The world is filled with beautiful and fascinating places - but not all of them are on land.
In fact, there are some pretty incredible underwater attractions around the world, and you don't need to be a seasoned diver to explore them.
We're talking restaurants submerged underwater with glass roofs so you eat amidst the marine life, incredible lakes that transform into mountains during dry seasons, and even underwater waterfalls.
For those who do want to enjoy a spot of diving or snorkeling, you can find weird and wonderful dive sites ranging from ancient cities to sunken Boeing aircraft.
Prepare for a dose of wanderlust as we take a look at the world's coolest underwater attractions...
1. Cancun Underwater Museum of Art, Mexico
Usually art museums involve large galleries you wander through - but this one is completely submerged under water, so you'll need to dive down and swim along.
There are over 500 life-size sculptures to discover, all of which have been built to promote coral life.
You can explore through snorkeling and diving, but if you don't want to get in the water there are also glass bottom boat tours that offer a glimpse of the artwork.
2. Shicheng, China
Dubbed the 'Atlantis of the East', Shicheng is an ancient city which sits about 26-40m below the surface.
Once a thriving city, the valley in which it is located was flooded over 1300 years ago. It's a popular diving site, predominantly because the water has protected the stone architecture from wind and sun erosion.
Nowadays you can take guided tours to get close to the ruins, although you will need to be a seasoned diver.
3. Dive Bahrain
Bahrain's new underwater museum opened in 2019 and features a sunken Boeing 747 for divers to explore.
The 70m-long airplane was submerged underwater on purpose, as part of the new attraction which will also boast 100,000 sq m of activities and trails for divers, ranging from colourful artificial reefs to underwater sculptures.
One diver shared a video as he explored the site and while it doesn't have much marine life at the moment, it's still pretty impressive.
4. Ithaa Underwater Restaurant, the Maldives
The Conrad Maldives Rangali Island offers up a dining experience unlike any other right in those picture-perfect ocean waters the Maldives are renowned for.
The restaurant sits under the sea and has glass walls and a glass ceiling so diners can take in the views of the marine life that thrives around the shores, as well as the eye-catching coral gardens.
5. Sweepstakes Shipwreck, Canada
Lake Huron in Ontario is where you'll find the shipwreck of Sweepstakes, a schooner which hit a rock near Cove Island. It was towed to the nearby lake where it sank in the shallow water.
Nowadays you can snorkel or dive to get up close to the wreck, while the picture-perfect landscape around the lake is worth a visit alone.
6. Dos Ojos Cenote, Mexico
The 'Two Eyes Cenote' has earned its name thanks to two sinkholes that form the cenote, joined by a 400m-long passageway. It's also one of Mexico's largest underwater cave systems.
There's an impressive amount of light that reaches the waters making them crystal-clear, and therefore a big hit with both snorkel and diving fans.
7. Underwater waterfall, Mauritius
On the island's southwestern coast sits a spectacular underwater waterfall. It's actually the result of sand and silt on the ocean floor forming an illusion that there is a waterfall - but the strong currents mean that this one is best admired from afar.
If you want to witness the natural phenomenon then you won't be getting into the water - the best way to see it is from the air, and there are plenty of seaplane and helicopter tours on offer.
8. Underwater Post Office, Vanuatu
Forget writing a traditional postcard - at the Hideaway Island marine sanctuary, you can head to the underwater post office and send special waterproof messages to your loved ones.
The hotspot is available to both snorkellers and divers, and it makes for quite a quirky photo opp too!
9. The Green Lake, Austria
In the winter, the lake has depths of around 1-2m, and is surrounded by a picturesque park.
However, come summer time, as the surrounding mountain ice melts, the lake fills up and the park is submerged, creating depths of up to 12m. Oh, and thanks to the lush landscape, the waters boast a striking emerald green shade.
10. Underwater Sculpture Park, Grenada
This underwater gallery of sculptures sits in a marine protected area, and while they are striking artwork they double up as artificial reefs, drawing in an impressive array of marine life.
There are heaps of sculptures of life-size people in various activities, from sitting at a desk in front of a typewriter to a circle of children playing a game.
