There are many coral reefs along the An Thoi Archipelago however most tour agencies will not mention them because they have already established a fixed snorkeling route. If you want to snorkel the best spots and save time get our snorkeling guide.
The coral reefs here are not comparable to those that are typically seen in Indonesia, Philippines, Malaysia, and other parts of the world. If you are a well traveled snorkeler and join an organized snorkeling tour, you may be disappointed to see a lot of the reef being dead. The water here is nutrient rich causing algae to blossom and consuming a lot of oxygen, which results in the delicate corals being crowded out.
Snorkeling tours include a lunch however if you want to try Sea Urchin, then you have to pay an additional fee.
Snorkeling An Thoi Islands
Although it is not part of the An Thoi Islands, some tour operators mislead tourists and take them to Ong Doi Cape for a quick snorkeling excursion and tell them they are visiting the archipelago. Ong Doi Cape (Mui Ong Doi) is located at the very southern tip of Phu Quoc Island. This area has historical significance as the Emperor Gia Long’s boat got stuck in the corals found here while he was fleeing the Tay Son army and a local islander rescued him. The coral reef here is not as spectacular as those found elsewhere on Phu Quoc which is why we highly recommend our snorkeling guide.
