1  Ala Moana Regional Park

Ala Moana Regional Park is not just a popular swimming spot – it’s one of the top places for relaxation and outdoor fun. This vast park, shaded by lush trees, is perfect for picnics, barbecues, and even a game of soccer or tennis. Whether you’re looking for a lively atmosphere or a quiet escape, you’ll find the perfect spot here.

The park features a long, wide stretch of fine golden sand – spanning over 2,600 feet (800 m) – and calm, shallow waters. Thanks to an offshore reef, the coastline is protected from large waves, making it an ideal spot for families with kids. You can also go canoeing or stand-up paddleboarding (SUP) here. Oh, and don’t miss the spectacular sunsets!

2  Waikiki Beach

Technically, Waikīkī Beach consists of eight different sections, each with its own charm. One of the favorites is Royal Hawaiian Beach, right in front of the legendary Royal Hawaiian Hotel. You can’t miss it – it’s pink, earning it the nickname “The Pink Palace.”

 

Here, you’ll find a lively atmosphere, with swimmers and sunbathers enjoying the beach to the sound of music. You can rent a surfboard from one of the many surf shops – perfect for beginners – or book a snorkeling tour to encounter vibrant fish and sea turtles up close.

Another popular section is Prince Kuhio Beach, also known as “The Ponds.” This area is protected by concrete walls that calm the waves, creating a peaceful swimming spot. At low tide, the saltwater pools are almost completely cut off from the ocean, making it perfect for non-swimmers. It’s also a great place for a relaxing midday picnic.

3  Hanauma Bay

Hanauma Bay is one of Oahu’s top three beaches and a must-visit snorkeling paradise. With over 400 species of fish, vibrant coral reefs, and frequent visits from sea turtles and seals, it’s a dream for nature lovers.

Due to environmental concerns and damage from excessive visitors and harmful sunscreens, the bay is now a protected nature reserve. To help preserve its beauty, access is limited, and you must make a reservation in advance.

4  Cockroach Cove (Halona Beach Cove)

Don’t let the name scare you away – you’d be missing out on one of Oahu’s most stunning beaches! No one really knows why it’s called Cockroach Cove, but we suspect it’s a clever marketing trick – it’s a name you won’t forget! This breathtaking spot has even appeared in Hollywood films, including Pirates of the Caribbean.

Nestled between dramatic cliffs, this secluded beach boasts crystal-clear water and hidden caves both above and below the surface. As if that weren’t special enough, sea turtles frequently swim here and even rest on the beach.

5  Sandy Beach

Sandy Beach is a top destination for surfers and bodyboarders. Located on Oahu’s south shore, it’s famous for its powerful waves, attracting thrill-seekers from all over. However, don’t underestimate the surf here – locals call it “Neck-Breaker Beach” for a reason. Lifeguards are always on duty and strongly warn inexperienced swimmers to stay out of the water.

While the scenery is stunning, this is not a beach for swimming. The waves can be unpredictable, and the currents are extremely strong. But even if you don’t surf, the dramatic coastline makes for an unforgettable visit.

6  Makapuu Beach

Makapuʻu Beach is another popular spot for bodysurfing. In fact, the first-ever bodysurfing competition was held here in 1953! Today, traditional surfing is restricted – only boards under one meter long without a bottom fin are allowed.

Besides its legendary waves, Makapuʻu is famous for its breathtaking setting. Surrounded by towering cliffs and rugged lava rocks, it offers one of the most picturesque views on the island. Just nearby, you’ll find the iconic Makapuʻu Lighthouse – a favorite spot for hikers and paragliders alike. Even if you don’t swim here, there’s plenty to see. From December to May, the beach becomes a prime whale-watching spot, so bring binoculars!

7  Sunset Beach

Sunset Beach is the perfect place for a swim or a scenic photo session. As the sun dips below the horizon, this spot gets crowded – especially around the famous curved palm tree, a favorite backdrop for stunning sunset shots.

This beach is also home to world-class surfing and stand-up paddleboarding (SUP) competitions. If you’re not into surfing, don’t worry – the crystal-clear water is perfect for snorkeling, with a thriving underwater world just waiting to be explored.

8   Banzai Pipeline

Banzai Pipeline is a beach of contrasts. In the summer, it’s a calm paradise for swimming and snorkeling. But in the winter, it transforms into a surfing mecca, attracting massive crowds eager to witness some of the most legendary waves on the planet.

Pipeline, or simply “Pipe,” is one of the most photographed and filmed surf spots in the world – and also one of the most dangerous. Only the best surfers dare to take on these waves, showing off their incredible tube-riding skills as spectators watch in awe.

9  Laniakea Beach

It’s hard to describe Laniakea Beach because I’ve never been this close to so many sea turtles – both on land and in the water. That’s why it’s often called “Turtle Beach.” The majestic green sea turtles that frequent this shore are what make it so special.

 

If you visit, take the time to observe these incredible creatures in their natural habitat – but remember, touching them is strictly prohibited by law. After an adventurous hike to the nearby Pillbox Hike, Laniakea Beach is the perfect place to cool off and unwind.
