Hang on tight because we are going to cover the best adventurous things to do on Kauai with kids with an appetite for off-the-beaten-path fun!

Getting Around Kauai

First, though, let’s chat about the best ways to get around the island with a family. Kauai is quite small, about 25 miles wide and 33 miles long.

It essentially has one major road that winds around the coast of the island. The exception is the northwest part of the Napali Coastline which prohibits the construction of roads.

Private shuttles, a public bus system, taxis, ride-sharing services like Uber/Lyft, and self-drive car rentals are all of the transportation options available on Kauai.

Each option has its pros and cons. To fully maximize your precious Kauai vacation time and seek out the best family adventure activities you will want to rent a car. The car rental process can be a bit confusing. Be sure to research everything you need to know about renting a car in Hawaii.

Top 10 Best Kauai Adventures for Families

The Hawaiian islands are a top family vacation spot year after year. There are so many family activities on Oahu, Maui, and the Big Island of Hawaii. Kauai is no different.

Kauai is arguably the best Hawaiian island for families because of its slower pace, beautiful beaches, and generous activities geared toward young kids.

As promised, here is our top 10 list of the best adventurous things to do on Kauai with kids.

1. Hike to Hanakapi’ai Falls

One of the more adventurous hikes on Kauai, Hanakapi’ai Falls is about an 8-mile out-and-back trail. The first two miles are along the Na Pali Coast spoil you with beautiful ocean views all the way to Hanakapiai Beach. This initial stretch is doable for little kids and toddlers in backpacks.

The final two miles up to the falls will have you traversing 5 different river crossings. This is a much more difficult section. In some parts, you will need to climb over boulders and through muddy sections of the trail.

Make sure to take plenty of water as there are no facilities on this trail and wear appropriate shoes! If you’re feeling extra brave, then don’t stop at Hanakapi’ai Falls. Instead, continue on the trail and it will lead you to Hanakoa Valley.

If you are not a resident of Hawaii you will need to make a reservation at the Ha’ena State Park website.

2. Rafting Expedition Down the Napali Coast

Calling all thrill seekers! A rafting tour of the Napali Coast is not for the faint of heart. This 12-mile journey will take you on waves up to 20 feet high, through sea caves, and past towering cliffs of the Na Pali Coast State Park.

There’s nothing better to get your heart pumping than a good zipline. Kauai’s south shore is home to Koloa, one of the best ziplines in Hawaii.

4. Explore Queen’s Bath

Once a secret spot known only to locals, Queen’s Bath is a natural tidepool on Kauai’s North Shore. A steep and rocky but short 15-20 minute hike down the cliff will get you to the edge of the clear blue pool that is often full of marine life.

Taking a dip in Queen’s Bath is a total trip but make sure to only get in when the conditions are safe (especially with young children). There are some other little tidepools with shallow water in the same area. This is an ideal place for the younger kids to play.

Make sure not to go too close to the edge and keep an eye on the little ones when conditions are not right. Strong waves have been known to sweep people off their feet and into the sea!

5. Hike Waimea Canyon

Known as the Grand Canyon of the Pacific, Waimea Canyon State Park is a must-see, popular spot for any family vacation. The 10-mile-long, 3,000 feet deep canyon was formed by a collapse of a volcano in the area.

Another exciting Kauai adventure for families is floating down the historic plantation ditches.

The whole family will enjoy this unique experience but it’s recommended that children over 6 and adults ride in their own tubes. Life jackets and helmets are provided so you can stay safe while you enjoy the ride down!

7. Whale Watching Tour

If you’re trip lands during whale season, then you should definitely book a whale-watching tour.

Kauai’s waters are home to Humpback whales from December until April. These reasonably priced tours will get you close to the whales so you can get an up-close look at these gentle giants.

The adventure part comes in when you are trying to locate Hideaways Beach, which is not an easy task. It requires some scrambling down steep steps that involve sketchy handrails and tattered ropes.
