What’s your idea of a memorable birthday? If it involves explosive volcano hikes, technicolor sunsets, multiple mai tais, and moonlit stargazing experiences – not to mention eating your own bodyweight in coconut cake – you’ve come to the right place. There are stacks of great things to do in Oahu and Honolulu for your birthday and we’ve rounded up some of the very best to help you get the party started, including:

  • Traditional luau shows
  • Haupia cake
  • Honolulu Zoo
  • Cocktails at sunset
  • Oahu stargazing

  • Catamaran sailing tours
  • Honolulu nightlife

Cake, Glorious Cake

Traditional Hawaiian haupia cake made with coconut and purple sweet potato

A birthday without a cake is no birthday at all, so start your special day the right way with Oahu’s finest: the delectable treat that is haupia. Admittedly more pudding than cake in its traditional form, it’s kind of like a coconut jelly. Combined with the sweet flavors of Oahu’s North Shore pineapples, however, it’s like pure sunshine in your mouth, the closest it’s possible to get to a genuine pina colada in cake form. But hey, it’s your birthday, so why stop there? Follow up with great slabs of guava chiffon cake and chocolate chantilly cake as the day progresses. Yum.

Set Sail Aboard a Catamaran

For many, the whole point of a birthday is putting your feet up and behaving like some sort of A-list celeb while everyone else does the heavy lifting. If that sounds appealing, a catamaran tour of Oahu’s Insta-perfect coastline is likely to be just the birthday treat for you. Cruising past soaring, jungle-clad mountains and over submerged volcanic craters, you’ll be well positioned to spot some of the local wildlife: playful dolphins, flying fish, maybe even the occasional migrating whale! Pull out all the stops on your special day with a decadent bells-and-whistles experience that includes lunch on deck, snorkeling stops, and chilled glasses of bubbly.

Say it with Flowers

There are a whopping 52 themed zones in the 1,875-acre oasis that is the Waimea Valley botanical gardens. Here’s where you can ogle, snap and sniff some 5,000 tropical and subtropical plants, including endangered species and native Hawaiian beauties like loulou palms and the delicate white Koki'o ke'oke'o flower – the world’s only scented hibiscus. Follow paved trails through the themed gardens, breathing in the fresh scents of flora from Fiji, Guam, the Americas and beyond. The shady groves and cooler climate in this lush botanical paradise make it a great place to wander while the tropical sun is at its most punishing. But if the heat does get too much, you can always cool off with a dip in the pools beneath the mighty Waimea Falls, the focal point of this huge natural park.

Hawaii’s Hottest Hike

Hawaii ain’t short of a fine hiking opportunity or two. But if you only do one, make it Diamond Head, the iconic volcanic crater at the eastern end of Waikiki Beach. It’s a relatively unchallenging walk that takes you 760 feet up to the crater’s forested rim, affording splendid views of Honolulu, Waikiki Beach and beyond. You need to book a slot to be permitted entry, and early risers are likely to enjoy the best of the climb, thanks to cooler temperatures, smaller crowds, and those glorious Hawaiian sunrise skies – gates open at 6AM. Shuttle trips to/from the trail from any Waikiki hotel are included with a Go City Oahu attraction pass, which can save you money when taking in several tours, attractions and activities on the island. Find out more about the Oahu pass here. 

Honolulu Zoo

First opened way back in 1877 to house King David Kalakaua’s burgeoning bird collection, Honolulu Zoo is now home to some 1,000+ cute critters. Pop by on your birthday to say ‘aloha’ to some of the residents. We’re talking vibrant Fiji banded iguanas, ferociously cute fennec foxes, and chatty golden lion tamarins, as well as indigenous species including Hawaiian hawks, colorful Kamehameha butterflies and the nene (or Hawaiian goose), official state bird of Hawaii. It’s a great Oahu birthday day out for kids and adults alike. You can even host a kids’ party at the zoo; find out more here.

Birthday Sundowners!

Cocktails overlooking the bay at Waikiki, Oahu

Oahu sunsets are among the best in the world, a surefire way to fill your birthday Insta feed with #humblebrag shots of burnished-copper and rust-red skies. Complete the effect with a colorful cocktail – blue Hawaiian or mai tai, with its citrusy blend of lime, sweet orgeat syrup, orange curaçao and mule’s kick of rum for the win. The legendary Duke’s on Waikiki Beach is the connoisseur's choice for the best views of Diamond Head and the bay, but there are countless fun tiki bars down here for birthday boys and girls to choose from.

Take in a Traditional Luau

Another popular birthday activity in Oahu is the classic Polynesian luau. Some of the best and most authentic of these are small, family-run affairs, where the aloha spirit is abundant and you’re invited to take an active role in the colorful traditions: dancing, dining and dressing up. The Hawaii mega resorts offer slicker, bigger-budget takes on the luau, promising lavish banquets, fireworks, bombastic music and more, and you’ll find some of these included with the Go City Oahu attractions pass.

Hit the Honolulu Pubs and Clubs

Club DJ in action

Honolulu positively heaves with great places to party, from rocking rooftop joints like Mai Tai’s atop the Ala Moana Mall to classy cocktails at Lewers Lounge in the upscale Halekulani Hotel. Get your boogie on at some of the city’s hottest nightclubs, even if you should be old enough to know better! Follow the hip crowd to Chinatown's lively Manifest, get down to superstar DJ-spun tunes on Nextdoor’s massive dance floors, or dance yourself dizzy at Sky Waikiki, atop the towering Waikiki Business Plaza.

Birthday Stargazing

For something a little more… sedate, spend your birthday evening on Oahu contemplating life, the universe and everything as you stare up at the tapestry of stars that hangs high above the islands. Some of the best spots for this particular birthday treat include the iconic Halona Blowhole, Ka’ena Point, and the North Shore’s stunning surf beaches. Anywhere, in other words, where you’re some way from the city lights. Go it alone or join one of the island’s regular guided stargazing sessions. Or, if you want to go really stratospheric for your Hawaiian birthday experience, hop over to Big Island where the Mauna Kea mountain has a dedicated astronomy center with stargazing telescopes about halfway up, and tours all the way to the top, for unparalleled Milky Way views, can be arranged.

Things to do in Oahu When It's Hot Outside

Hawaii is hot in every sense of the word: its warm climate makes it pleasant to visit year-round, which in turn makes it one of the planet’s most popular tourist destinations, pulling in around eight million visitors every year. The majority of Hawaii sunseekers (around five million, give or take) wind up on the island of Oahu, home to some of the state’s biggest attractions – Pearl Harbor, Waikiki Beach, Honolulu and the Diamond Head volcano, to name just a few. It goes without saying then that there’s plenty of fun to be had in the sun here. After all, no-one goes to Hawaii for its skiing opportunities, right? But with summer temperatures that average way up in the high 80s, you’ll likely want to pencil in a few slightly cooler activities (as well as covering yourself top to toe in factor 50, natch). Here, then, are a few ideas for things to do in Oahu and Honolulu when it’s hot outside, including: Beaches! Snorkeling! Catamarans! Pineapples! Shave ice! And more! Keep Your Cool on the Beach You’ll want to pack plenty of beach bag essentials for your day at Waikiki, Hanauma Bay, the North Shore and, well, whichever of Oahu’s stunning tropical beaches tickle your fancy. We’re talking UV sunglasses, great big floppy sun hats and gallons of bottled water as a bare minimum. You may want to add a parasol or tent for use in some of the more exposed bays, though you’ll also find plenty available to rent in the main tourist areas. Beaches like Lanikai and and Kailua on Oahu’s windward side (the east coast) tend to offer more natural shade, in the form of palm trees. Top-tip: before slinging your towel down underneath, check carefully for the very real and present danger of ripe coconuts up above. You’ll be cooling off in A&E if one of those beauties drops on your nut! Waikiki Beach is of course the most popular of Oahu’s beaches, and opportunities to cool off on snorkeling trips here abound. Cruise out onto the beautiful clear blue waters and come face to face with all manner of tropical marine life. You’re all but guaranteed to meet green sea turtles at the aptly named Waikiki Turtle Canyon. Hanauma Bay is where it’s at for some of Oahu's most spectacular sealife selfie opportunities. Vibrant yellow tangs and flamboyant spinner dolphins are just two of the cute critters you might spot on snorkeling excursions to the thriving coral reef that lies in the cone of this long-extinct volcano. Hit up the pristine sands of Lanikai Beach for more of the same (but with added palm cover), and crescent-shaped Kailua Beach (pictured above), where balmy trade winds encourage other watery pursuits including kitesurfing and kayaking. Oahu’s Hottest Tours If you simply can’t bear to spend all day lounging in the shade of a coconut palm, moving only to top up your rum-laced Mai Tai cocktail, there are plenty of island tours you can take around Oahu and Honolulu on hot days instead. Here, after all, is an opportunity to see this beautiful volcanic paradise from the lush cool confines of an air-conditioned coach. Try a trip to the Dole plantation on the North Shore. Sampling the sweet flesh of their world-famous pineapples under the hot Hawaiian sun is one that’s worth disembarking the refrigerated coach for, and no mistake! You could also take a tour of Oahu’s hidden gems, including tranquil temples, shaded Japanese gardens, and the cooling spray of epic blowholes like Halona. Or immerse yourself in rainforests and visit the 150-foot Manoa waterfalls, passing through jungle scenery used in The Hunger Games movie series. You can book tours including all of the above (and more) with an Oahu pass from Go City, which can save you up to 50% on top attractions, tours and activities on Oahu. Find out more and bag your Oahu pass here. Ice Cold in Oahu Hawaii is arguably as famous for its shave ice as its beaches, volcanoes and hula skirts. Find out what all the fuss is about at any one of dozens of purveyors of this frozen treat across the island. Shave ice is exactly what it sounds like: tiny shavings of ice liberally doused in lashings of fruit syrup, and boy is it refreshing on a hot day. Get yours from North Shore shave ice stalwart Matsumoto’s. A fixture on Oahu since the early 1950s, its natural lychee, passion fruit and yuzu flavorings are some of the best in Hawaii. Other local favorites include Ululani’s and Shimazu – for all the ice-cold refreshment but without the half-hour lines. Top tip: it’s ‘shave ice’ not ‘shaved ice’, so be sure to sidestep any vendor that didn’t get the name right on their signage. Life on the Ocean Wave Feel the sea breeze on your skin aboard a catamaran or luxury yacht as you tour the Oahu coastline in style. This is a fine (and crucially effortless) way of seeing a bit more of the island and perhaps even ogling the odd humpback whale, flying fish or green sea turtle on your travels. Don your floppiest sun hat, slather on the sunscreen and sip a glass of prosecco on deck-o as you cruise past jungle-clad mountains and over the coral-rich depths of Oahu’s submerged volcanic cones. Take your pick from straightforward catamaran excursions to decadent day trips that include lunch, snorkeling, and bottomless bubbly. You can access a variety of superb sea-faring options with the Go Oahu pass. Oahu’s Coolest Hikes Ok ok, so hiking may not be the first activity that springs to mind when it’s hot out in Oahu, but bear with us. The botanical gardens at Waimea Valley are a 1,875-acre oasis of lush plantlife and great fronds of greenery. Shady groves and a cooler climate make the gardens ideal for strolling, even when the tropical sun is at its most punishing. Meander gently through some of the park’s 52 themed zones, where towering cacti and fresh-scented hibiscus flourish, and where the picture-perfect Waimea Falls provide ample opportunity for cooling off should the heat get too much. Alternatively, hop across to Big Island, home of Mauna Kea, the highest peak in Hawaii. Hikes to the summit commence from the visitor center, 9,200 feet up, where you’re all but guaranteed freezing temperatures and possibly even snow. But be warned that this 12-mile round-hike is not for the faint of heart, with challenging terrain and the threat of altitude sickness the price of evading the Hawaii heat way up here.
