Coasteering was a completely new activity to me, so I didn't know what to expect. I am a very poor swimmer and I am afraid of heights, but the tour guides were very kind and encouraging and made me feel very safe the entire time. By the end of the tour, I had done some of the medium size jumps. Highlight of the day was a beautiful cave towards the end of the tour that we climbed and swam under. I loved it!
