World's 10 Deadliest National Parks: Wildlife, War, and Natural Disasters

The world's national parks are supposed to be sanctuaries—places where wilderness is preserved and visitors come to witness nature in its most pristine form. But sanctuary is a fragile thing. A walk through ten of the planet's deadliest parks reveals that the greatest threats to human life often have little to do with fangs or claws. Yes, saltwater crocodiles patrol the waters of Kakadu in Australia's Northern Territory, and yes, a 47-year-old man was taken by one at Cahill's Crossing in 2017. But fewer than 50 people have been killed by crocodiles across all of Australia since 1969. The real danger in many of the world's most visited protected areas comes from sources far harder to predict or avoid: armed conflict, political collapse, and the slow destruction of ecosystems caught in the crossfire of human violence.

Wildlife remains a genuine hazard in certain parks, though the statistics often surprise. Komodo National Park in Indonesia harbors three-meter-long monitor lizards with venom-laced bites and bacteria that can turn wounds septic. An eight-year-old boy died there in 2007, and a 31-year-old man in 2009. Kaziranga National Park in India's Assam state is home to greater one-horned rhinoceroses weighing up to 2,700 kilograms—animals that charge at 25 miles per hour and have killed park staff in recent years. A photographer visiting the park described being pursued by what he called an "organic tank," then nearly shoved off the road by a female protecting her territory. The Sunderbans in India, a river delta shared between India and Bangladesh, has earned a darker reputation: tigers there have killed an estimated 3,000 people over the past fifty years, though the actual number remains disputed. Some estimates put the death rate at 60 annually; the Forest Department claims it is closer to two or three. Whether these big cats are man-eaters by preference or simply desperate from a scarcity of natural prey in the brackish waters remains unclear.

But wildlife, for all its lethal potential, pales beside the threats posed by human conflict and state collapse. Tayrona National Park in northern Colombia received 600,000 visitors annually until February of this year, when authorities closed it due to the "advance of armed groups." The park's management reported threats against staff, intimidation at entrances, roadblocks, and illegal fees imposed by armed actors. The main protagonists are the Clan del Golfo, a 10,000-member criminal organization, and the Self-Defence Forces of the Sierra Nevada. The park itself—home to cotton-top tamarins, jaguars, caimans, and poison-dart frogs—remains inaccessible to the public it was meant to serve.

The situation in Ukraine's Sviati Hory National Park is grimmer still. Located in the north near the Russian border and directly in the path of four years of warfare, the park has been devastated. Reuters reported in 2024 that 80 percent of its 12,000 hectares of forest had been damaged or destroyed by fire and Russian munitions. The park director, Serhiy Pryimachuk, described it as once being "a rare and beloved beauty spot in a heavily industrialised region." The eagles, otters, and stoats that inhabited it may no longer exist there, if they exist at all.

In the Democratic Republic of the Congo, Kahuzi-Biega National Park—renowned as the world's best location to observe eastern lowland gorillas—has been ravaged by civil conflict. M23 rebels took control of parts of the park last year, triggering a surge in illegal logging for charcoal and timber. Since the mid-1990s, the security crisis in the DRC has driven a nearly 80 percent decline in Grauer's gorilla populations. In 2015, scientists estimated only 3,800 remained.

Natural forces add another dimension of peril. Bromo Tengger Semeru National Park in Indonesia sits atop two active volcanoes. Last November, Mount Semeru erupted ten times in succession, forcing the evacuation of more than 900 people, including 170 climbers, as ash, lava, and rocks cascaded 13 kilometers down its slopes.

The Darién Gap—a 100-kilometer break in the Pan-American Highway that cuts through dense rainforest and marshland on the border between Central and South America—represents a different kind of crisis. In 2023 alone, more than 500,000 people, many fleeing violence and economic collapse in Venezuela, Ecuador, and Haiti, attempted to cross it. At least 141 died in the attempt, though the true number is almost certainly higher. The park itself remains rich with wildlife—tapirs, jaguars, giant anteaters—but it has become a corridor of desperation and death.

What emerges from this survey is a sobering truth: the parks most likely to kill you are not those with the most venomous snakes or the largest predators. They are the ones caught between states, torn by conflict, or overwhelmed by human migration. A saltwater crocodile can be avoided by staying ten meters from the water's edge. A charging rhino can be outrun in a vehicle. But a park closed by armed groups, or one buried under ash from a volcano, or one serving as a transit route for half a million desperate people—these threats cannot be managed by caution alone. They require something far more difficult: the restoration of peace, the stabilization of nations, and the recognition that protected areas cannot remain protected when the regions surrounding them are in collapse.
