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.
