We had the most amazing day out with the kids. We saw so many sea turtles, calm and cool looking leopard sharks and even a manta ray. I had no idea we had such an amazing variety of sea creatures this close to the coast!!! Rudi and his team were awesome and we felt safe and well looked after throughout the whole journey. Highly recommend!
