Mercer Island This Week: Town Center Trick-or-Treat Friday, Holiday Makers Market Ahead (October 26–November 2, 2026)

Halloween weekend is here, and the one official City event on the island's calendar this week is a family favorite. Here's what's on for October 26–November 2.

TOWN CENTER TRICK-OR-TREAT — Friday, October 30, 2026 | 4:00 PM – 6:00 PM | Mercer Island Town Center

Town Center merchants hand out treats to costumed kids in the City's annual family-friendly Halloween event. It's free, and a fun way to see the neighborhood at its most festive.

LOOKING AHEAD — HOLIDAY MAKERS MARKET — Saturday, December 5, 2026 | Time and venue to be confirmed

The City lists the Holiday Makers Market, held in partnership with the Mercer Island Chamber of Commerce, for December 5. 2026 details haven't been posted yet, so check the City or Chamber before you go.

A note on First Friday Art Walk: the monthly Town Center art walk typically falls on the first Friday evening of the month, but a November 2026 date hasn't been confirmed. Check with participating galleries before heading out.

The Farmers Market has finished its 2026 season, so look for it again next spring. For day-to-day listings such as library programs and Community & Event Center classes, see the City's online calendar.

Event details can change, so check with the City of Mercer Island Parks & Recreation or the organizers before heading out. Whether you're a longtime islander or just getting to know Mercer Island, fall is a great time to experience the community. Curious what it's like to live here year-round? I'm always happy to talk.
