Try all the Hawaiian food
What’s on the menu in Oahu, Hawaii? Things to do include trying Garlic Shrimp, Poke Bowls, Huli-Huli Chicken and Dole Whip. Hawaiian food combines migrant influences with local ingredients, and this can be seen – and sampled – in the Portuguese malasadas or Japanese shave ice that are popular sweet treats.
We are food tour fanatics and highly recommend joining this foodie bike tour where you’ll see the sights of Honolulu and taste the island’s top dishes we mention below.
A Hawaiian Poke Bowl consists of raw, diced fish alongside other ingredients like rice and vegetables. Delectable sauces are often served alongside. This delicious and nutritious dish is a must-try when in Oahu.
Huli-Huli Chicken is a grilled poultry dish served with the signature Huli-Huli sauce. The sauce is mainly sweet, typically containing pineapple, brown sugar and ginger, but a salty, savory note is also often present due to the addition of soy sauce, black pepper and garlic.
There are plenty of shave ice shops across Oahu, yet this seemingly Hawaiian dessert originated in Japan. It comprises vanilla ice cream topped with various flavors of shaved ice. Apparently it became popular after Japanese immigrants came to work in the pineapple plantations and prepared it as a refreshing and cooling snack. The original and the best is found at Matsumoto Shave Ice in Haleiwa on the North Shore.
According to legend, the best Hawaiian shrimp comes from Giovanni’s Shrimp Truck, when they converted a 1953 bread truck in 1993. Now, the company owns the land they park on and added a pavilion in 2010. Trying Giovanni’s Garlic Shrimp is a must when in Oahu.
The Dole Food Company devised this soft serve dessert in the mid 1980s. The original is pineapple, but other fruit flavors include peach, lime, strawberry, orange, lemon, raspberry and watermelon. It’s one to try on Oahu, where pineapple plantations abound. You can try huge serves at the Dole Plantation where you can also visit the gardens and take a train ride through the grounds.
A malasada originates from Portugal, and is basically a donut with no hole. A great, golden malasada is light and fluffy within. Leonard’s Bakery began producing them in 1953, to celebrate Shrove Tuesday, and the establishment is still Oahu’s original malasada bakery.
Get back to nature
Nature experiences on the island are also some of the top things to do in Oahu. Active types can trek to waterfalls or go diving, or you can sit back and relax while looking for green sea turtles or humpback whales. There’s also lots of underwater life to look out for while snorkeling.
View the turtles at Laniakea Beach
Laniakea Beach is famous for its visiting Green Sea Turtles. They come here year-round, at all times of day, though there is slightly more chance of seeing them basking in the sun during summer – as well as when the water is calmer. Make sure to keep your distance and be respectful near these ancient sea creatures.
Spot whales and dolphins
It’s not only humans who are attracted to Hawaii – Humpback Whales from the North Pacific return from December to May each year to breed, give birth and raise their calves. They can be seen from the south coast of Oahu. Taking an organized boat trip can improve your chances of seeing dolphins as well as whales. We saw six whales and tens of dolphins on our boat tour and it was one of the highlights of our trip. The boat departs from outside the Hilton Hawaiian Village hotel >> more details
Chase amazing waterfalls
Oahu is an island that’s seriously abundant in waterfalls. The walks and hikes to get to them range from the very easy route to Manoa Falls to the seven-mile trek to reach Laie Falls. At Maunawili Falls, there’s a deep, freshwater swimming pool to reward your efforts. Other notable waterfalls include Waimea Falls, the Jackass Ginger Pools, Likeke Falls, Koloa Gulch and Waimano Falls.
Go tropical snorkeling and diving
There are opportunities to dive and snorkel all over Oahu, especially during summer when the waters are calmer, with all manner of sea life to look out for. Rocky Shark’s Cove bay on the North Shore is a top spot – one of the world’s best locations. Other snorkeling beaches include Waimea Bay and Lanikai Beach. If you want to use your trip to Oahu to learn to scuba dive, it’s a great safe place to start. Tropical waters are full of amazing sea life and your Divemaster will make sure you are safe.
Brave the shark dive!
Ever wanted to get up close and personal with a shark? It’s not our cup of tea but plenty of people love the adrenaline rush of being underwater and close to the predators of the sea. Join a shark dive and you can have this experience safely, just off the coast of Oahu. You can watch from the boat or jump into a secure cage in the sea where you’ll be surrounded by fish, dolphins and sharks. This exciting activity takes place on the North Shore but you can arrange a transfer from Waikiki too >> more information
Head to the beach
Beaches don’t come more pristine than this! The best beaches in Oahu have white sandy bays with clear, tropical blue water. Some are great for experienced surfers, while others are more suited to swimming, bodyboarding, kayaking and snorkeling. Or, if you’re more adventurous – windsurfing, diving or sailing.
The fine white sands of Lanikai beach can be found near Kailua on the windward side of Oahu, and the beach has an offshore reef that ensures safe swimming. Two tiny islands with bird sanctuaries are under a mile from the shore, and can easily be reached by kayak. Snorkeling, windsurfing and sailing are also popular pastimes.
Kailua Beach is just a mile from Lanikai Beach, boasting three miles of clear, calm water and pale sands. Visitors can enjoy using the picnic areas or volleyball court, or perhaps learn how to windsurf.
Sunset beach is located on Oahu’s North Shore. Calm, clear azure waters lap the shore in summer, while in winter the rolling waves are a big draw for experienced surfers – and it’s best left to the experts when such conditions exist. Watching them, and the huge waves, is great fun.
Of all the top 5 beaches in Oahu, Waikiki is the most famous worldwide. At two miles long, the white sands consist of sections connected by a boardwalk. Conditions suit surfers and swimmers all year round, while other popular activities include canoeing, stand-up paddle boarding and beach volleyball.
Like Sunset Beach, Waimea Bay is on the North Shore, and is also renowned for incredible wave action during winter. In summer, calmer waters make it a great spot for snorkeling, diving and swimming.
Waimanalo Bay’s soft sand beach is almost five miles long, and thus one of Oahu’s largest. This scenic Hawaiian beach is good for sunbathing, bodyboarding, walking and fishing, although rougher waters make it less suitable for swimming.
Watch the sunset
The Hawaiian islands are one of the world’s best places to watch the sun set. Choose between a range of pristine beaches with calm, clear waters or rolling surf, and settle down to witness nightfall in one of the world’s most beautiful and tropical settings.
Ala Moana Beach Park
Seeing the sun sink into the horizon at Ala Moana Beach park can be the perfect end to an idyllic Hawaiian day. The beach park is family friendly, with picnic tables, tennis courts, shady trees and lots of boats to see.
Sunset beach on Oahu’s North Shore is known for two things – big waves being one. The second is self-explanatory. Sunset here is unmissable, not least because of the rolling surf and those who head back into the water for one last ride before darkness descends.
The calm, clear waters of palm-fringed Ko Olina Lagoons are popular at all times of the day – but especially at sunrise and sunset. This area is great for swimming and snorkeling in safety during daytime too.
Duke’s Bar in Waikiki
Duke’s bar in Waikiki is famed for its beachfront position as well as steak and seafood grills, cocktails and a tiki vibe. Its outdoor deck is a great spot in which to sit with a sundowner as night sets over Waikiki beach.
Why not book one of the romantic sunset cruises in Oahu for a celebration or as a grand finale to your vacation? Setting sail as the days draws to a close is a very popular way to see the sun go down in Hawaii. A typical cruise might include dinner, drinks, music and hula dancing. But you can also organize a more intimate and exclusive experience where you can enjoy
