I have been on wildlife cruises, I have been swimming in open water, I have done shark cage diving, and I have seen dolphins... I thought thise would be in the realm of all the other experiences, and I was completely wrong! This was easily one of the top ten experiences of my life and I highly recommend this to anyone who can swim. I came all the way from Christchurch to Akaroa for this experience, with doubts in my mind and not knowing what to expect. It was a cold day (low 60s F with wind and off/on rain) and I wasn't thrilled about the weather. I called the company that morning and they assured me that the cruise was still running and they also told me that because the water was choppy, they were only letting experienced swimmers out. I arrived at the shop 20 minutes before the cruise (you have to check in at least 15 minutes before departure) and was given a form to sign and once again asked about my open sea swimming experience and whether or not I got motion sickness. I do get motion sickness, but I took an extra dose of dramamine and took some hard candies with me to help with that. We were then shown into the other room and sized for wetsuits and booties. These were 5ml wetsuits and we were instructed to only wear our bathing suits (togs) beneath them. Then we were sized for booties and given masks, the masks were optional but everything else was mandatory. We were split into our groups and sent off on the small vessels. Immediately, Bo and Daz (sorry if I spelled these wrong!) were ready with the jokes. They told us about the Hector dolphins that we would see as well as how to interact with them and conservation efforts. They drove quickly through the water and we bounced off the waves, it was exhilarating! We pulled up next to a wildlife cruise that had spotted some dolphins and parked there waiting to see if the dolphins were interested in us. And lucky us, they were! The dolphins stuck around and we got off the boat via ladder and entered the water. I was nervous about the cold water, but the 5ml wetsuits were no joke! I was very warm. Soon after, the dolphins started swimming with us! They circled us and jumped and rode the waves. It was a breathtaking experience. The guides said there were maybe 8 dolphins that stayed with us for maybe 1-2 hours but it felt like 30 dolphins and 12 hours. After the dolphins got bored and left us, it was time for us to head back anyway. Bo and Daz pulled up their "ocean uber" to us and we re-entered the boat. We started feeling cold out of the water, and then they surprised us again with a hot water hose that they used to pour warm water down our wetsuits. It felt amazing. We pulled up to calmer waters where they showed us Cathedral Cave and Elephant rock and we shared hot chocolate and ginger cookies. We sped back to beat the other boat so that we could get to the hot showers first. It was truly an experience I will never forget and you would be making a huge mistake leaving New Zealand without doing it.
