Amazing experience, captain gorgeous was just as great. He made it a very special trip for mine and my partners weekend get away, he was very communicative, and even took time to take a photo of us on the boat. And recommended stuff for us to do in Cardiff bay, we definitely return again!

You just turn up and get on board, maximum of 11 passengers, but it's only a 20min wait before he returns. Very knowledgable 'Captain' about the local sites as you cruise around the Bay. Very reasonable cost at £6 (£3 for children) Brilliant. Thank you.
