Camping and Hiking Spots You Should Never Visit in the US

Organ Pipe Cactus National Monument - Arizona

Organ Pipe Cactus National Monument, a UNESCO Biosphere Reserve bordering the Mexican state of Sonora, showcases a breathtaking array of over 2,000 plant species. Known for its impressive collection of cacti, it’s the only place where the senita and organ pipe cactus grow naturally in the wild. But while the natural beauty is awe-inspiring, the location itself presents significant risks

From 2003 to 2014, much of the monument was closed to the public due to the presence of trafficking organizations. Even today, it’s considered one of the most dangerous national parks in the United States because of its history with smuggling, cartel activity, and violence. Visitors should approach this area with extreme caution. Is it worth the risk? For those who venture here, the unique desert landscapes and rare cacti offer an unforgettable experience—but safety must always come first. Plan ahead, stay informed, and travel with care.
