Honolua Bay
United States of America (USA)
During the winter months Honolua Bay gets some of the big waves that make Maui famous, the waves that surfers love also bring nutrient dense water into the reef keeping it healthy. In the summer months, and on special winter occasions, Honolua Bay is a must. The coral formations are exceptional, you’re bound to see some large turtles, and mantas are even spotted in certain seasons.
Mike's Maze
Sint Maarten
Part of the Man of War Shoal Marine Protected Area. It starts at approximately 40 feet (12 m) and boasts healthy coral formations and numerous maze-like swim throughs, passageways wind around coral heads, through arches and over bridges. This location is where the Nature Foundation conducted one of its coral reef restoration projects. Common critters: Many of the 60 TWA fish species! French Angelfish, schooling Chubs, Spiny Lobster, & Foureye Butterflyfish, Elkhorn Coral formations, Special guests: Spotted Eagle Rays, Squid, Caribbean Reef Sharks, Nurse Sharks, Sexy Shrimp in anemones, staghorn coral formations
Nemo Reef
India
Nice and clear water with an abundance of marine life as well as corals. It has a flat sandy bottom with a gradual slope starting right from the shore.
Suriya's Hideout
India
Suriya’s Hideout is an artificial reef dive site consisting of concrete block structures intentionally deployed to promote marine habitat development. Over time, the site has evolved into a thriving ecosystem, attracting a variety of reef fish and juvenile species seeking shelter within the block formations. The layout creates swim-through style spaces and protected areas, making it an engaging dive for underwater exploration and marine life observation. This site is suitable for both beginner and advanced divers depending on current conditions
Tulamben
Indonesia
The wreck lies in shallow water and is considered appropriate for divers of all certification levels. The ship rests in 30 metres of water, is roughly 25 metres from shore and can be reached with a short swim from the beach. The highest point of the wreck tops out about 5 metres from the surface. The ship was torpedoed by the Japanese off the nearby Island of Lombok and the ship was towed to the beach at Tulamben for salvage operations. The 1963 eruption of Mt. Agung, which devastated much of the eastern side of Bali, drove the ship into the water just off shore, where it became encrusted with coral and a home to other sea life.
Twins
Thailand
Twins is located to the south of Koh Nangyuan. A very popular dive site has plenty to offer for everyone. The 3 main pinnacles run from east to west along the coastline of Koh Nangyuan. There are 2 large groups of boulders with plenty of coral growing on them and a collection of deeper rocks further west. Twins is almost the perfect dive site for scuba diver training. The depth ranges from 6m on the eastern side to 18m at the deeper pinnacle on the west side of the dive site. Marine life can thrive at this dive site due to its sheltered location. The island of Koh Nangyuan to the north provides shelter from wind and waves even in monsoon time. Expect to see plenty of tropical reef fish at this dive site. Common sightings include the bright yellow butterflyfish, blue-ringed angelfish and longfin bannerfish. There is a very good chance you can see white eyed moray eels hiding out in between the coral. The top of the boulder corals is often covered with colourful Christmas tree worms.
White Rock
Thailand
The range of life found here is huge and there is something to please every diver. Turtles come here to munch away on soft corals, casting a lazy, half-interested eye at divers. Koh Tao's infamous Titan Triggerfish prowl this dive site too, and some of the largest specimens hang out here. White Rock attracts many hunters: Great Barracuda and Trevally excite the fish making them dart for cover in the plentiful hard corals; Banded Sea Snakes wind their way through the corals searching for their prey. Blue-Ringed and Six-Banded Angelfish swim around in their buddy teams passing Beaked Coralfish, Bannerfish and Pig-Faced Butterflyfish. Look under ledges and outcroppings and you are bound to find a White-Eyed Moray Eel or a Blue-Spotted Ray awaiting nightfall. Under the South buoyline, a large shoal of Yellowtail Barracuda spend their days following divers. Even though White Rock is close to Koh Tao, in season Whalesharks are regularly seen here.
Confucius Rock孔子岩
Taiwan
[Confucius Rock] An unknown scenic spot in the hot spring village, facing the sea there is a sea-eroded upright reef (looks like Master Kong?), the actual location of the dive site is about 2-300 meters on the right side of the road. Walk on the trail at the end of the guardrail. It takes about 5 minutes to reach the intertidal zone and then connect via the lagoon. It is recommended that it is easier to go when the tide is high for the first time. After going out of the lagoon for a while, you will see a small cave below. Then you can start to dive, and then find a not too narrow entrance on the left. If you have no experience in diving in a closed space, please assess your own risk before entering ( You can also choose to continue from the top of the reef through the following paragraph (that is, not to take the route of the closed cave). The target direction is the outcropping reef in the distance. After swimming through a short section of intertidal zone, a large rift valley is ushered in. At this time, you can start to dive. The depth of the rift valley on the right is about 10 meters, and the coral composition is very rich. The terrain is also very special, because although the area is quite large, although it is not the main excitement of the dive site, it is also worth going around. Turning to the front left, there will be a reef close to the water surface full of clownfish, and then you can explore along the cliff to the right. From here, the sand and the cliff can be easily navigated, about 17 meters away. There is a light-transmitting tunnel on the right side of the sand. This is a place where friends who are just starting to dive can practice well, and then go deep along the sand to about 25 meters and pass through a few small reefs in the sand. After crossing them, you will see a large reef full of various soft corals, on which there are many kinds of small fish such as golden seabass, blue damselfish and so on. It takes about 3-5 minutes to slowly appreciate and circle the complete reef. At this time, you should pay attention to the computer watch prompts. You can watch in the water layer and don't have to be at the bottom to avoid decompression. On the return journey, you can choose to swim back on the other side of the sand, and then use the rift valley as the identification or the tree on the left side of the black house on the shore as the water outlet. Be aware that there may be white waves on both sides, and be careful of falling on the shallow reef section. Creatures have the opportunity to see damselfish, snapper, clownfish, sea turtle, squid, sea slug, parrotfish, hornfish, and scorpionfish.

Stetson Bank NMS
United States of America (USA)
Stetson Bank is located 48 km northwest of the Flower Gardens. It was added to the Flower Garden Banks National Marine Sanctuary (FGBNMS) in October 1996. The sanctuary serves as a biological reservoir of Caribbean species in the northern Gulf of Mexico. Temperatures at Stetson Bank are a few degrees cooler in winter than in the Flower Gardens. The bank supports an extraordinary fish community. Community Structure: The cooler winter temperature at Stetson Bank relative to the Flower Gardens prevents coral reefs to thrive. Instead, scattered coral colonies with a dominant sponge community occur. Geological Characterization: Stetson Bank is a surface expression of salt diapirs capped by uplifted layers of claystone and sandstone, which have eroded at unequal rates to create a strange "moonscape" appearance. It is among the smallest of the mid-shelf banks in the northern Gulf of Mexico. It is a pelagic zone feature with clay/siltstone bedrock.
