Do you have what it takes to soar three stories up? Test your agility, strength and nerves on our indoor Ropes Course overlooking historic Union Station. More than 90,000-cubic feet of climbing space and 30 obstacles take you almost to the top of the trainshed. Feeling really brave? Try the SkyRailTM, a 100-foot long rigid zip line that glides 50 feet above the Union Station lobby. You are in control of where to go and what to do, making this a sure hit for adventurers of all ages and skill level! A miniature version of the course, Sky Tykes, is available for our youngest guests who are under 48″ tall. Guests 12 and younger must be accompanied by a paid adult 18+ and all participants must wear shoes with a closed back.
