Halloween in Hawaii is bigger than most visitors expect. **Waikīkī becomes one big costume party** the weekend before, the malls host massive family trick-or-treat events, and the surf clubs throw the rowdiest Halloween nights you'll find anywhere. October 31, every year. Plus the Friday/Saturday before. ## Family + kids events ### Mall trick-or-treat - **Ala Moana Center** — biggest in Hawaii. Costumed kids hit 100+ stores 3-7pm on October 31.

Always weather-dependent. Free with park admission ($30). ### Pumpkin patches - **Aloun Farms (Oʻahu)** — biggest patch in Hawaii. October weekends. - **Waimanalo Country Farm** — smaller, more local feel. ## Adult / nightlife ### Waikīkī The Friday and Saturday before Halloween, Kalākaua Avenue becomes a costume parade. Bars + clubs: - **RumFire (Sheraton)** — annual Halloween bash, costume contest - **The Modern Honolulu** — pool party, DJs - **Sky Waikīkī** — rooftop, big costume contest - **Kelley O'Neil's** — Irish pub vibe, all-night party ### Off the strip - **Republik (Honolulu)** — biggest concert venue Halloween shows - **The Wonder Lounge** — gay-friendly costume night - **Surfer Bar (North Shore)** — local vibe, Halloween bonfire ## Costume tips for Hawaii - It's **80°F at night**. Cancel the wool sweater + jacket combo. - Costumes get sweat-soaked fast. Bring a change. - Some Waikīkī clubs have dress codes that override costumes (no flip-flops, etc.). ## Things specific to Hawaii - **Night marchers** are real Hawaiian folklore — ghost warriors who walk certain trails at night. Locals don't joke about them. If someone tells you to stay off a specific trail Halloween night, take them seriously. - **Pele**, the volcano goddess, is occasionally said to appear at Halloween in various forms. Respect the legends. ## See current Hawaii events - [Hawaiian Holidays Calendar 2026 →](/blog/hawaiian-holidays-calendar-2026) - [Best Free Things to Do in Honolulu →](/blog/free-things-to-do-in-honolulu) - [Browse all events →](/events)
