Once the tallest building in the world, the Sears Tower (officially renamed the Willis Tower) now has to settle for second-highest in the Americas alone, behind New York City's One World Trade Center (and even those are after a semantic battle with Toronto and the CN Tower). The Hancock Observatory (see Near North) has a nicer view of the city, but the Sears Tower offers an incredible view of its own from "The Ledge", which lets visitors walk out in a transparent balcony suspended 1,353 feet above the street. To avoid the crowds, visit after 4PM.
Apr-Sep 9AM-10PM, Oct-Mar 10AM-8PM; open every day of the year, including holidays · $22, $11 children; express line tickets $30 · Wheelchair accessible
Hancock Observatory
360-degree view from the 94th floor. Not quite as high as the Sears Tower Skydeck, but with a better view, and from January to March, an ice-skating rink! For drinks, see the Signature Room below.

Nature museum Near South The largest museum on the campus; highlights include SUE, the largest Tyrannosaurus Rex skeleton in the world, and the man-eating Tsavo lions. Part of the collection came directly from the 1893 World's Columbian Exposition, adding a layer of intrigue to all of those dusty old animals. Another highlight is the great, kid-friendly Egyptian exhibit, and the Hall of Gems will impress, too. Traveling exhibitions tend to be excellent, so this is one place where it's worth shelling out for the extra shows.
9AM-5PM daily, last admission 4PM; closed Dec 25 · General admission $30 adults, $23 children, $27 students; Admission including some/all special exhibits is $43 adults, $32 children, $38 students · Wheelchair accessible
One of the premier museums in the U.S. — and with the opening of the sensational new Modern Wing, it's one of the largest, too. Set aside a whole day and arrive early! Iconic pieces on display include "American Gothic" by Grant Wood (the stoic farm couple), "Nighthawks" by Edward Hopper (the late-night diner), Georges Seurat's pointillist masterpiece "Sunday Afternoon on the Island of La Grande Jatte". The Art Institute also boasts the world's best collection of Impressionist painting outside of France. But there's a lot more to discover, including a great selection of early 20th-century painting, architecture, and photography, as well as archaeological finds covering 5,000 years of art and cultural history.
