While many of us dream of visiting the Grand Canyon, exploring the Great Barrier Reef or seeing the Northern Lights, there are some amazing sights that’ll sadly never be able to grace our wish lists. From sea arches that were torn down by crashing waves to glaciers that disappeared due to climate change, discover the stunning natural wonders that are now gone forever.

This gorgeous painting, created by artist Charles Blomfield in 1882, looks like the stuff of fantasy. But the rosy-hued pools it depicts were once entirely real. Thought to have been situated on the shores of Lake Rotomahana, in the north of New Zealand’s North Island, the Pink and White Terraces were formed by boiling geysers which sent geothermal water spewing down the lake’s shore. As its water cooled, the distinctive layered pools were formed, gaining their pink colour from the presence of sulphides.

Yet the natural attraction, which was once considered the eighth wonder of the world, was engulfed by the eruption of Mount Tarawera in 1886. The spewing volcano made Lake Rotomahana expand by more than 20 times in size, burying the terraces 200 feet (60m) underwater. New Zealand research body GNS Science released a detailed map showing the likely location of the former natural wonder, and underwater cameras have discovered parts of the terraces remain submerged in the lake.

Once upon a time the Hetch Hetchy Valley’s beauty was compared with that of the nearby Yosemite Valley. The steep-sided, U-shaped valley was carved out over millennia by rivers and glaciers eroding the granite rock of the Sierra Nevada mountains. It owes its name to the Miwok word 'hetchetci', used to describe the seeds from grasses which were once abundant on the valley floor – along with plentiful trees and plants, as early photographs show. It was also home to a number of Indigenous groups including the Miwok people.

Nowadays though, the valley floor is buried under 430 feet (131m) of deep water. In 1913, Congress approved plans to turn the valley into a reservoir which would supply water and hydroelectric power to San Francisco. Despite backlash from environmentalists, the valley was flooded and the O’Shaughnessy Dam was completed in 1938.

Photographed here in 1918, the Wawona Tree was a giant, ancient sequoia tree in Yosemite National Park. The tunnel was cut through it in 1881, prompting visitors to take pictures of themselves walking or driving through it – several other trees in US national parks had tunnels cut through them in the 19th century, with the idea being that they’d attract tourists.

However, hacking into a living tree causes substantial damage to it. So when the harsh winter of 1968-1969 hit, bringing heavy winds, intense snow and rainfall, the Wawona Tree had already been structurally weakened and it toppled to the ground in February 1969. Before the fall, it had reached the grand old age of 2,100 years and measured a towering 234 feet (71.3m) tall.

Moving on from ancient trees to ultra-isolated ones, the Tree of Tenere in the middle of the Sahara Desert was once nicknamed the loneliest tree on Earth. Shown here in 1961, the acacia sat some 250 miles (402km) away from the nearest tree and dated back to a time when Niger had been much greener and wetter. It had become something of a landmark for those travelling through the region.

Tragedy struck in 1973 when the tree, so famous it appeared on maps, was hit by a truck and fell to the ground. The culprit was never named but many suggested it had been a drunk driver. By way of a memorial, a statue has been constructed in its place, with the original tree currently held in the Niger National Museum.

Named after the British bridge which it closely resembled in shape, the London Bridge rock formation once graced the southwestern coast of Victoria along Australia’s Great Ocean Road. But although it took hundreds of years of erosion for the arch to be formed, it fell down overnight…

Prompting plenty of cries of “London Bridge is falling down”, the iconic structure collapsed on the evening of 15 March 1990. Two tourists had walked over it just minutes beforehand – fortunately, no one was hurt when it fell down. Today, the piece of rock that once connected it to the mainland has fallen away, but a smaller arch still stands, as you can see here.

It was often thought that Jeffrey Pine was the most photographed tree in the world. With its incredible wind-hewn shape, the tree, which was estimated to be around 400 years old, certainly cast a striking silhouette against the backdrop of Yosemite National Park. It was made famous by a snap from Ansel Adams in 1940 (seen here in 1968) and since then has attracted photographers and nature lovers from all over the world.

Sadly, the gorgeous tree was eventually killed off by the harsh weather that originally gave it its distinctive shape. It died during a drought in 1977 but stood for a further quarter century, before a series of storms in August 2003 led it to crash to the ground. However, Jeffrey Pine has been left in its original spot so that visitors can still see and photograph it today.

Let’s clear something up: there were never actually Twelve Apostles. These distinctive sea stacks along the coast of Victoria, Australia gained the moniker in the 1960s when they were named after the 12 apostles in the Bible, although at the time there were only nine of them. They were carved away from the cliff by a process of erosion which began some 10-20 million years ago, initially creating caves in the rock face which became arches, then sea stacks. 

Yet the crashing waves which tore them away from the cliff in the first place will also, ultimately, be responsible for their collapse. In 2005, one of the stacks crumbled down, then another fell in 2009. Today, there are seven in total, although one is located further out to sea and isn’t as easily visible from the main viewpoint. 

Located just off the coast of Agaete on the island of Gran Canaria, El Dedo de Dios – or “God’s finger” in English – was once a spindly basalt pillar, named for its finger-like shape. The gravity-defying piece of rock served as an inspiration to artists and a landmark in the local area.

Yet the miraculously tall and thin rock formation couldn’t stay standing forever. In 2005, Tropical Storm Delta hit the Canary Islands and sent the upper part of the pillar crashing into the sea, while only the stubby base remained. Today, the part that remains has been renamed Roque Partido, meaning broken rock.

Utah’s Arches National Park contains an impressive 2,000-plus sandstone arches, as well as spires, balancing rocks and other stunning formations. Wall Arch, which was the park’s 12th largest at 71 feet (22m) wide and 33.5 feet (10m) tall, was especially popular with visitors due to its proximity to walking trails.

Sadly, disaster struck on the night of 4 August 2008. Over the course of hundreds of years, erosion had eaten away the calcium which essentially holds the rock together, leaving it weaker and more vulnerable to falling down. It’s not known what the immediate cause for the collapse was that night, but national park representatives visited the site a few days later and noticed stress fractures in the rock that would’ve led it to fall.

It’s thought that before it disappeared, Chacaltaya Glacier had been around for 18,000 years. The glacier, located near La Paz, was once home to a popular ski resort – which at a dizzying 17,785 feet (5,421m) of altitude was the highest in the world. Scientists first began measuring the glacier in the 1990s and predicted it would disappear in 2015.

Yet, accelerated by climate change, the glacier had vanished almost completely by 2009. It’s estimated that the region’s temperature had risen by 0.5°C (0.9°F) between 1976 and 2006, which made the glacier melt away faster than expected. Today, all that’s left is an eerie abandoned ski resort which is visited by a handful of tourists each year.

Around a century ago, Okjokull glacier in western Iceland covered six square miles (16sq km) and was more than 160 feet (49m) thick. Situated at the top of the Ok volcano, the glacier was thought to have existed for around 700 years and had been monitored closely by the Icelandic Meteorological Office for several decades. According to glaciologist Oddur Sigurdsson, snow had been melting on it faster than it could build up.

In 2014, the glacier was officially declared dead. Which may sound like a strange description for a lump of ice. But glaciers usually work by accumulating snow, which creates enough pressure for them to move, and since Okjokull had reduced to a thickness that meant it could no longer move, it was pronounced dead. A plaque was installed to commemorate it and climate change activists gathered in 2019 to hold a funeral for the glacier, which was the first in Iceland to lose its status as a glacier.

These are Iceland's most incredible sights

Situated in the heart of the Andes at some 12,139 feet (3,700m) elevation, Lake Poopo was once Bolivia’s second-largest lake. A mere few decades ago, it would reach a size of 1,158 square miles (3,000sq km) during the rainy season. It was a biodiverse habitat for around 200 animal species, including fish, birds and a large number of flamingos, plus it served as an important source of water and fish for indigenous Urus-Muratos people.

Yet the once-thriving lake has become a victim of the climate crisis. At the end of 2015, the lake dried up completely following droughts caused by the El Nino phenomenon, leaving a salt desert behind. Although the lake has rebounded before, it remains dry today and scientists have voiced concerns that it may never return. As well as climate change, the lake’s disappearance was sped up by the diversion of water from its tributaries, used for farming and mining. 

Named for its duckbill-like shape, this recognisable rock had graced the shoreline of Cape Kiwanda, Oregon since the early 1900s. The seven-by-10-foot (2.1 by 3m) formation was carved into its trademark form over the course of thousands of years, and had become a well-loved landmark popular with travellers, locals and photographers alike.

So in August 2016, when reports emerged that the rock had collapsed, many people mourned the loss. Sadness quickly turned to outrage, however, when they learned of how it fell. That September, video footage emerged showing a group of vandals intentionally pushing the rock until it collapsed. The man who had filmed the video had approached the vandals, one of whom had said they’d toppled it because he’d injured himself on it, calling it a “safety hazard”. An outpouring of messages paying homage to the rock flooded social media, while locals voiced their anger about the vandalism.

Few coastlines on Earth quite match the beauty of Morocco’s Atlantic Coast, where the stunning Legzira Beach is located. The weather-beaten rocky beach has long been known for its two recognisable rock arches, which draw in travellers and photographers from all over the world. It’s said that sunset is the best time to visit, when the coastline turns a vibrant red.

In late 2016, one of the two rock formations fell, leaving nothing but a pile of rubble on the shore. The exact cause of the collapse is unknown, although there had been a large crack in it since March that year, and it’s thought that crashing waves probably had a part to play. Time is ticking for the second arch too, as the sea continues to weaken it.

Perhaps one of the most photographed sea arches on the planet is Malta’s Azure Window. Situated on the island of Gozo – the filming location for Game of Thrones and several popular movies – the limestone bridge was one of the most popular attractions in Malta. 

Sadly, heavy storms caused the arch to come crashing down in March 2017. Although it was expected to collapse eventually due to erosion, its demise had come sooner than expected, accelerated by the harsh weather conditions. Then-prime minister Joseph Muscat described the landmark’s downfall as “heartbreaking”.

At the end of the 19th century, Antarctica’s Larsen Ice Shelf had an area of 33,000 square miles (86,000sq km). Yet climate change, which has caused significant rises in air temperature above Antarctica, has led it to shrink at a worrying rate. In 1995, the first section of the shelf – known as Larsen A – became detached.

This was followed by the disintegration of a further section, Larsen B, in early 2002. After these two events just two-fifths of the original ice shelf remained. But the alarm bells were sounded once again in 2017, when a large iceberg broke away from Larsen C in one large chunk, exposing the marine life beneath it to light for the first time in 120,000 years. However, scientists from the British Antarctic Survey say that the Larsen C ice shelf can be protected if actions are taken to curb emissions and climate change.

The beautiful Sycamore Gap tree sprouted from a dip in the ancient Roman Hadrian's Wall in northern England close to Hexham, and has graced the landscape for more than 300 years, visited by millions of people and becoming one of the UK's most photographed trees.

Sadly, national park authorities found the tree had been cut down using a chainsaw in a deliberate act of vandalism in September 2023, with just the stump left at the spot. In a modern twist, the tree's twigs and seeds have been used to nurture new saplings in a secret location, so that the tree may be regrown if no new shoots emerge from its original stump.

Hillary Step, named after the first person to summit Everest – British explorer Sir Edmund Hillary – was a famous rocky outcrop on the south face near the top of Mount Everest and the last major obstacle facing climbers before they reached the peak. Seen here in 2010, mountaineers were forced to traverse the sheer 39-foot (12m) block on their way up and down the world's highest mountain.

But a massive earthquake in 2015 shook the boulders loose, reducing the Hillary Step to rubble, and smoothing the way to the top, with climbers reporting that the south face ascent had been made easier. The resulting sloped area is now referred to as the Hillary Staircase, pictured here in the distance as climbers attempt to reach the summit in 2021.

Central Asia's Aral Sea was once the fourth largest salt lake in the world covering a vast area of 63,000 square kilometres between Kazakhstan and Uzbekistan, with fish-filled delta systems fed by two rivers. It was named 'Aral', meaning island in Kazakh, after the more than a thousand islands that dotted the shallow inland sea. But water levels started to drop in the late 20th century, leading to the lake dramatically shrinking (shown here in a NASA satellite image).

Locals had started to notice the shore was receding in the 1960s after two rivers feeding the lake were diverted, and by the late 1990s its total area had decreased by more than 60%. In the 2010s, satellite images confirmed the fragmented lake had all but dried up, leaving behind a desert wasteland and ship's graveyard (pictured) in its wake.

Named after Charles Darwin, the biologist who developed his theory of evolution on the Galapagos islands, Darwin’s Arch was a stunning rock bridge located just off its namesake island. As well as being gorgeous to look at, the landmark is a top scuba diving spot and its surrounding waters are filled with dolphins, sea turtles, rays and fish.

Disaster struck on 17 May 2021, when Ecuador’s Environment Ministry reported that the rock formation had fallen. That morning, tourists on a boat had witnessed the moment the top of the arch fell into the ocean, leaving behind two pillars of rock, now renamed Darwin's Towers. The Environment Ministry cited natural erosion as the cause of its fall.
