10 ultra-contaminated places in the USA you can actually visit

Toxic tourism is a real thing

America has more than 1,300 active Superfund sites, places so polluted they require federal intervention and billions in cleanup costs.

What most people do not realize is that many of these contaminated locations are open to the public. You can walk through ghost towns poisoned by lead, peer into lakes of acid, and stand in craters left by atomic bombs.

These are not theme parks.

They are real places where real damage was done, and visiting them offers a sobering look at what happens when industry runs unchecked.

Centralia, Pennsylvania

A coal fire has been burning beneath this town since 1962.

It started when the borough set fire to a landfill built over an abandoned mine, and flames spread into coal seams underground. The fire now covers 400 acres and reaches temperatures above 1,000 degrees.

Steam rises from cracks in the earth, and signs warn of toxic gases and unstable ground. Pennsylvania condemned the entire town in 1992 and relocated residents with $42 million in federal funds.

Only five people remained by 2020.

Visitors can still walk the empty streets and see where Graffiti Highway once ran before it was buried in 2020.

Berkeley Pit, Montana

This former copper mine in Butte is one of the few places in America where you pay admission to see toxic waste.

The pit is one mile long, half a mile wide, and 1,780 feet deep. Admission is $3.

About 1,000 feet of that depth is filled with acidic water containing arsenic, cadmium, copper, and sulfuric acid. The water is so corrosive it killed an estimated 4,000 geese in 2016 when they landed for a drink.

Scientists have discovered new species of bacteria and fungi living in the pit that produce compounds showing promise against cancer cells.

Love Canal, New York

This Niagara Falls neighborhood became ground zero for the modern environmental movement. Between 1942 and 1952, Hooker Chemical Company dumped 21,000 tons of chemical waste into an abandoned canal.

The company sold the land to the local school board for $1 in 1953, and homes and a school were built on top. By the late 1970s, residents reported unusually high rates of birth defects, miscarriages, and cancers.

President Carter declared a federal emergency in 1978, and 800 families were relocated. The disaster led directly to the creation of the Superfund program in 1980.

Times Beach, Missouri

This small town 20 miles southwest of St. Louis was evacuated in 1983 after discovering its dirt roads had been sprayed with dioxin-contaminated oil.

A waste hauler named Russell Bliss had mixed toxic byproducts from Agent Orange production with used motor oil and sprayed 160,000 gallons on local roads to control dust.

When the nearby Meramec River flooded in December 1982, the poison spread everywhere. The federal government bought out all 2,000 residents for $33 million.

An incinerator burned 265,000 tons of contaminated soil, and in 1999 the site reopened as Route 66 State Park.

Picher, Oklahoma

At its peak in 1926, this lead and zinc mining town had 14,000 residents. By 2010, it had 20.

Mining operations left behind 70 million tons of toxic tailings in giant piles called chat, and a 1994 study found that 34% of local children had lead poisoning.

A 2006 Army Corps of Engineers report determined that 86% of the town’s buildings sat on ground that could collapse into abandoned mine shafts at any time.

An EF4 tornado in 2008 destroyed 150 homes and killed six people.

The federal government bought out the remaining properties, and Oklahoma officially dissolved the city in 2009. You can still drive through the empty streets today.

Cancer Alley, Louisiana

This 85-mile stretch of the Mississippi River between New Orleans and Baton Rouge contains more than 200 petrochemical plants and refineries.

In 2014, the EPA found that a neoprene plant in Reserve emitted 99% of the nation’s chloroprene pollution. The area processes about 25% of all petrochemical products in the United States.

Communities like Reserve and St.James Parish have cancer risks from air pollution that are 700 times the national average in some neighborhoods.

Environmental justice groups now offer toxic tours.

Hanford Site, Washington

The B Reactor here produced the plutonium used in the Trinity test and the bomb dropped on Nagasaki. Built in 1943 as part of the Manhattan Project, it was the world’s first full-scale nuclear production reactor.

The site is now part of the Manhattan Project National Historical Park and offers free tours from April through November.

Visitors board a bus in Richland and spend four hours exploring the reactor and surrounding areas. Note that tours were suspended for 2025 due to construction, so check the schedule before planning a visit.

Nevada Test Site, Nevada

Between 1951 and 1992, the federal government detonated 928 nuclear weapons at this 1,350-square-mile facility northwest of Las Vegas.

Tours visit Sedan Crater, a 1,280-foot-wide hole created by a 1962 underground test, and Frenchman Flat, where 1950s-era houses were built to test how structures would survive a nuclear blast.

The Department of Energy offers free monthly tours that fill up within days of registration opening. Visitors cannot bring cameras, phones, or binoculars, and tours have been canceled through February 2026 due to funding uncertainty.

Gowanus Canal, New York

This 1. 8-mile waterway in Brooklyn was designated a Superfund site in 2010 after more than a century of industrial dumping left the sediment contaminated with coal tar, heavy metals, and PCBs.

The canal also receives 300 million gallons of raw sewage overflow each year. Despite all this, the Gowanus Dredgers Canoe Club offers free paddle tours and walking tours.

A $500 million cleanup is now underway to dredge contaminated sediment and build retention tanks. The neighborhood has embraced its toxic identity with bars and restaurants naming drinks after the murky green water.

Newtown Creek, New York

This 3.8-mile waterway between Brooklyn and Queens was once one of the busiest industrial corridors in America.

Oil refineries, petrochemical plants, and factories lined its banks for over a century, and the city has dumped raw sewage into it since 1856.

An underground oil spill discovered in 1978 leaked an estimated 17 to 30 million gallons into the surrounding soil. The EPA designated it a Superfund site in 2010.

Today, the Newtown Creek Nature Walk offers public access to the shoreline, and community groups lead canoe and kayak tours through the polluted waters.

State health officials say paddling is safe as long as you avoid contact with the water.

A Warning and an Invitation

These contaminated sites are not attractions in the traditional sense.

They are cautionary tales carved into the American landscape, places where the true cost of industrialization is written in poisoned soil and polluted water.

Visiting them requires awareness of the risks and respect for the communities still dealing with the consequences.

But for those willing to look, they offer something no museum can replicate: the chance to stand in the places where environmental history was made and see firsthand why it matters.
