Starting Sunday, Nov. 4, the trails and adjacent parking lots will remain open until 9 .m. daily until March 9.

If you're looking for an alternative to skating at Millennium Park this winter, look up. Way up-94 stories, to be exact. Touted as the World's Highest Ice Skating Rink, the 94th floor of the John Hancock Center gives ice skaters a bird's-eye view of the city and the lake.

At 20 feet by 45 feet, the rink is probably too small to be your solo destination of the day, but paired with a trip to see the view from the Hancock, it's a nice way for kids to burn off energy while parents enjoy the great view. And because it's synthetic ice, skaters stay warm and don't get wet.

The rink is scheduled to be open for skating from 9 a.m.-11 p.m. through April 18. A 25-minute skate session costs $6 (in addition to the cost to get into the Hancock Observatory). You can bring your own skates or rent some there for a dollar.

Free, fun and educational arts project for kids. Projects change bi-weekly.

See a toy so amazing, so unbelievable, it has the power to transform into anything you want it to be. Enter a world where imagination rules, and ordinary becomes extraordinary.

Build a snow fort, throw snowballs, dress up a snowman and ice skate - all inside.
The brand new "ice" rink has more space to skate in your socks.

A new traveling exhibit created by Children's Museum of Pittsburgh that links familiar childhood objects to a process of manufacturing that combines people, ideas and technology. Inspired by the factory tour segments from Mister Rogers' Neighborhood, the exhibit offers hands-on activities using real factory tools and machines to create objects including crayons, a baseball bat and a matchbox car, just to name a few.

The exhibit features the illustrations of W. W. Denslow, a Chicago resident whose famous illustrations helped to inspire the design of the classic 1939 MGM film starring Judy Garland. The bright and colorful exhibit provides a variety of learning opportunities and hands-on activities within a three-dimensional representation of Denslow's distinctive illustrations.
