Family itinerary

Choose Quincy or Graeagle for Halloween evening, rather than assuming you can complete both merchant routes before closing. October mountain weather can bring ice; give the Pumpkin Patch Express its own day.

Safety and accessibility

Do not assume a scheduled event is free unless the source states it. Verify age guidance for scary attractions and reservation requirements for trains or ticketed experiences. Wear warm clothes on mountain and coastal outings, and use marked crossings during downtown candy walks.
