The oceans and seas are incredible things of beauty, with a fascinating mix of underwater gardens and marine life. Of particular importance are the stunning coral reefs, which act as a protection mechanism to coastlines and a home to an array of ecosystems. Many of them are, unfortunately, threatened due to man-made causes and in need of preservation. Here are the most beautiful in the world.

Scuba Diver on Coral Reef, Felidhu Atoll, Maldives

The Maldives are made up of 1,200 islands and 26 atolls; the waters feature a beautiful landscape of corals and vibrant array of marine life. Unfortunately, with the warming of the ocean waters, particularly the El Niño weather event of 1998, a majority of coral suffered from heavy bleaching, dying off; however, over the past few years, there have been encouraging signs of recovery.

The reef comprises over 3,000 individual reef systems, complete with abundant colorful marine life and 400 types of coral. Situated off the coast of Queensland, the reef also features hundreds of islands, many of which have pristine beaches that locals and tourists alike flock to every year. One of the Seven Natural Wonders of World, the Great Barrier Reef is also a UNESCO World Heritage Site.

Located in the South Pacific off the northeast coast of Australia, this double-barrier reef is home to a variety of marine life, many of which are still in the process of being discovered and classified, with the Green turtle and 1,000 fish species already documented. As with most of the stunning habitats, this one is constantly under threat due to man-made causes.

Approximately 1,200 miles long, this reef, which is over 5,000 years old, is home to 300 hard coral species and about 1,200 fish, of which 10 percent are found only in this area. One thing to note about this coral reef is that it is strong, able to withstand a variety of elements including extreme temperature changes.

Located between the second and third largest islands of Fiji, Vanua Levu and Taveuni, Rainbow Reef is the perfect name for this locale, as it features a kaleidoscope of vibrant colors under the water, provided by the hard and soft corals and marine life that call the area home. Indeed, there are 230 hard and soft corals and close to 1,200 fish species, creating a feast for the eyes. With the fantastical beauty, it’s no wonder that this is one of the top diving destinations in the world.

The waters of the Raja Ampat Islands have 450 species of reef-building coral, making it an area with the largest coral reef biodiversity based on its size. When scientists discovered this fact, they put a plan into motion to protect this underwater habitat, as so many reefs around the world are at risk. Located in the heart of the Coral Triangle, an area with 75 percent of all identifiable coral species, the area also has an impressive 1,427 species of fish. With the abundance of biodiversity, it should come as no surprise that Raja Ampat is a favored spot among divers. Fancy a trip to Indonesia yourself? Our 12-day epic adventure to Bali includes snorkelling with sea turtles and seeing underwater statues off Gili Trawangan.

Palancar Reef – Cozumel, Mexico

Divers return again and again to this beautiful hidden gem off the coast of the island Cozumel in Mexico. While it may not be as large as other reefs, it is just as beautiful with its multicolored (think bright pinks, greens, oranges, and yellows) marine flora and fauna. The Palancar Reef is part of a bigger reef system, the Mesoamerican reef system, the second-largest on Earth. The dazzling array of coral serves as homes for seahorses, butterfly fish, sea fans, squirrel fish, parrot fish, and many others.

Great Chagos Archipelago – Indian Ocean

Natural Feature

Located in the middle of the Indian Ocean, the Great Chagos Archipelago comprises 55 islands, and the Great Chagos Bank happens to be the largest coral atoll in the world and also the least polluted and the most protected. Half of the world’s coral is located here, with endemic varieties such as the Ctenella chagius, coral that resembles a brain. Add to that the rich fish population, along with turtles, dolphins, whales, and more. In order to keep the water as pristine as possible, scientists conducting research don’t even wear sunscreen.

Wakatobi Islands – Indonesia

A stunner located in the Coral Triangle, the Wakatobi National Park is 1.39 million hectares, and its blue-green water is home to 750 coral reef species out of the world’s 850, making it a spectacular place to explore. A tentative World Heritage Site, this underwater gem is located off the southeast portion of Sulawesi, Indonesia. Adding to the already impressive scene is the diverse fish presence; indeed, the collection of fish equals 942 species.

Lord Howe Island is a gorgeous island located in the Pacific Ocean. There is much beauty above the sea, but once you dive into the crystal-clear blue waters, there might be even more allure beneath. A marine park and UNESCO World Heritage Site, its marine biodiversity is unique with over 90 coral species along with 500 different species of fish. It’s possible to get close to dolphins, humpback whales, and even sharks (the harmless ones, of course). It is a true paradise.

Belize Barrier Reef – Belize

Another UNESCO World Heritage Site, the entire Belize Barrier Reef Reserve System was inscribed in 1996. It has the largest barrier reef in the northern hemisphere, plus several other highlights like coastal lagoons and mangrove forests. The reef itself contains 106 hard and soft coral species plus 500 species of fish, only about ten percent of what scientists hope to find. However, due to man-made or natural causes, it’s not for certain which, over 40 percent of the coral reefs are damaged, making protection efforts that much more important. You’ll have the opportunity to snorkel the Belize Barrier Reef on our five-day Mini Trip to Belize – which also includes a ride down the Monkey River and a trek through the rainforest to spot wildlife.

Underneath deep blue waters are a smashing array of corals in blues and pinks along with marine life such as trigger fish and sea turtles. Currently on UNESCO’s tentative list for World Heritage Site status, Apo Reef also has National Park status in order to protect this treasure from any undo harm.
