Off-limits to the public for nearly a quarter of a century, the infamous observation deck of the UT Tower—where gunman Charles Whitman went on a deadly shooting spree in 1966—now has a webbed safety dome. Billed as self-guided tours, these excursions to the top of the tower are really supervised visits, although a guide gives a short, informative spiel and stays on hand to answer questions. It would probably be better if these visits—about 45 minutes—were half as long and half as expensive. Note: You are permitted to bring a camera, binoculars, or phone to take advantage of the observation deck’s spectacular 360-degree view of the city and environs, but you must leave behind everything else, including purses, camera bags, tripods, and strollers. (Lockers are available at the Texas Union for $1.)
