There are a number of different species of aquatic plants and animals that live in or around waterfalls or fast-moving streams. Many rivers also have unique geological features that make them popular tourist destinations.
Underwater rivers look very different than the ones we’re used to seeing above ground. They might be small and narrow, but they are no less beautiful or exciting to explore. Here is our list of the Top 5 Underwater Rivers You’ll Want to Visit…
List Of Top 5 Underwater Rivers
The Blue Hole
The Blue Hole is an underwater sinkhole near the island of Cayman Brac in the Caribbean Sea. With a diameter of about 100 meters (330 ft), it is one of the world’s largest blue holes. It is said that the name “blue hole” became popular after a scuba diver noticed that the water above the hole is much lighter in color compared to the rest of the sea.
The floor of the Blue Hole is teeming with marine life, including several species of fish endemic to the area. The Blue Hole is also a popular destination for scuba divers. There is a large coral reef at the bottom of the hole, which attracts a variety of fish and other marine life.
St. Augustine Blue Springs
Blue Springs State Park is located about an hour’s drive northeast of Orlando on the border between Orange and Seminole counties. The park is famous for its underwater blue springs, which flow right through the park. This freshwater spring system has been flowing for thousands of years, and it is one of the largest in Florida. The park is also home to a wide range of wildlife, including alligators, turtles, and various aquatic birds.
The park’s centerpiece is the underwater river (Blue Springs). The two springs, one on each side of the St. Johns River, flow at a rate of about 1,000,000 gallons per day and are the second largest springs on the St. Johns River. The water temperature ranges from 68 to 72 degrees Fahrenheit and is about 15 feet deep. The springs are fed by a large underground aquifer and are the only underwater springs in Florida that are accessible for public recreation.
Caloura River
The Caloura River is one of the most famous underwater rivers in Brazil. Caloura is an important river for both tourism and research. It flows into the Atlantic Ocean near the city of Natal, Rio Grande do Norte. Over the past few years, researchers have been studying the river to learn more about marine biodiversity.
The Caloura has several species of marine life that are endemic to the river. The river is also important for the tourism industry in the area.

Varadouro River
The Varadouro River is a small river located in an area called the “Canyon of the Sirens” near the city of Nazare in Portugal. The area has a long history of shipwrecks, and the river, which is only about three feet (1 meter) deep, was created by the wreckage from these ships.
The underwater river is about 1 km (0.6 miles) long and gets its name from the “red rocks” that line the canyon. The Varadouro is a popular tourist destination and is often referred to as the “Underwater Canyon.” Visitors can walk along an underwater path and see a variety of marine life, including brightly colored fish and sea anemones.
