The Duke Kahanamoku Lagoon: A Hidden Gem Near the Hilton in Waikiki!

Last Updated on January 19, 2024 by Kelly

The Duke Kahanamoku Lagoon is located at the far western end of Waikiki Beach. It’s a saltwater lagoon that has calm water, which is perfect for swimming and paddle boarding. (Especially for kids!) The lagoon is featured right next to the Hilton Hawaiian Village Waikiki Beach Resort, but it’s open to the public. We found it to be the perfect place for our toddler to play in the water.

We spent a lot of time at the lagoon on our recent trip to Hawaii. In this post, we’ll share our tips for visiting the Duke Kahanamoku Lagoon!

About the Duke Kahanamoku Lagoon

The Duke Kahanamoku Lagoon is a man-made lagoon that was built in the 1950s. The lagoon was named after Duke Kahanamoku, who was a major Hawaiian icon. He was a  world-famous surfer, an Olympic swimming champion, a sheriff, and an actor.

The Duke Kahanamoku Lagoon is a saltwater lagoon. It contains a water circulation system that keeps the water clear and clean.

There’s a small island in the middle of the Duke Kahanamoku Lagoon. You’re not supposed to climb on it, but it adds to the charm and beauty of the lagoon. 

The Duke Kahanamoku Lagoon is surrounded by sandy beaches. Depending on when you visit, some areas of the beach may be shaded by the resort’s towers. We were grateful to have a shady spot for our toddler to build sand castles and splash in the water.

The Duke Kahanamoku Lagoon is approximately 5-10 feet deep.

The lagoon is on the Hilton property, but it’s free and open to the public.

What to Pack for a Visit to the Duke Kahanamoku Lagoon

When you visit Hawaii, expect to spend a lot of time at the beaches! Here’s a few things I recommend bringing:

  • Portable Charger: We like this cell phone charger because the cord is embedded. (That’s one less thing to search for in your bag!) This charger will let you charge your phone when you’re out exploring. You don’t want to run out of battery while you’re on the go, because you don’t want to miss a photo opportunity.
  • Waterproof Phone Case: Protect your belongings with a waterproof phone case. 
  • Quick Dry Towel: This is perfect for hikes where you wouldn’t want to pack a bulky towel from the hotel. It’s easy to throw into a beach bag.
  • Flotation Strap: If you’re going to be snorkeling or surfing, and you want to bring a camera or GoPro, you should make sure you have a flotation strap. That way, if you drop your equipment, it won’t sink to the bottom of the ocean.
  • Water Bottle: Stay hydrated while you’re out in the sun! We like this water bottle because it’s insulated and will keep your water cooler for longer. 
  • Vacation Hat: Protect your face from the sun with a wide-brimmed hat. 
  • GoPro: A GoPro will let you take amazing underwater footage. We highly recommend getting one if you want excellent underwater photos and videos!

Summary: Our Visits to the Duke Kahanamoku Lagoon

We really enjoyed spending several afternoons at the Duke Kahanamoku Lagoon. What we liked best about the lagoon was that we were able to swim in the tranquil waters. This is perfect for families with young children, because you don’t have to worry about rogue waves. Part of the beach was shaded during our visit, which provided excellent sun protection while we played in the water. We also really enjoyed having lunch at the nearby food truck! There’s also plenty of Hilton property restaurants located within walking distance. It was the perfect place to spend a relaxing afternoon in Waikiki.
