There aren’t a lot of places suitable for snorkelling near Kempsey. Under the footbridge across South West Rocks Creek from Buchanan Dr (also known as Back Creek Bridge) is one spot that is great for someone new to snorkelling though. See the map below the video for where this was taken. When the tide is in it is shallow enough to easily touch the ground but there are still quite a few fish around, many of which are quite interested in people.
