Days and nights of ghoulish delight are planned for the Civil War-era fort beside Key West's Atlantic Ocean shore. This year three spooky sections of the enchanted citadel will be the stage for live "shows," treating visitors to otherworldly celebrations not suitable for mere mortals. Events will take place Oct. 17-19, 23-24, 26 and 30-31, and attendees are encouraged to don devilish costumes. Tricks and treats for the little ones are planned for Kid's Day, scheduled Sunday, Oct. 19, from 5-7 p.m. Kid's Day entry is free with park admission. Admission to the haunting is $13 per adult, $10 for military personnel, $8 for kids and free for children under age 5. Hours are 8-11 p.m. (midnight on Halloween).
