • "Absolutely lovely, magical Snorkel, the seaweed is like swimming through a fantasy world. Katie found us spider crabs, beautiful jellies and lots of wrass. So good to be snorkelling after nearly 4 years of not diving. "
  • "Wonderful. My boys and I had a brilliant hour snorkelling with Katie. Her knowledge of the area, the conditions and the sea life we would see was superb made the session something none of us will forget. Thank you Katie. "
  • "Our first time snorkelling and what an amazing experience it was, we both enjoyed it so much. Katie who runs the snorkelling experience is lovely and you can learn so much from her. Would recommend booking a snorkelling experience with Katie. "
  • "Amazing experience - a new world under the water. If you aren’t sure - give it a go - can’t wait to return - thank you Katie x"
  • "Had the most amazing experience snorkelling with Katie. She is so knowledgeable on the beautiful plants and animals and her enthusiasm is catching. This is a must do as it was like being in an underwater fantasy garden, the colours of the plants and sea life was spectacular. Thanks Katie you are brilliant. "
  • "The snorkel safari was brilliant a great experience for the whole family. We had no idea there was so much to discover in the water around mount’s bay… so many sea creatures and beautiful colours you felt like you were discovering a secret world. Katie is a fantastic guide she is so knowledgeable and enthusiastic we learnt so much from her. We cannot wait to book again Thanks katie "
