Frequently Asked Questions

How do we attend Día de los Muertos events in Portsmouth respectfully?

Come as a guest, not a spectator: it's a celebration honoring deceased loved ones, not spooky-adjacent entertainment. Participate where invited, processions, community ofrendas, craft tables, ask before photographing people or altars, and buy from the vendors and artists who anchor the event. Learn the basics beforehand, marigolds, ofrendas, calaveras, and skip Halloween costumes; this holiday stands on its own.

How do we find free community Halloween events in Portsmouth?

Check the sources that don't advertise: library calendars, parks and recreation listings, neighborhood association pages, school and church flyers, and city event roundups, most published in late September. Trunk-or-treats, costume parades, pumpkin-carving meetups, and downtown merchant trick-or-treats are almost always free. Build a season list in one sitting in early October, because the good ones happen once and don't repeat.

Can we bring dogs to fall festivals and outdoor Halloween events in Portsmouth?

Check each event, since policies split evenly: many street festivals and brewery events welcome leashed dogs, while farms, food-focused markets, and anything with livestock usually prohibit them. If dogs are welcome, bring water and a mat, skip the costume unless your dog genuinely tolerates it, and be honest about crowd stress. Some events run dedicated dog costume parades, the best of both worlds.
