The tropical coral reefs are the most beautiful ecosystem in the world.
There, I said it.
The biggest reef in the world is of course the Great Barrier Reef, off eastern Australia. Along the edge of this reef are the beautiful Ribbon Reefs. There is also Lizard Island, On the west coast of Australia there are other reefs, including Montgomery Reef in the north east, and further south is Ningaloo Reef.
The south west Pacific includes the Solomon Islands, my favourite country for snorkelling. One of the best sites in this area is at Maravagi Resort, on Mangalonga Island. Other areas in the Solomon Islands include: Uepi Resort, Marovo Lagoon and Arnavon (Arnarvon) Islands.
At a similar latitude is the relatively unspoilt island of New Guinea. This includes the most diverse coral reefs in the world, at Rajah Ampat.
Heading north there are the remote islands of Micronesia, including Palau. Then there is the diverse and many islands of the Philippines, including Panagsama. Even further north is the extent of tropical coral reefs, Japan. Here, snorkelling is easy at Miyako Island.
