3. Cliffs of Moher, Ireland
Ireland is known for its beautiful landscape, particularly its picturesque coastline. The Cliffs of Moher reach a maximum height of 700 feet, but with the huge vertical drops right into the sea and frequent high winds, you certainly won’t want to veer too close to the edge. The cliffs are a popular tourist destination, but they also have a reputation of attracting self-destructive and even suicidal behavior. Don’t be silly around here, or one false step could prove deadly.

4. Chernobyl, Ukraine

You might not think of the site of the world’s worst nuclear accident is a tourist draw, but Chernobyl is now open to curious visitors by way of expensive guided tours. The whole region, spanning some 1,000 square miles, was evacuated in 1986 due to the devastating explosion at the local nuclear power plant, and the area has been largely uninhabited ever since. However, the danger comes not so much from radiation anymore, but the countless precariously abandoned buildings. Don’t stray from the established paths and you should be okay.
