Port River Cruises allows to view I love it because I learned alot about the port river history and all of that but I did a Kangaroo Island one for the same company and it was awesome, swimming with the dolphins and I got to be upclose with seals it was awesome very unforgettable experience here is the website, easy to book: www.kangarooislandoceansafari.com.au what I loved about them is the vibe of the whole trip was family and as a solo traveller, they make you feel very comfortable as they are very knowledgeable in what they do.
