The postcard view has never been the whole story. Half the reason we travel isn’t to relax on a beach or admire a famous monument—it’s to stand at the edge of something that shouldn’t exist. A crater that’s been on fire for fifty years. An island so contaminated you need a permit just to walk its streets. Visitor numbers to sites associated with death, decay, or danger have climbed steadily over the past three decades. We’re wired for the odd, and the tourism industry has noticed.
These aren’t your average bucket-list landmarks. What makes these places strange isn’t spectacle alone—it’s the collision of human error, natural forces, and our inability to look away. Here are ten of the strangest tourist attractions globally, each with the visiting details no one tells you until you’re already planning the trip.
1. Door to Hell (Darvaza Gas Crater), Turkmenistan
A Soviet drilling accident in 1971 punched through a cavern of natural gas, and geologists decided the safest move was to light it on fire. They thought it would burn out in weeks. It’s still going. The Darvaza crater spans 230 feet across and has become Turkmenistan’s most photographed landmark, pulling over 10,000 visitors annually to stand at the rim of a desert inferno.
Getting there requires a 4WD convoy from Ashgabat, a government-approved guide, and patience with Turkmenistan’s famously opaque visa process. The government has announced plans to extinguish it multiple times—most recently in 2022—but the flames persist. Best visited at dusk when the glow is sharpest against the sand.
2. Centralia, Pennsylvania, USA
The town above a coal seam that’s been burning since 1962. What started as routine landfill maintenance spiraled into an underground inferno that cracked roads, filled basements with carbon monoxide, and eventually condemned the entire town. Fewer than five residents remain. Centralia is technically off-limits, but the famous graffiti highway stretch of Route 61—where steam vents through fractured asphalt—draws thousands of visitors each year despite being on private property.
The Pennsylvania Department of Environmental Protection monitors the fire but has no plan to extinguish it; estimates say it could burn for another 250 years. Visiting is legal on the public roads, though the cracked pavement and sudden sinkholes are genuine hazards. Go in fall when the smoke is most visible against cooler air.
3. Hashima Island (Gunkanjima), Japan
An abandoned coal-mining island off Nagasaki that looks like a concrete battleship rising from the sea—hence the nickname “Battleship Island.” At its peak in 1959, over 5,000 workers lived on less than 16 acres, making it one of the most densely populated places on Earth. The mine closed in 1974, and the island was left to decay. The site was inscribed as a UNESCO World Heritage Site in 2015, acknowledging both its industrial history and the forced Korean labor used during WWII.
You can only visit on a sanctioned boat tour from Nagasaki, weather permitting. Access is limited to a small concrete pier and a single walkway—most of the island remains too structurally dangerous to explore. Tours book months ahead in peak season.
4. The Catacombs of Paris, France
Six million skeletons arranged in tunnels beneath the city, stacked like cordwood along 200 miles of former limestone quarries. The bones were moved there starting in 1786 when Paris’s overcrowded cemeteries became a public health crisis. What makes the catacombs strange isn’t just the volume of human remains—it’s the care taken to arrange them. Femurs stacked in neat rows, skulls forming decorative patterns, plaques with morbid poetry.
The official tour covers about a mile and requires descending 131 steps into cool, damp air that stays around 57°F year-round. The illegal “cataphile” network of unmapped tunnels is a separate world entirely—do not attempt it without a guide who knows the exits. Book tickets weeks in advance; they sell out daily.
5. Fly Geyser, Nevada, USA
A man-made accident that turned into an alien landscape. In 1964, a geothermal test well was abandoned without being properly capped, and mineral-rich water began erupting through the surface. Decades of calcium carbonate deposits built terraces in shades of red, green, and yellow—colors caused by thermophilic algae that thrive in the scalding water.
Fly Geyser sits on private land within the Black Rock Desert, and access was restricted until 2016. Guided tours now run through the Nevada Museum of Art, but they’re seasonal and limited to preserve the fragile formations. Expect surreal colors and crowds of photographers at golden hour.
6. Varosha, Cyprus
A beach resort frozen in 1974. When Turkish forces invaded northern Cyprus, the residents of Varosha fled, and the Turkish military fenced off the entire district. For nearly fifty years, it sat untouched—hotel lobbies still set for guests who never arrived, storefronts with 1970s inventory rotting behind glass. Partial reopening began in 2020, but much of Varosha remains a militarized ghost town.
You can now walk a controlled section of the beachfront, but photography restrictions are enforced, and straying from marked paths can land you in legal trouble. The ethics here are tangled—this is disputed territory, and tourism dollars fund the occupation. Tread carefully.
7. Lake Natron, Tanzania
A salt lake so alkaline it can calcify animals that die in its waters, preserving them in eerie mineral shells. Photographer Nick Brandt documented the phenomenon for his series on East African wildlife, and the images went viral—birds and bats turned to stone along the shoreline. The lake’s pH hovers near 10.5, fed by volcanic minerals from the Great Rift Valley.
Despite the harshness, Lake Natron is also the primary breeding ground for East Africa’s lesser flamingos, which thrive in the caustic water that keeps predators away. Visiting requires a 4WD from Arusha and a local guide; the nearest lodging is basic. The best (and least punishing) time to visit is June through October, when temperatures drop below oppressive.
8. Chernobyl Exclusion Zone, Ukraine
The 1,000-square-mile zone around the 1986 nuclear disaster, now one of the most visited dark tourism sites in the world. Pripyat, the abandoned city built for plant workers, draws tens of thousands annually to walk through crumbling schools, rusting amusement parks, and apartment blocks reclaimed by forest. Radiation levels are monitored closely, and official tours keep visitors on paths deemed safe for short exposure.
Access was formalized after Ukraine opened the zone to tourism in 2011, and operators run day trips from Kyiv. As of 2026, tours have resumed post-conflict with updated safety protocols. You’ll pass through two military checkpoints, carry a dosimeter, and sign a waiver. The strangeness isn’t the radiation—it’s how ordinary it all looks. A city stopped mid-sentence.
9. Salar de Uyuni, Bolivia
The world’s largest salt flat, 4,000 square miles of blinding white hexagonal tiles that stretch to the horizon. During the rainy season (December to April), a thin layer of water turns the surface into a perfect mirror, erasing the line between earth and sky. It’s disorienting and surreal—a landscape Instagram was built for.
Beneath the salt lies one of the world’s largest lithium reserves, and the tension between tourism and mining is sharpening. Tours run from the town of Uyuni, ranging from day trips to multi-day expeditions that include high-altitude lagoons and flamingo colonies. Altitude sickness is real at 12,000 feet; acclimatize in La Paz first.
10. Kawah Ijen, Indonesia
A volcanic crater lake the color of antifreeze, glowing electric blue at night from combusting sulfuric gas. Miners climb into the crater daily to extract sulfur by hand—one of the most dangerous jobs on the planet—while tourists hike up at 2 a.m. to photograph the blue flames. The juxtaposition is jarring: natural wonder meets human desperation.
The hike is steep, and sulfur fumes can be overwhelming without a gas mask (rent one at the base). Guides are required, and the trek takes about two hours each way. Go between April and October to avoid monsoon rains that make the trail treacherous. Respect the miners’ space—they’re working, not performing.
How we ranked these
We prioritized accessibility (can you actually visit legally and safely?), geographic diversity, and the “huh” factor—the collision of human error, natural oddity, or historical accident that makes a place genuinely strange rather than just remote.
Frequently asked questions
What are the most dangerous tourist attractions in the world?
Kawah Ijen’s sulfur fumes, Centralia’s unstable ground, and certain zones in Chernobyl carry real risk. Most “dangerous” attractions mitigate hazards with guides, permits, or restricted access—the risk is usually manageable if you follow the rules. The bigger danger is ignoring those rules.
Are weird tourist attractions safe to visit?
It depends entirely on the site. Official tours to Chernobyl, Hashima Island, and the Paris Catacombs are heavily regulated. Abandoned sites like Centralia or informal access points carry higher risk. Check current conditions, book with licensed operators, and don’t assume “people go there” means “it’s safe.”
Why do people visit strange places?
Novelty-seeking, the Instagram economy, and a hunger for places that feel genuinely unusual in an over-documented world. The appeal is partly psychological—we’re drawn to places associated with danger or decay, what researchers call “dark tourism.” It’s not new; it’s just accelerated by social media and the ease of travel. Unusual attractions generate more interest per visitor than conventional landmarks, and that attention translates to economic value for remote regions.
The strangest places often weren’t designed to be destinations at all. They’re accidents, aftermaths, or natural extremes that happened to catch our attention. If you’re wired to seek them out, do it with respect for what made them strange in the first place—and a realistic sense of what you’re walking into.
