Best places to visit in Oahu, HI

Diamond Head Crater

As Oahu comes into view through the plane window, one sight will stick out like a sore thumb: Diamond Head Crater. Wherever you are on Oahu’s southern coastline, the dormant volcanic crater has a striking presence. Its arid colors soar above the electric blue water, constantly prodding at your sense of adventure.

Diamond Head Crater

One of the top outdoor activities in Oahu is to trek to the top of Diamond Head Crater. From the summit, you’ll experience awe-inspiring vistas of the Pacific Ocean, Waikiki Beach, and the Honolulu skyline.

Even more impressive is the crater itself, formed millions of years ago. The 1.6-mile round-trip hike will raise a sweat, but you’ll be quickly rewarded.

Pearl Harbor National Memorial

On December 7, 1941, hundreds of Japanese fighter planes flew into Pearl Harbor, killing over 2,400 soldiers and civilians. While the harbor still functions as an active naval base, it’s now also home to the Pearl Harbor National Memorial.

Pearl Harbor

Pearl Harbor is a somber and enlightening experience—and not just for American history buffs. While most travelers come to the island for sun, beach, and volcanoes, the stature of Pearl Harbor can’t be ignored. It’s one of the most important things to see in Oahu.

Among other memorable experiences, embark on a tour of the USS Arizona Memorial. The memorial was built over the remains of the ship, where almost a thousand sailors lost their lives.

Waimea Valley

Stretching from mountains to the sea, the Waimea Valley is an extravagant display of lush nature that is quintessential Hawaii. Set back from Oahu’s North Shore, the valley is a mesmerizing way to experience the island’s beauty but also its culture and history.

Waimea Valley

Waimea Valley is home to several historic sites from when Hawaii was still a monarchy. The lush grounds of the park are also an extensive botanical garden. Over 50 themed gardens house native and endangered flora here.

Hanauma Bay Preserve

Waikiki Beach

A cornerstone of Hawaiian history, the Iolani Palace was the official home to King Kalakaua and Queen Liliuokalani, the last monarchy in Hawaii.

A part of the 7-Mile Miracle, a collection of famous surf breaks, Sunset Beach is a playground for those brave enough to venture into the untamed waters. It makes for non-stop action for those watching from the white sand beach.

Lanikai Beach

Oahu is renowned for its turquoise oceans. But the blue waters hit defined at Lanikai Beach. Sitting on the Windward Coast, the beach’s water dazzles with an effervescent energy that constantly tempts you to dive in for a swim.

If you’re up for an adventure, paddle out to the island, or hike the Lanikai Pillbox Trail.

Polynesian Cultural Center

One of the most fascinating places to see in Oahu, the Polynesian Cultural Center offers an invaluable experience and insight into Hawaiian culture. The enthralling attraction is engaging from the start, allowing you to take a hands-on approach to exploring, not just Hawaiian heritage, but a variety of Polynesian cultures.

Polynesian Cultural Center

The 13-acre estate and open-air museum features seven villages that explore local culture in places like Fiji, Tahiti, Samoa, and Aotearoa (New Zealand). At each village, you’ll embark on a variety of hands-on activities focusing on local Polynesian life, from playing authentic games to throwing spears.

Afterward, enjoy a traditional Hawaiian Luau before ending the experience with a grand show called the “Breath of Life.”

Koko Head Crater Trail

Waimea Bay

Another member of the 7 Mile Miracle, Waimea Bay, just south of Ehukai Beach, is home to the Banzai Pipeline. With its own buffet of gigantic waves, Waimea Bay turns into an exhibition for big-wave surfers in the winter months.

Waimea Bay Beach Park

But the rest of the year, Waimea Bay is arguably the most popular beach on Oahu’s North Shore. Its unique aura and distinctive landmarks separate Waimea Bay from the chasing pack.

At Waimea Bay, you can dive off the sea stack, known as The Rock, into the glowing turquoise waters below. From the white sand, gaze upon the church that sits out on the point before enjoying a picnic on the lush lawns.

Laniakea Beach

From the minute you step onto Laniakea Beach, you’ll understand why its name translates to wide sky. The expansive horizon views are enough to distract you from why the spot is also known as Turtle Beach.

Laniakea Beach

On Oahu’s North Shore, Laniakea Beach has residents that are also sunbathers and swimmers but have twice as many limbs. As you lay down your beach towel, you’ll share your day with green sea turtles.

The rocky cove is an excellent opportunity to see turtles up close (not too close). Don’t pass up the opportunity to swim alongside the majestic animals on a snorkel tour.

Kailua Beach

Just north of Lanikai, Kailua Beach is an equally revered beach that proves Oahu is a gift that keeps on giving. The powder-like sand dances between your toes as you walk along the breathtaking shoreline.

Kailua Beach

The 2.5-mile beach is often a preferred choice over Lanikai, thanks to the space available to veg out and enjoy the bright blue ocean. Kailua Beach is also more developed with a variety of amenities, from bathrooms and showers to picnic tables and beach rentals.

Kailua Beach is a great launching point for a SUP adventure, including making your way across the calm Pacific to Mokolii.

Paradise Cove

For a traditional Hawaiian Luau, add a night at Paradise Cove to your Oahu itinerary. At Ko Olina Resort, Paradise Cove is a 12-acre beachfront property with its own semi-private lagoon. But at night the lights shine and the cove comes to life.

Paradise Cove

After entering through an ornate garden, you’ll be presented with either an orchid lei or shell necklace marking the beginning of the exciting experience. You’ll then take part in several fun activities, from spear throwing to coconut tree climbing and lei making.

But the night only gets better as you dine alongside the sunset before a memorable hula show.

Ho’omaluhia Botanical Garden

By now you know: Oahu doesn’t do mediocre and bland—only spectacular. Another way to experience the island’s insane natural diversity is by wandering through Ho’omaluhia Botanical Garden.

Ho'omaluhia Botanical Garden

Surrounding an enormous freshwater lake and with the stunning mountains providing the backdrop, it’s a brilliant experience from the very start. The 400-acre garden offers many spots to enjoy sweeping panoramic views along the miles of walking trails.

You could spend all day exploring the paths at Ho’omaluhia Botanical Garden. However, lake fishing is a popular activity, along with a picnic on the spacious lawns while admiring the native flora.

Ala Moana Beach Park

With its central location and breadth of amenities, it’s no wonder Ala Moana Beach Park is one of Honolulu’s best beaches and one of the city’s most popular spots to hang. With seemingly endless space, you’ll enjoy much of the same views had at Waikiki—without the crowd.

Ala Moana Beach Park

Ala Moana Beach is protected by an off-shore reef allowing for calm, kid-friendly swimming in crystal clear water. While you can relax on the soft white sand, you’ll also have the opportunity to laze on the spacious grass under the swaying palms.

The beach also features several concession stands and even a tennis court. When you’re done, you’ll be steps away from the Ala Moana Shopping Center. The largest open-air mall in the United States, Ala Moana Shopping Center is the perfect place to unload some dinero on all the latest fashions.
