Mercer Island has lots of Halloween fun in store for kids and families! We’ve compiled a list of the spooktacular upcoming events ahead, and many of them are free! So gather your ghouls and goblins, and don’t forget to wear your costume!

Youth Theatre Northwest presents The Halloween Detective and the Case of the (Not So) Haunted Mansion
October 21 – 29
Saturdays 10 am – 2 pm & Sundays 1 – 3 pm
Emmanuel Episcopal Church, 4400 86th Ave SE
Cost: $10 for kids; free for parents/guardians

Madame Crocosmia’s home was once the scariest mansion around, with folks coming from far and wide to tour its haunted halls. But the Halloween fun ended the day all the scary disappeared. Where did it go? No one knows, but life hasn’t been the same since. With their loss of fright, the ghosts now spend all day making really terrible jokes. No one has paid for a tour in ages, so if the ghosts can’t find their scary, Madame could lose everything! Detective J.L. Pinkerman is determined to solve this case, but he’ll need the help of some junior detectives to sort all this out. Can Pinkerman count on you to save Halloween?

In contrast to a traditional haunted house, Youth Theatre Northwest’s Halloween activity is a non-scary, 30 minute guided adventure specifically created for the most imaginative tots, preschoolers and early elementary age children (ages 3 – 8). This fun detective story, paired with your child’s problem solving skills, will make for an incredibly creative afternoon where your child gets to save the day.

Halloween costumes are encouraged! Also, please note that The Halloween Detective is an outdoor, rain or shine event. All guests are encouraged to dress weather appropriate and wear suitable shoes.

Pioneer Park, Island Crest Way and SE 68th Street
Cost: Free! (Carved pumpkin donations encouraged)

This year is the 2nd Annual Mercer Island Pumpkin Walk! The event will be starting an hour earlier this year, so families with younger kids can take a daylight stroll to see the pumpkins. Starting at the Northwest Quadrant of Pioneer Park, take a walk along NW Perimeter Trail to see a glowing display of carved pumpkins for all ages to enjoy! No flashlights or headlamps, and costumes are optional. Glow stick necklaces and hot chocolate will be provided for the kiddos while supplies last.

The community is encouraged to contribute pumpkins to help make this event a success again this year! If you’d like your carved pumpkin to be on display, you can drop it off that day anytime between 9am and 4pm. Meet at the corner of SE 68th St. and 84th Ave SE. They are also still looking for volunteers for this year’s event!
