Halloween 2026 in the Treasure Valley: Trunk-or-Treats & Events
Looking for a full rundown of trunk-or-treats and family-friendly Halloween events across the Treasure Valley this year? Halloween weekend 2026 runs from Thursday, October 29 through Saturday, October 31, and the valley is packed with options from Nampa to Star: downtown trick-or-treating, dealership and neighborhood trunk-or-treats, costume parades, the zoo after hours, and the haunted straw maze out on Scism Road. Below is the practical list by day, with the weekend weather outlook so you can plan costumes and rain gear. The dates and times were current as of late October 2026, and you should confirm every event with its organizer before you head out.
Plan for the weather
The weather outlook
Forecasts for the Boise area as shared by KBOI 2 News and AccuWeather. A cool, mostly dry start to the weekend turns showery by Halloween evening, so plan the rain gear around Saturday night.
Thursday, October 29
Mostly sunny and mild
Highs around 60 for the first evening of trunk-or-treating.
Friday, October 30
Cloudier with a chance of showers
Highs in the mid-50s, so a light layer under the costume is a good idea.
Saturday, October 31
Showers most likely in the evening
Rain chances increase through the day, with showers most likely during the evening. Bring rain gear over costumes.
Weather can change quickly in the valley in late October, so check the forecast again on the day of any outdoor event.

Stay dry, stay visible
Tips for a dry, safe Halloween
With showers most likely Saturday evening, a little planning keeps the night fun instead of soggy. Four things we would do for any trunk-or-treat route, out in town or out on the acreage.
Rain gear over costumes
Saturday’s showers are most likely in the evening, right at trick-or-treat time. A rain shell worn over the costume keeps the outfit visible and dry instead of soggy by the third stop.
Umbrella-friendly strollers
If you are pushing a stroller, bring one with a canopy and a rain cover, and check both before you head out. A dry, comfortable ride means the little ones last longer.
Flashlights and reflective tape
Several events run after dark, from the zoo to the haunted maze. Add glow sticks or reflective tape to costumes and carry a flashlight so drivers and other families can see the kids.
Confirm with every organizer
Times, capacity, and weather plans can change at the last minute. Before you drive across town, confirm the event is still on and that the details above have not moved.
From Paul Knighton
See you out in the acreage communities this weekend.
Halloween is one of the friendliest nights of the year in the Treasure Valley, from the lit-up driveways on acreage roads to the trunk-or-treats in town. I plan to be out and about in the communities this weekend, and if anything here points you to a favorite event, enjoy it. For anything home-related, big or small, reach me at MORE Realty on the contact page anytime, or call or text (208) 369-7447.
