The Best Attractions on Oahu, Hawaii

Waikiki Beach

Like any metropolitan city, the Waikiki Beach area bustles with activity.

With a sandy beach, shopping, and world-class restaurants only steps away, you don’t need a rental car if you plan to spend your vacation traveling no farther than this iconic stretch of sand.

Most hotels charge a daily fee for in-and-out parking privileges if you choose to rent a vehicle.

(And if you do, we recommend comparing prices and inclusions for different companies through Discover Cars).

The city bus and the Biki Bike program allow travelers to reach many of the closest things to do.

City buses circumnavigate the island, so reaching the north shore or other locations is relatively easy.

Many tours, like whale watching tours during winter, also leave from Waikiki.

For a luxury stay, consider The Royal Hawaiian, a classic hotel with a pink exterior.

Diamond Head State Monument 

From Waikiki Beach, Diamond Head Crater dominates the Honolulu skyline to the southeast.

Visitors can enjoy part of the 475 acres in the Diamond Head State Monument with an easy bus ride.

However, most come to climb to the peak for 360-degree views of the Pacific Ocean, Waikiki, and the surrounding crater.

To beat the heat of the midday sun, plan to hike early, carry bottled water, and forego those flip-flops in place of supportive footwear.

The Diamond Head hike is an interesting one with a switchback trail, a 225-foot tunnel, an old military bunker, and the memorable “stairs of doom.” 

Near the top, the stairs of doom test your fitness level on 99 steep vertical steps to the peak.

Plan one hour to 90 minutes to complete the roundtrip hike, which is widely considered one of the best hikes in Oahu.

Once you complete the hike, reward yourself with a Dole Whip or pineapple smoothie from the food truck in the parking lot.

Keep in mind that as of spring 2022, reservations are now required for visiting Diamond Head.

The Hawaii Capital Historic District 

Honolulu’s historic district showcases notable architecture, providing a mini history lesson.

Standing 18 feet tall, the King Kamehameha Statue memorializes Hawaii’s first king.

Behind him, Ali’iolani Hale, initially built for royalty, is now home to the Hawaii Supreme Court.

More than a million visitors a year come to snorkel at Hanauma Bay.

While you can expect to deal with high crowds during peak season, it’s for good reason!

Hanauma Bay is an excellent place for families and those without much swimming experience. 

With calm waters and shallow depth, snorkelers can see tropical fish without wading too far.

The Hawaii state fish, Humuhumunukunukuāpuaʻa, is commonly spotted in the reef.

Along with 400 other species, you may even be treated to a green sea turtle sighting. 

However, Hanauma Bay doesn’t provide much shelter from the sun.

So, bring an umbrella, wear a rashguard, and ensure you have reef-safe sunscreen (which is required by law in Hawaii).

Ala Moana Beach Park

Not as crowded as Waikiki Beach, Ala Moana Beach Park provides a beach escape with some extras.

The area was once swampland, but the city recently developed it into an artificial beach.

Unless you arrive early, parking is a challenge. It’s best to use public transit to the Ala Moana Mall across the street.

Ho’omaluhia Botanical Garden

Located on the windward side of Oahu, Ho’omaluhia Botanical Garden is simultaneously one of the top attractions in Oahu and also a great place to get (somewhat) away from the crowds in iconic spots like Waikiki Beach.

From the parking lot, a trail leads to Apua Fishpond. Its neighboring pond, Moli’i fishpond, is managed by Kualoa Ranch.

Covering 125 acres, it’s one of Hawaii’s largest fishponds and still raises a variety of fish.

Kailua

One of the larger towns on Oahu, Kailua is one of the most scenic places on the island.

It’s home to what is arguably Oahu’s most scenic beach, Lanikai Beach (more on that in a minute), but it’s also a wonderful place to visit in its own right.

Lanikai Beach

As one of the most stunning beaches in Hawaii, Lanikai Beach offers brilliant white sand and a bright blue sea with the Mokulua Islands in the distance.

The water is calm here compared to the North Shore, so it’s a great place for snorkeling in Oahu.

You can also kayak out to the Mokulua Islands if you want to get active, either independently or with a guided sea kayaking tour.

Valley Of The Temples 

Nestled at the foot of the lush Ko’olau Range, a 240-acre memorial park might seem like an odd place to visit in Oahu.

However, this tranquil place gathers people to honor those from all faiths, including Buddhism and Christianity.

Surrounded by an amphitheater of lush flora, the setting is like something from a fairytale.

Outside, a large reflecting pond provides a sanctuary for hundreds of giant Japanese koi of every color.

If you want to feed them, a little shop to the right of the temple sells carp pellets.

Kaiwa Ridge (Lanikai Pillbox Hike)

The Lanikai Pillbox Hike or Kaiwa Ridge trail provides stunning views of the island’s windward side.

At 1.5 miles roundtrip, expect to spend an hour to 90 minutes to complete the return hike, depending on stops.

With 360-degree views from the ridge, many tackle the climb to enjoy the sunrise and sunset.

Since you’ll be hiking in the dark, take a flashlight and lightweight jacket.

Kualoa Ranch 

Spread across 4000 acres that cover three valleys, the Kualoa Ranch provides fantastic tours for a fun day.

Adventurers can choose from the Jurassic Valley Zipline or an ATV Raptor excursion to Jurassic Valley. 

Although most know Jurassic Park movies were filmed there, on the Hollywood Movie Sites Tour, you’ll discover the filming spots of “Lost,” “Jumanji,” and “50 First Dates.”

The Ranch recommends making a reservation for tours, as popular ones sell out fast.

Allow for two to three hours on most excursions.

However, the Best of Kualoa Experience package combines three tours and lasts seven hours.

Alternatively, the Kualoa Half Day Package lasts 4-1/2 hours and includes two excursions. Both packages include their incredible lunch buffet.

Near the entrance to Kualoa Ranch, the Tropical Farms Macadamia Nuts offers Kona coffee and macadamia nut sampling.

Today, visitors can see some of the preserved fleet, including the USS Missouri Battleship, USS Bowfin Submarine, and USS Arizona National Memorial.

Take to the skies in the Fighter Ace 360 Flight Simulator for the ultimate thrill.

If you can stomach the ride, you’ll experience an aviator’s life with spins, rolls, and aerial somersaults.

A tour of the USS Bowfin is an eye-opener to life on a submarine. The self-guided tour includes the claustrophobic bunks, which are sandwiched above the torpedoes.

While most attractions require a fee, a visit to the USS Arizona National Memorial is complimentary.

After a short boat ride to the memorial, you can read the names of those who lost their lives and see the “tears of Arizona” seeping from the sunken vessel below.

Ewa Forest Reserve

North of Pearl City, the Ewa Forest Reserve allows travelers to experience a dense rainforest.

It’s the polar opposite of the dense concrete jungle of Waikiki, and this mountainous region is not for the faint of heart.

Haleiwa

Planning to visit Oahu’s gorgeous North Shore?

If so, you can’t miss a stop in charming Haleiwa!

Considered the heart of the North Shore, Haleiwa is a great place to stop for lunch or dinner while you’re visiting the North Shore beaches.

The North Shore is less built-up than other parts of Oahu, and Haleiwa is one of the few places with sit-down restaurants, shops, and boutiques.

This is also where you’ll find the rightfully famous Matsumoto Shave Ice

The Dole Plantation 

The Dole Plantation, home to everyone’s favorite pineapples, is undoubtedly one of the most popular places to visit in Oahu.

That being said, it has a very dark history, and the Dole family is part of the reason the Hawaiian Kingdom was forcibly overthrown in the late 19th century.

While today’s version of The Dole Plantation is clearly still a fun place for families to stop en route to the North Shore, it’s best to keep its history in mind when deciding to visit.

One of the highlights of the plantation is a garden maze with 2-1/2 miles of pathways.

After a hot trek through the maze, reward yourself with soft-serve Dole Whip, an island favorite.

Waimea Falls

Just off the Waimea Valley Road, a short walk (0.7 miles) through a botanical garden, leads to a picturesque waterfall.

“Focus on the journey, not the destination” is a fitting quote for this walk.

Laniakea Beach 

Better known as Turtle Beach, Laniakea Beach usually attracts visitors for its turtles and surfing–in other words, for having two of the biggest attractions in Oahu, HI!

The winter months, particularly January, provide the most significant waves for experienced surfers. 

If you’re new to surfing, the calmer waves of summertime might be more suitable.

Due to the wave action and riptides, it’s inadvisable to swim there.

Regards of when you visit, parking can be problematic as tourists come to watch the surfers and seek out turtle sightings.

For the best chance to see turtles, head to the far right of the beach.

Hawaiian Green Sea Turtles lie on the beach during the day, enjoying the midday sun.

It’s unlawful in Hawaii to approach, harass or touch a turtle.

So, volunteers generally stand by to police that onlookers abide by the rules, and roped areas keep tourists at a distance.

Shark’s Cove

Despite the name, Shark’s Cove isn’t known for its sharks but for its snorkeling.

In fact, you won’t find any sharks there!

During the winter, the strong ocean waves might create hazardous conditions.

Unlike Hanauma Bay which charges a fee, you can swim at Sharks Cove for free.

The cove has two sections.

On the right, the depth varies from 15 to 20 feet. To its left, shallow tide pools are ideal for the non-swimmers.

Due to the sharp lava field, it’s advisable to wear water shoes to protect your feet.

Quick Tips for Visiting Oahu, Hawaii

Even though Oahu has more hotels and resorts than the other islands, don’t expect bargain prices when visiting the top attractions in Oahu.

Hotels and food (restaurants and grocery stores) command high prices.

By law, in Honolulu short-term rentals (such as Airbnb and VRBO), must be rented for no less than 90 days.
