15 Places You Should Never Visit Alone—Even If They Seem Completely Safe
It’s easy to think that every destination listed in travel guides is a picture-perfect spot for a solo adventure. Isn’t the whole point of adventure stepping out of your comfort zone after all? But some places carry a hidden undercurrent of risk. On the surface, they may look Instagram-worthy, but these locations might just make your solo escapade feel almost as real as a survival reality show.
Whether it’s their isolation, reputation for crime, or unpredictable elements, there are spots on this planet where flying solo isn’t just a bad idea—it’s a downright dangerous one. Here’s a closer look at places where you’re better off having a buddy—or maybe just not going at all.
Snake Island, Brazil

Welcome to Ilha da Queimada Grande, better known as Snake Island. Sounds charming, right? Thousands of golden lancehead vipers, among the deadliest snakes on Earth, live on this Brazilian island. No human lives here (for obvious reasons), and even scientists tread carefully when they visit. If you go alone and get bitten, the nearest hospital is hours away—assuming you even make it back to the boat.
Mount Hua Shan, China

China’s ancient mountain is famed for its perilous ‘plank walk in the sky’, with hikers walking on wooden boards bolted to cliffs. Even thrill-seekers can’t keep their nerves steady with no guardrails and dizzying heights. Solo hiking here isn’t just lonely—it’s potentially your last hike ever. Bring a friend to hold your hand or, better yet, your harness.
Death Valley, California

Death Valley isn’t a walk in the park. Temperatures here can soar to 130°F, and it’s one of the driest places on Earth. Dehydration and heatstroke can happen faster than you can say “bottle of water,” if you’re not properly prepared. If your car breaks down in this vast desert, you’ll wish you had someone to share your dwindling water supply with.
North Sentinel Island, India

This remote island in the Indian Ocean is off-limits for a reason. The Sentinelese, an isolated indigenous tribe, has a strict “no visitors” rule and they enforce it — with arrows. Even if you’re the world’s most charming traveler, they won’t roll out the welcome mat. Go alone, and you’ll likely be remembered as that tourist who should’ve stayed home.
The Catacombs of Paris

Under the romantic streets of Paris is a labyrinth of dark, bone-lined tunnels. While they’re a spooky adventure, you could easily get lost. People have wandered these winding passages and never found their way out. A guide isn’t just helpful here—it’s a lifeline.
The Amazon Rainforest

This lush, vibrant jungle is filled with wonders and dangers. The Amazon is not a place for a lone traveler, from fast-moving rivers to venomous creatures—you name it. On top of that, the sheer density of the forest would make it easy to lose your bearings. Teaming up with a guide or group could save you from becoming an accidental jungle resident.
La Perouse Strait, Russia

Famed for its frightening currents and deadly weather, this stride of icy water separates Russia from Japan. It’s not a place for casual paddling or boating, especially if you’re by yourself. Getting stranded here means you’re stuck in the middle of nowhere, with freezing waters and no one to help.
Pripyat, Ukraine

Urban explorers may think the eerie, abandoned city of Pripyat, near the Chernobyl nuclear disaster site, would be the perfect spot. However, radiation hotspots and structures in ruin represent serious risks. Without a guide, it’s easy to wander into unsafe areas—and you definitely don’t want to make Chernobyl your final resting place.
Darien Gap, Panama-Colombia Border

This dense jungle between Panama and Colombia is well-known for lawlessness, wildlife, and drug trafficking routes. While it’s a shortcut on paper, solo travelers often find themselves caught in life-threatening situations here. The danger isn’t just the terrain—it’s who (or what) you might encounter along the way.
Old Mines of Nevada

There are abandoned mines all over Nevada, some of which look like playgrounds for history buffs or adventure seekers. However, these old shafts are in extremely unstable condition; they contain unseen dangers like collapsing tunnels or toxic gas pockets. It’s not worth wandering in alone unless you’re looking to star in your own ghost story.
The Bermuda Triangle

Ah, the Bermuda Triangle—that infamous stretch of ocean where ships and planes have simply disappeared without explanations. While its spooky reputation is hotly debated, it’s still a risky spot for solo sailors or pilots. If something goes wrong, there’s no one to radio for help.
Kokoda Trail, Papua New Guinea

The dense jungle of Papua New Guinea includes this 60-mile trail steeped in history and challenges. The problem isn’t just the rugged terrain, but the unpredictable weather and health risks such as malaria. Going alone can turn this journey from a tribute to WWII soldiers into a personal battle for survival.
Alaska’s Backcountry

Alaska’s wilderness is beautiful, but its isolation can be brutal. It’s a bad idea for solo adventures, because of wild animals, extreme weather, and lack of cell service. Rescue could take days—or more—if something goes wrong. It’s best explored with someone who knows the ropes.
Cape Town’s Table Mountain

This South African icon attracts climbers and hikers from around the world. But beneath the stunning vistas lies a darker side—rapidly changing weather and treacherous trails. Even experienced hikers have fallen victim to its dangers. Without a buddy to call for help, a solo trip here could end in disaster.
Surtsey, Iceland

This tiny volcanic island is a UNESCO World Heritage site, but it’s strictly regulated to protect its ecosystem. Going solo isn’t just risky—it’s illegal. Scientists are the only visitors allowed, and even they travel in teams. It’s a fascinating place, but this is one adventure best left to the experts.
