If you favor activities that are likely to keep you from sleeping, these tours are for you. Not only are the various outings held in the evening, but they're all concerned with ghouls. The Ghosts of Austin Downtown Walking Tour explores the stories of those that even death couldn't separate from downtown, while the tavern-crawl Haunted Sixth Street Tour capitalizes on the spirits that liked their spirits (and visitors who like both the spectral and the alcoholic manifestations). Austin Ghost Tours has also teamed up with the Austin Museum of Art for a special 90-minute Haunted History Walking Tour, featuring the museum exhibit "The Disembodied Spirit," the Wooten building, the Old Miller Opera House, and the capitol. A variety of other tours are available as well, so be sure to check the website, and then call ahead to make the required reservations.
