2. Lanikai Beach – Paradise Perfected
Located in the quaint town of Kailua on Oahu’s windward side, Lanikai Beach consistently ranks among the world’s most beautiful beaches. The name “Lanikai” translates to “Heavenly Sea,” and one look at its powdery white sands and crystal-clear turquoise waters will tell you why.
This half-mile stretch of pristine coastline offers calm conditions year-round, ideal for swimming, paddleboarding, and kayaking. The twin Mokulua Islands offshore add to the breathtaking scenery, and early risers can enjoy one of the most spectacular sunrises in Hawaii. Lanikai Beach’s tranquil charm makes it perfect for couples, photographers, and families seeking serenity away from the crowds.
3. Kailua Beach Park – Adventure Meets Relaxation
Just down the road from Lanikai lies Kailua Beach Park, another gem on Oahu’s east side. Known for its consistent trade winds, this beach is a hotspot for windsurfing, kitesurfing, and kayaking. The soft, wide sands also make it ideal for picnics, sunbathing, or a casual game of beach volleyball.
Facilities like restrooms, showers, and picnic tables make it family-friendly, while the nearby town of Kailua offers great dining and shopping options. For travelers who love both relaxation and outdoor adventure, Kailua Beach Park strikes the perfect balance.
4. Sunset Beach—The North Shore’s Crown Jewel
The legendary Sunset Beach on Oahu’s North Shore is a surfer’s paradise and a must-visit for beach lovers. During winter months (November through February), massive waves attract professional surfers from around the world for competitions like the Vans Triple Crown of Surfing.
In summer, the ocean calms, transforming Sunset Beach into a peaceful spot for swimming and snorkeling. Its long stretch of golden sand is also one of the best places to watch Hawaii’s world-famous sunsets—hence the name. Whether you come for the surf or the scenery, Sunset Beach captures the untamed spirit of Oahu.
5. Waimea Bay—Where Surf Legends Are Born
Another North Shore icon, Waimea Bay, is steeped in surfing history. During winter, waves can soar to heights of over 30 feet, drawing elite surfers and thrill-seekers from across the globe. The legendary Eddie Aikau Big Wave Invitational, held only during ideal conditions, takes place right here.
In summer, however, Waimea Bay reveals a completely different side—calm, crystal-clear waters perfect for swimming, cliff jumping, and snorkeling. The nearby Waimea Valley, with its botanical gardens and waterfall, makes for a perfect day trip pairing.
6. Hanauma Bay Nature Preserve – Snorkeler’s Paradise
For those who love exploring underwater worlds, Hanauma Bay Nature Preserve is a dream come true. Formed within a volcanic crater, this marine sanctuary is home to over 400 species of tropical fish and vibrant coral reefs.
Visitors can snorkel among colorful parrotfish, butterflyfish, and even green sea turtles. To preserve the delicate ecosystem, entry is regulated, and visitors must watch an educational video before entering. Arrive early to secure a spot, as the bay has a daily visitor limit. Hanauma Bay’s protected waters and educational focus make it one of Oahu’s most sustainable and enriching attractions.
7. Ala Moana Beach Park – Urban Serenity
Situated between downtown Honolulu and Waikiki, Ala Moana Beach Park offers a peaceful escape within the city. The half-mile-long beach is protected by an offshore reef, creating calm, shallow waters perfect for swimming and paddleboarding.
The park’s wide grassy areas, walking trails, and picnic spots make it ideal for families and locals seeking a relaxing day outdoors. On weekends, you’ll find residents barbecuing, jogging, or practicing yoga by the water. With free parking and proximity to the Ala Moana Center shopping mall, this beach combines convenience with tranquility.
8. Makapu’u Beach – Scenic and Rugged
Located on Oahu’s southeastern tip, Makapu’u Beach offers breathtaking natural beauty surrounded by volcanic cliffs and the famous Makapu’u Lighthouse. The beach is known for its powerful waves, making it a favorite among experienced bodyboarders and bodysurfers.
While swimming can be challenging due to strong currents, visitors can enjoy beach walks, photography, or a hike up to the lighthouse for panoramic views of the Pacific and nearby islets. The combination of dramatic landscapes and ocean energy makes Makapu’u one of the most photogenic spots on the island.
9. Ko Olina Lagoons – Luxury and Leisure Combined
On Oahu’s leeward (west) coast, Ko Olina offers a completely different vibe—calm, upscale, and family-friendly. This resort area features four man-made lagoons with crystal-clear waters protected by breakwaters, ensuring safe swimming year-round.
Each lagoon has sandy shores and clear paths connecting them, making it easy to explore. Nearby luxury resorts like Aulani, A Disney Resort & Spa, and the Four Seasons Resort Oahu enhance the experience with world-class dining and amenities. Ko Olina is perfect for travelers seeking comfort, calm waters, and postcard-perfect views.
10. Shark’s Cove – A Snorkeling Gem
Despite its intimidating name, Shark’s Cove is one of Oahu’s best snorkeling and diving spots, especially in the summer when the waters are calm. Located in the Pupukea Marine Life Conservation District on the North Shore, it features lava rock formations that create natural tide pools teeming with marine life.
Snorkelers can expect to see schools of colorful fish, sea urchins, and occasionally sea turtles. The rocky terrain can be tricky, so water shoes are recommended. Nearby food trucks offer delicious local bites, making Shark’s Cove an excellent stop for a half-day adventure.
