Hon Mong Tay is a beautiful island in the An Thoi Archipelago. It has an abundance of giant hard corals and rock formations covered in soft corals and anemones offering shelter to a large variety of fish and invertebrates. We didn't find too much single use plastic such as cups, straws and packaging on the dive site, probably due to it's remote location, but the amount of line and nets that we brought up shows that this marine protected area is still in need of better enforcement and regulation. Hopefully, as the diving continues to grow in popularity, so too does the protection that this area deserves.
