7 Completely Free Things to Do on Oahu with Kids

You’ve probably heard that Hawaii vacations are expensive. And sure, flights and hotels can add up quickly. But here’s what most travel guides won’t tell you: some of the best free things to do on Oahu with kids don’t cost a single dollar.

As a Hawaii travel expert who’s spent years researching and visiting Oahu, I’ve discovered that you can experience authentic Hawaiian culture, stunning natural beauty, and unforgettable family adventures without breaking the bank. I’ve helped hundreds of families plan budget-friendly Hawaii vacations, and the biggest misconception I encounter is that everything in Hawaii comes with a hefty price tag.

The truth? There are tons of free things to do in Oahu that rival any paid attraction. This guide shares five completely free activities—zero entrance fees, no parking charges—plus three bonus ideas to help you create an incredible trip to Hawaii on any budget.

Activity #2: Baby Makapuʻu Tide Pools

Here’s one of those spots that locals love but doesn’t always make it into the guidebooks. Baby Makapuʻu offers protected tide pools where your kids can swim and explore marine life—but it comes with some important safety considerations.

What Makes It Special

Located near the Sea Life Park exit on the east side of Oahu, Baby Makapuʻu features natural lava rock pools that fill with ocean water. When conditions are right, these pools create a protected swimming area where kids can:

• Spot sea creatures like small fish, crabs, and sea urchins
• Swim in calm, protected water (when tide and surf conditions cooperate)
• Explore tide pools at different depths
• Visit Dragon’s Breath blowhole nearby

Why Your Kids Will Love It

It’s like a natural aquarium. Kids love the adventure of climbing down to the pools and discovering what’s living in them. The protected nature of the pools (when conditions are safe) makes it less intimidating than open ocean swimming.

Critical Safety Information

Read this carefully: Baby Makapuʻu can be extremely dangerous. Rogue waves and surges have injured visitors here. You need to:

• Check tide charts and visit only at low tide
• Watch ocean conditions before descending
• Never turn your back on the ocean
• Keep kids within arm’s reach at all times
• Wear water shoes (sea urchins are common)
• Skip it if surf is high or conditions look questionable

The access requires an intermediate-level descent on loose lava rock. It’s steep and can be slippery. This is not suitable for toddlers or anyone with mobility concerns.

Insider Tips

Best time to visit: Low tide during calm summer months. Check tide charts before you go.

What to bring:

• Water shoes (non-negotiable—sea urchins hurt)
• Towels and dry clothes
• First aid kit
• Reef-safe sunscreen
• Snacks and water

Dragon’s Breath blowhole: After visiting the tide pools, walk over to see this natural blowhole. It’s impressive when waves are moderate (but keep a safe distance).

Activity #4: Kuhio Beach Hula Show

Every Friday night, Kuhio Beach in Waikiki comes alive with authentic Hawaiian music and hula. It’s one of the best free things to do in Oahu for families, and it offers a way to experience traditional Hawaiian culture in a beautiful beachfront setting.

What Makes It Special

This isn’t a resort show—it’s a community tradition. The Kuhio Beach Hula Show features local hula schools (hālau) performing traditional and contemporary hula, accompanied by live Hawaiian music. The show opens with a traditional conch shell blowing (pu kani), which is a powerful cultural moment.

Schedule & Location

When: Saturdays, 6:30-7:30 PM (weather permitting)
Where: Kuhio Beach Hula Mound, Waikiki

The timing is perfect—you’ll catch the sunset over Waikiki Beach while watching the performance.

Why Your Kids Will Love It

The combination of music, dance, and beachfront atmosphere keeps kids engaged. The performances are family-friendly, and the casual beach setting means kids can sit on blankets, move around a bit, and enjoy the experience without formal theater constraints.

Insider Tips

Arrive early: Get there 30-45 minutes before the show starts to claim a good spot. Bring beach blankets or low beach chairs.

Best viewing spots: Front and center at the hula mound, but anywhere with a clear view works. Some families prefer sitting slightly back where kids have more room.

What to bring:

• Beach blanket or low chairs

• Light jacket (it can get breezy after sunset)
• Camera

Cultural respect: This is a cultural performance, not entertainment. Watch respectfully, don’t talk during performances, and hold applause until dances are complete.

Activity #5: Makapuʻu Point Lighthouse Trail

What Makes It Special

This 2.5-mile round-trip trail is one of the few fully paved hikes in Hawaii, making it accessible for strollers, wheelchairs, and families with young kids. But don’t let the easy access fool you—the views are world-class.

You’ll see:

• Koko Head crater
• Offshore islets including Manana (Rabbit Island) and Kaohikaipu
• Sea Life Park from above
• Whales during winter months (November-May)
• WWII pillboxes (ruins you can explore)

Why Your Kids Will Love It

The paved path makes it easy for kids to walk or bike. During whale watching season (winter months), you might spot humpback whales breaching offshore—bring binoculars. The WWII pillboxes add an element of exploration and history that older kids find fascinating.

1. Cooler temperatures (this trail is fully exposed with zero shade)
