The Brown Mountain Lights are a series of ghost lights reported near Brown Mountain in North Carolina. The lights can be seen from the Blue Ridge Parkway overlooks at mile posts 310 (Brown Mountain Light overlook) and 301 (Green Mountain overlook) and from the Brown Mountain Overlook on NC Highway 181 between Morganton, NC and Linville, NC. Additionally, good sightings of the Lights have been reported from the top of Table Rock, outside of Morganton, NC. One of the best vantage points, Wisemans View, is about 4 miles from Linville Falls, NC. There is also a Brown Mountain Overlook on North Carolina Highway 181 that was recently improved with help from the city of Morganton for the purpose of attracting those who visit the area to see the lights. The best time of year to see them is reportedly September through early November.

Only superstitious people think they are ghosts,
scientific people know they are UFO's piloted by Bigfoot!
There's a lot of interesting folklore and speculation about them.
