Trick or Trees brings Zionsville families to Elm Street Green Park for a costumed walk along a Trick-or-Treat Trail, with goodies from local partners along the way. Kids can roast marshmallows at the fire pit, try hands-on fall activities, science experiments and games, and walk the Pumpkin Path, where scarecrows decorated by local businesses line the way and kids vote for their favorite.
The event is for ages 2 to 12, with timed entry slots from 9 to 11 a.m. and last check-in at 11:30 a.m. Every participating child must be registered, including children under 2, who attend free. Online registration closes at 4 p.m. Friday, Oct. 23, and limited day-of admission is $7 per child, cashless only.
As of Oct. 12, the 9:30, 10 and 10:30 a.m. entry times are full, and the 9 and 11 a.m. entry times still have openings.
