Travel: 20 World Wonders to See in a Lifetime

There are two ways to travel. The first consists of ticking boxes on a map, photographing fast, leaving faster. The second, more demanding, asks for time: understanding why a stone was carved in a specific place, what a people says through its architecture, how a valley shapes cuisine and myths. This guide gathers twenty destinations that deserve the second approach, along with practical advice for building an itinerary that goes beyond an Instagram album.

The seven modern wonders

In 2007, a poll organised by the Swiss foundation New 7 Wonders, mobilising one hundred million voters, designated the seven modern wonders. The list holds no official status, but it draws a useful map for anyone trying to understand humanity as a builder.

Petra, the rose city carved into the cliff

Capital of the Nabataean kingdom, rediscovered in 1812 by Swiss explorer Johann Ludwig Burckhardt, Petra hosts the famous facade of the Khazneh, cut directly into the rock during the 1st century. The Jordanian site stretches over more than 60 km², of which less than 20 % has been excavated. To escape the crowds, arrive before 7:30 AM or take the steep trail that leads to the Monastery from behind. Best season: March to May or October to November, when temperatures are bearable.

The Great Wall of China

More than 21,000 cumulative kilometres, built over more than two thousand years. Contrary to legend, it cannot be seen from the Moon. The Mutianyu section, north of Beijing, offers fewer crowds than Badaling and a spectacular view. The wild Jiankou portion, on the other hand, is unrestored: for experienced hikers only.

Christ the Redeemer in Rio

Thirty metres high, seven hundred tonnes of reinforced concrete and soapstone, completed in 1931 after nine years of work. The monument was designed by Brazilian engineer Heitor da Silva Costa and sculpted by Frenchman Paul Landowski. At the summit of Corcovado, 710 metres up, the statue offers a panorama over Guanabara Bay, Sugarloaf Mountain, and the favelas clinging to the hills.

Chichen Itza, the Mayan clock

The pyramid of Kukulkan, also called El Castillo, was built between the 8th and 12th centuries. At the spring and autumn equinoxes, the shadow cast on its staircase draws a serpent descending to the ground. The Maya knew the tropical year with a precision exceeding our Gregorian calendar.

Machu Picchu, the citadel in the clouds

Built around 1450 under the reign of Pachacutec, abandoned less than a century later, rediscovered by American historian Hiram Bingham in 1911. At 2,430 metres of altitude, the Inca city combines agricultural terraces, astronomical temples and royal residences. The Inca Trail, walked over four days, now requires a permit bought several months in advance.

The Roman Colosseum

Eighty thousand spectators attended the games at the Flavian Amphitheatre, inaugurated in 80 AD under Emperor Titus. Its velarium system, an immense canvas sail manoeuvred by sailors of the imperial fleet, shielded the public from the sun. A guided tour including the underground chambers, where wild beasts waited before bursting into the arena, is worth the extra charge.

The Taj Mahal, an anthem of love in marble

Built between 1631 and 1648 by Mughal emperor Shah Jahan in memory of his wife Mumtaz Mahal, who died in childbirth. Twenty thousand workers, inlaid semi-precious stones (lapis lazuli, jasper, jade), perfect symmetry. The lighting shifts the marble from soft pink at dawn to warm gold at sunset. Avoid Fridays, when it closes, and the monsoon in July and August.

UNESCO sites that deserve more attention

Beyond the wonders popularised by guidebooks, certain exceptional places lack the same fame but offer comparable intensity.

Angkor, the sleeping Khmer empire

More than a thousand temples spread across 400 km². Angkor Wat is the largest religious monument in the world: a 200-hectare enclosure. But it is Ta Prohm, strangled by the roots of centuries-old silk-cotton trees, and the Bayon with its 216 stone faces, that truly haunt the memory. Avoid January and February when tour groups flood in; prefer June despite the humidity.

The Galapagos, laboratory of evolution

The Ecuadorian archipelago where Darwin first set foot in 1835. Nineteen volcanic islands, three thousand endemic species, marine iguanas that dive to ten metres, century-old tortoises. Tourism here is strictly regulated: a naturalist guides every group, and visitor numbers are capped. Choose an eight-day cruise rather than a hotel base.

Yellowstone, geology in motion

The first national park in the world, created in 1872. Three million acres above a dormant super-volcano. Old Faithful erupts roughly every 90 minutes, the Grand Prismatic Spring spreads its 110-metre diameter in improbable colours, produced by thermophilic bacteria. Wolves, bison, grizzlies, elk: the wildlife here can be observed like nowhere else on the North American continent.

Bagan, plain of pagodas

In Burma, more than 2,200 Buddhist stupas and temples built between the 11th and 13th centuries dot a plain of 100 km². The sunrise hot-air balloon ride, when balloons sail over the mist above the sanctuaries, remains a memory difficult to replicate elsewhere. The country's political situation calls for careful monitoring before any trip.

New Zealand's Fiordland

On the South Island of New Zealand, the fjords of Milford and Doubtful Sound carve their way through thousand-metre cliffs. Rainfall is colossal (seven metres per year at Milford) which multiplies temporary waterfalls. An overnight cruise in Doubtful Sound, free of light pollution, offers one of the purest starry skies in the southern hemisphere.

Cappadocia and its underground cities

In central Anatolia, erosion has carved fairy chimneys from volcanic tuff. Early Christians dug entire churches with preserved Byzantine frescoes, along with eight-storey underground cities such as Derinkuyu, capable of sheltering twenty thousand people. Hot-air balloon flights at sunrise have become the emblematic image of the region.

Lalibela, the Ethiopian Jerusalem

Eleven monolithic churches carved from basalt rock in the 12th century under the reign of King Gebra Maskal Lalibela. The Church of Saint George, shaped like a Greek cross, is hewn twelve metres deep into the ground. The fervour of Coptic pilgrims dressed in white, during the festivals of Genna or Timkat, offers a striking spiritual experience.

Seven cities that warrant a prolonged stop

Kyoto, the soul of Japan

One thousand seven hundred Buddhist temples, four hundred Shinto shrines, seventeen UNESCO World Heritage properties. Beyond Kinkaku-ji and Fushimi Inari, the Higashiyama district after 6 PM, the dry gardens of Daitoku-ji, the Nishiki market at dawn: Kyoto rewards slowness. Cherry blossoms in April, autumn foliage in November.

Marrakech, ochre and blue

Medina classified by UNESCO, the Majorelle Garden brought back to life by Yves Saint Laurent, the Bahia Palace, Jemaa el-Fna square with its snake charmers and storytellers. Book a riad inside the medina rather than a hotel in the new town: you only understand Marrakech by getting lost in it. Excursions to the Ouzoud waterfalls or the Ourika Valley start from the city.

Reykjavik, gateway to the Arctic

A small capital of 130,000 inhabitants, an ideal base for exploring the Golden Circle, the Reykjanes Peninsula or the southern coast. From September to March, northern lights are possible. The Lutheran architecture of Hallgrimskirkja, the prismatic glass facade of the Harpa Concert Hall, the geothermal pools: the city compensates for its modest size with remarkable cultural density.

Lisbon, seven hills and a river

Portuguese capital marked by the earthquake of 1755, rebuilt according to the plans of the Marquis of Pombal. Tram 28, viewpoints overlooking the Tagus, fado in the alleys of Alfama, pasteis from the century-old bakery in Belem. An hour away by train, Sintra and its multicoloured Pena Palace, or Cascais and its Atlantic beaches.

Buenos Aires, the Paris of South America

The La Boca neighbourhood and its street art, the tango milongas of San Telmo, the Recoleta cemetery where Eva Peron lies, historic bookshops like El Ateneo Grand Splendid (a former theatre converted into a bookstore). Try the empanadas saltenas, the asados, a Malbec from Mendoza.

Cape Town, mountain and ocean

At the foot of Table Mountain (1,086 m), accessible by cable car, the South African city combines Atlantic beaches, Stellenbosch vineyards, and the poignant memory of Robben Island where Mandela was imprisoned for twenty-seven years. The scenic route around the Cape of Good Hope and the penguin colony at Boulders Beach round out the picture.

Hanoi, Vietnamese vibrations

The old quarter of the 36 guilds, Hoan Kiem Lake at the heart of the city, the water puppet theatre carrying a thousand-year-old tradition, hot pho eaten on tiny stools. Halong Bay and its 1,600 karst islands can be reached in three hours by road.

Preparing for a long journey: the essentials

Visas and paperwork

The passport must remain valid for six months beyond the return date for most destinations. Electronic visas (e-Visa) are available for Turkey, India, Cambodia, Sri Lanka, and Tanzania. The European Union's ETIAS system now applies to non-Schengen travellers. For China, Vietnam or Russia, obtaining a visa remains more complex and requires several weeks.

Insurance and health

Travel insurance covering repatriation, medical expenses up to one million dollars, and cancellation is essential outside your home region. Medical repatriation from Asia or Latin America can cost more than one hundred thousand euros. Visit a travel vaccination centre six weeks before departure: yellow fever is mandatory for certain zones of Amazonia and sub-Saharan Africa, antimalarials are required depending on the region.

Photography, faithful memory

Prefer a lightweight mirrorless body rather than a bulky DSLR. Back up your photos every evening to an external drive and to the cloud. Ask permission before photographing people, especially in Southeast Asia and the Middle East. In sacred places (temples, mosques, churches), follow the posted rules: some sites forbid photography or charge an additional fee.

Cultural respect

Learning ten phrases in the local language (hello, thank you, please, how much, I would like) transforms the welcome you receive. Research dress codes: shoulders and knees covered in Buddhist and Hindu temples, a headscarf for women in some mosques. Tipping is mandatory in the United States, unwelcome in Japan, optional elsewhere. Bargaining is expected in Morocco, Turkey, India: never in Western Europe.

Budget and planning

For a three-week journey to Peru or Vietnam, budget between $2,500 and $4,000 all inclusive. Iceland, Japan and Norway require a daily budget roughly double that. Book long-haul tickets six months ahead for the best fares, but leave flexibility for accommodation once on the ground: except at high-demand sites like Machu Picchu, where permits are tightly capped.

Travel as a permanent geography quiz

Every destination teaches something: the geology of Iceland, Mayan astronomy, Japanese calligraphy, the caravanserais of the Silk Road. Travelling well means turning each trip into ongoing education. To prepare for or extend the experience, the geography quizzes on SparkleQuiz cover capitals, flags, monuments and natural records: a playful way to keep the subject alive between two departures.

The list could stretch infinitely: the Valley of the Kings in Egypt, Easter Island, Petropavlovsk-Kamchatsky, Victoria Falls, Uluru in central Australia, Chilean Patagonia. Twenty destinations is arbitrary and incomplete. But it is also an invitation to start, to choose the next one, to understand that the planet remains, despite the uniformity of airports and hotel chains, infinitely more vast and stranger than any map can summarise. Safe travels.

Put your knowledge to the test

Twenty destinations make a fine bucket list, and an even better quiz syllabus. Before booking anything, check how well you already know the planet you are about to explore:

• UNESCO World Heritage Sites: Petra, Angkor, Lalibela and the rest of the list
• Around the World in 10 Questions: a quick lap of the globe before the real one
• Asian Wonders and World Deserts: from the Great Wall to Cappadocia
• Africa and Middle East Destinations: Marrakech, Cape Town and beyond
• Extreme Adventure Travel: for those eyeing Fiordland and the Inca Trail
