It runs as a two-hour drop-in window in daylight on the afternoon before Halloween, so families can go at their own pace. The trails are natural surfaces with roots, rocks and uneven ground — wear flat, closed-toe shoes, and expect a stroller to struggle. Registration is required. ## Similar picks in Washington, DC - [Flights & Frights: Trick or Treat at the Museum](https://grassyknees.com/washington-dc/activities/flights-and-frights-trick-or-treat-at-the-museum--listing-62cec16c636dd76825db1f7c) — Sat, Oct 24 · 5:30 PM – 7:30 PM · College Park Aviation Museum · All ages · From $5 · checked Oct 16.
