As Halloween draws near, we have ghosts on our minds. And what better place to hunt for ghosts than in the oldest city in the United States? Come with us to St. Augustine, Florida, a seaside town about an hour north of Daytona Beach, as we search out some spooky spots for the season. (Feature photo: Flickr/Rachel Kramer) We'll start with the obvious, because you can't miss it! The Castillo de San Marcos is one of the Old City's largest and most popular tourist destinations. It's also, according to ghost experts, quite haunted. If the past returns to Castillo de San Marcos, it's with good reason: this massive Spanish fort has been guarding the city since the 17th century. The Castillo de San Marcos looms over St. Augustine's waterfront. Photo: flickr/Rachel Kramer Today it's a hugely popular tourist attraction, and not just for its history. Ghost stories abound at this fort, from sightings of Spanish colonial troops still on night patrol, to the touch of cold hands in the dungeons. The fort is featured in the Travel Channel series Ghost Adventures. Luckily, even if you do get spooked at the Castillo, you'll have plenty of (living) company – about 650,000 visitors a year pass through its gates. Castillo de San Marcos National Monument is open every day but Thanksgiving and Christmas and entrance costs $7 per adult (children 15 and under are free with adult). You'll find a variety of events on the calendar, such as the Historic Weapons Demonstration, just in case you don't see any ghosts while you're there. The Old City's cemetery is the perfect place to tell ghost stories after dark, and that's just what ghost tour operators do.

One is an adolescent girl in a flowing white gown, supposedly the victim of yellow fever, who floats through the cemetery, occasionally waving hello to guests, after midnight. Another is the ghost of Judge John Stickney, who has apparently been searching for his stolen gold teeth for the past century. Cemetery visitors often report “orbs,” glowing balls of light, showing up in their photos after their visit – ghost hunters say orbs are a sure sign of paranormal activity. The best way to visit the Huguenot Cemetery is on one of St. Augustine's many ghost tours (links at the end of this post). Due to preservation concerns, the cemetery isn't open to regular foot traffic. St. Augustine's popular Oldest Wooden School House. Pay no attention to that woman in the window: she's a mannequin. That green orb on the other hand… Even some of the city's favorite school field-trip locations aren't immune from the local ghosts. The Oldest Wooden School House is said to be haunted by a young woman in 19th-century clothing, who gazes out the second floor window. The Old Drugstore is full of fun old-fashioned elixirs, but local legend also says the site is haunted by a Native American chief, since it's built on a burial ground. A lantern-light tour of Potter's Wax Museum would be alarming enough without the ghost stories, but the Ghosts and Gravestones tour throws them in anyway. And The Old Jail is frequently called the most haunted site in St. Augustine, with cold spots, unexplained scents, banging noises, and strange lights. If you're ready to add some “boo!” to your St. Augustine trip, the easiest way to take in all these haunted sites (and learn a little history) is through a ghost tour like the ones listed below.
