10 Fun Things to Do on Oʻahu This Halloween [October 2025]

Honolulu’s haunted houses go all out for Halloween, with months of planning, auditions and eerie sets designed to deliver serious scares! Age restrictions are in place due to the frightening content, strong language and intensity, so check the limits before you book.

Haunted Plantation transforms the historic Hawaiʻi Plantation Village into a terror zone. Trial of Fears brings frights to a pop-up venue in Ward Village, while Theatre of Terrors: Murder Hotel blends horror with mystery as guests race to solve clues before the killer strikes.

For those who love to dress up, Honolulu hosts delightful costume contests filled with creativity, excitement and prizes. One of the best is the Keiki Halloween Costume Contest at Royal Hawaiian Center (26 Oct), where kids showcase their most imaginative (and cutest) looks.

Across Oʻahu, family-friendly events at malls, parks and fall festivals feature their own costume contests, making it easy to join the fun wherever you are. Even if you’re not competing, the festive atmosphere, unique costumes and lively crowds make these gatherings a joy to watch.

If you’re visiting during Halloween, Oʻahu makes it easy for families to join in the trick-or-treating fun. Instead of door-knocking in neighborhoods like Kāhala, Mānoa, ʻĀina Haina and Hawaiʻi Kai, take part in one of the island’s many organized trick-or-treat events created with visitors in mind.

Shopping centers including Ala Moana Center, Pearlridge Center and Royal Hawaiian Center host themed celebrations where kids can fill their candy bags, show off costumes and soak up the Halloween spirit. Some even feature games and free goodie bags for the little ghosts and goblins!

Honolulu sets the stage for spooky fun in October with concerts and performances that bring Halloween to life through music and theater. From eerie instrumentals to movie-inspired shows, local venues transform the season into a hauntingly good time.

Catch the cult-classic Little Shop of Horrors, the ghostly Hapa Halloween: Mysteries of Hawaiʻi in Concert, or the elegant Candlelight: Halloween Classics Concert. Film fans alike will love Harry Potter and the Half-Blood Prince™ in Concert, blending cinematic magic with a live symphony.

Oʻahu’s nightlife takes on a spooky glow each October, with pop-up bars mixing eerie energy and creative cocktails across the island. Expect themed décor, costumed bartenders, haunting playlists and one-of-a-kind drinks that bring Halloween to life after dark.

Make the rounds at Spooky Bar at Aloha Mamacita, Nightmare Bar at Pearlridge Center and Ghost Bar at Ala Moana Center. Whether you’re sipping a smoky elixir or showing off your costume, these pop-ups serve up wicked fun for adults celebrating Halloween island-style.

Autumn, known as Fall in the United States, means one thing — pumpkin season. As Halloween nears, Oʻahu’s restaurants, cafés and bars embrace the flavor with limited-edition bites and beverages. For pumpkin lovers, it’s the most delicious time of year.

Treat yourself to a Pumpkin Pie Blizzard® at Dairy Queen in Hilton Hawaiian Village or a slice of Pumpkin Pecan or Pumpkin Cheesecake at The Cheesecake Factory in Waikīkī. Sip a Pumpkin Spice Aperol Spritz at Noi Thai Cuisine or start your day with Pumpkin Spice Pancakes at IHOP.

If you’re after Halloween fun that’s anything but ordinary, Oʻahu has plenty of unexpected ways to celebrate. From themed dining nights and classic horror flicks to mystical workshops and quirky community events, there’s something intriguing happening every week this October.

Highlights include Wicked Wednesdays at DECK. Waikiki, where guests channeling the Wednesday series, or simply dressed in black, receive 20% off their bill. Film fans can enjoy cult favorites like Poltergeist on the big screen, while singles can mingle at Halloween-themed speed dating nights.

On Halloween night on Oʻahu, Waikīkī’s main strip — Kalākaua Avenue — transforms into an open-air costume party! Thousands of dressed up revelers take over the sidewalks, showing off their creativity as they drift between bars, restaurants and late-night hangouts.

Many partygoers are on their way to and from ticketed Halloween events happening across the island. If you’re planning to join the fun, explore Oʻahu’s Halloween nightlife lineup early and secure your spot — these organized spooky experiences sells out fast!
