The Bats and Ghosts 5k Tour unveils a darker side of Austin that often goes overlooked. Austin was home to the first documented serial killer in America. For about one-hour in the evening, meeting at 7:30pm, you will explore that theory along with dozens of other murders, suicides, and hauntings throughout the Downtown, led by a professional guide. You will also visit the largest bat colony in North America on the Congress Ave Bridge where you'll see a 1.5 million bat exodus for the night's hunt. Many of the sites and stories on this tour are morbid and macabre, so if you don't like being scared, this isn't for you.
