"Fantastic!"
How I did it
So, I as on a holiday in New Zealand - and swimming with wild dolphins was highest on my agenda of things to do there. After a bit of research I found company which organised swimming trips with wild dolphins - all you have to do is sign up.
The dolphins were completely wild and I was quite disappointed that we weren't allowed to touch them, but seeing them swim past you as in the sea was a dream come true.
I would recommend this experience to anyone and everyone - it is one of the best things I have experienced.

Just do it - I am sure you will never regret it!
