The UK is home to many spectacular places. There are ancient stone circles, long stretches of sandy beaches, and high mountain peaks that attract visitors year after year. Stonehenge, the White Cliffs of Dover, the Peak District and Snowdonia are just some of the natural landmarks that continue to impress tourists from the UK and abroad.
But one location in Northern Ireland is being called the "8th Wonder of the World" by those who've seen it in person, and many say it's like nothing else in the country. The Giant's Causeway sits a few miles from the town of Bushmills on the north coast. It's made up of around 40,000 interlocking stone columns that stretch into the sea.
Most of them are hexagonal and appear almost man-made, but they were actually formed by volcanic eruptions around 50 million years ago.
Travel experts at City Tours Belfast said: "It's a place that looks more like a film set than a real-life location.
"And although it's not officially listed alongside the likes of the Taj Mahal or Machu Picchu, many locals, and visitors, consider it the '8th Wonder of the World'."
There's also a legend behind the landmark. According to Irish mythology, the rocks were built by a giant named Fionn mac Cumhaill so he could cross the sea to Scotland and fight a rival.
The site became a UNESCO World Heritage Site in 1986 and welcomes over a million visitors every year.
There's a visitor centre with exhibitions, a café, and a shuttle bus to take people down to the rocks. Walkers can also take several clifftop paths with views of the coast.
One visitor wrote on Google: "The Giant's Causeway is truly amazing. When you see the cool stone columns, it feels like magic.
"They are so big and special, it's hard to believe nature made them. I really think it should be called the 8th Wonder of the World."
Another said: "The land looks so cool and different, with all the perfect stone columns going into the sea.
"The walk by the coast has awesome views. It totally feels like it should be the 8th Wonder of the World. Don't miss it."

A third added: "The rough coast, the waves hitting the rocks, and the very unique shapes make this a trip you won't forget."
Some visitors recommended taking the red trail if you're comfortable with heights. One said: "The view is simply amazing and it doesn't require a particularly strong effort."
Others advised using the shuttle bus back up the hill if travelling with young children or anyone with mobility issues.
The Giant's Causeway is about 90 minutes by car from Belfast and is also easy to reach from towns like Coleraine, Portrush and Bushmills.
Many also choose to take the Causeway Coastal Route, which has been described as one of the most scenic drives in the UK.
Those who visit often say it's one of the most impressive natural places in the country, and for some, the best of them all.
