Union Station will become a party palace for ghosts and goblins at the first-ever Boo!-nion Station: a free Halloween hoopla. The event will take place on Union Station’s South Patio on Saturday and Sunday, Oct. 27-28, from noon to 6 p.m. on both days.

Dress up in your most haunting or hilarious costume and enjoy family-friendly activities such as the Zombie Zone Hay Maze, Treats-on-Track Trail, Creepy Craft Camper and more!

Furry friends are also welcome — there will be a pet parade and costume contest each day at 3 p.m. Do keep in mind that if you’re bringing your pet via Metro, they’ll need to ride in a secured carrier before making their Boo!-nion Station debut.

To get to Union Station, take the Gold, Red, Purple or Silver Line. Union Station is also served by multiple Metro and municipal buses, Metrolink, Amtrak and Metro Bike Share. For more route and connections, use the Trip Planner at metro.net.
