Halloween weekend brings several family-oriented activities within reach of Westphalia, from decorated-car celebrations to a free horse show and farmers market. The listings below focus on Saturday, October 31, and Sunday, November 1; Friday evening events that were already underway when this guide was prepared are not presented as upcoming activities.
Hallelujah Day (Truck or Treat)
Saturday, October 31 | 11 a.m.–2 p.m. | Greater Saint John Cathedral, 11425 Old Marlboro Pike, Upper Marlboro, MD 20772.
The organizer's event listing advertises decorated vehicles, candy, games, bounce houses and food trucks. It is described as family-oriented; no numerical age restriction is stated. The event has appeared in free-event listings, but admission terms and live ticket availability could not be independently confirmed. Food-truck purchases would be separate, with prices not posted. The event page offers tickets; whether advance registration is mandatory or a deadline applies is unclear.

Before you go
Schedules, capacity and event arrangements may change. The Gazette has not independently verified real-time ticket availability or obtained same-day confirmations from organizers. Check each linked source before leaving. Sunday, November 1, marks the return to Eastern Standard Time; clocks move back one hour overnight.
Reporting note: Based on organizer and M-NCPPC event listings reviewed October 30, 2026. The Friday-night Magical Night of Wizardry was excluded from this forward-looking guide because it was already underway and its advertised hours conflicted across county materials. Earlier library Halloween activities were listed full, and a Westphalia trunk-or-treat listing found for Parkside referred to 2025, not 2026.
