I find it amazing just how much life there is in the sea here. I've put together a video of some of the stuff I've seen snorkelling over the past couple of days. There is so much to see down there.
The video is a bit jerky in places, as unlike scuba diving where you can take your time to steady yourself, with snorkelling, you have to get down quick and are limited to how long you can hold your breath down at 4 metres. Still gives an idea of what it is like.
