Kauai Island, the oldest and northernmost island in the Hawaiian Island chain, is often referred to as the "Garden Island" and full of adventure. We have put together a list of our favorite family-friendly activities to do on Kauai. Check out the activities and find the perfect Oceanfront Rentals on Kauai house for your families next Hawaiian adventure!
1. Snorkel the Waters
Kauai’s Clear waters and amazing coral reefs are perfect for snorkelers of any age. While some of the beaches have snorkeling areas, the Na Pali Coast is definitely the best place to go. The Na Pali Coast is not accessible by car so the best way to get there is through boat snorkeling tours. These tours are a great option because they also provide all the gear you will need.
2. Go Mountain Tubing
If you are looking for a unique experience that the whole family can enjoy mountain tubing is perfect. You will float down the gently flowing waters while also getting a look at Kauai's historical engineering feats by traveling through canals, tunnels and flumes hand dug in the 1890's. Book your trip with Kauai Backcountry Adventures and they will take care of everything including gear and the backcountry drive through the former Lihue Plantation.
3. Zipline
What could be better than flying high over tree canopies, water, grazing animals and a plantation? Not much! The Koloa Zipline Company course consists of 8 lines and lasts 3.5 hours. The course includes one of the longest lines on the island and goes for a half a mile. Their special harnesses lets you fly head first, hand free, or in the traditional seated position.
4. See Marine Creatures in the Wild
Kauai has so many options when it comes to seeing the marine creatures in their natural habitat. You can see dolphins from dolphin charters or snorkeling and sunset cruises. Companies like Blue Dolphin Charters will guarantee your money back if you don’t see any. You can also take whale watching trips, but be sure to go during peak viewing season, November- April.
Want to stay on dry land? The Hawaiian Monk Seals can sometimes be seen sunbathing along Kauai’s shoreline. The Kilauea Lighthouse and Wildlife Refuge is another great place to see different types of Kauai wildlife.
The best way to see the Island of Kauai if from the air. Most of the island is inaccessible by foot which in part contributes to its lasting beauty. With a helicopter tour, you will be able to see many of the places that most people don’t. Although these tours can be pricey they are, in our opinion, worth every penny.
If you’re looking to experience breathtaking views in Kauai’s backcountry, horseback riding is a fun and relaxing alternative that allows you to cover a lot of ground while being immersed in nature. From exploring waterfalls to enjoying Mahaʻulepu Beach with its diverse landscape and clear waters, you can choose options from quick tours to half-day adventures.
7. See Fern Grotto
While you’re making your voyage on the Wailua River, don’t miss Fern Grotto. Formed millions of years ago, Fern Grotto is a lava-rock cave that is now covered by tropical plants and hanging ferns. Today, Fern Grotto acts as a natural amphitheater in a peaceful setting.
8. Kayak In Wailua River 
At 20 miles long, the Wailua River is Kauai’s largest and longest river and one of Hawaii’s only navigable rivers. The slow-moving ribbon of water winds through lush landscapes and past classic Hawaiian waterfalls including Opaekaa Falls and Wailua Falls. With its mellow flow, kayaking the Wailua River should be on your must-do in Kauai list! Consider taking a guided kayak tour for a full experience or rent your own kayak or stand up paddleboard.
9. Ride the Train 
All aboard the Kauai Plantation Railway for a day of family fun! The railway offers a guided train-hike-orchard tour through the sites of old sugar cane plantations and the Kilohana plantation, which still grows more than 50 fruits and vegetables and is home to an array of farmyard animals. Enjoy a picnic and entertain your kids by feeding the resident goats, sheep, pigs, and more.
Whether you’re in the mood for swimming, surfing, or strolling along our shorelines, the North Shore is a sight to behold with its white sand, turquoise water, and mountain views. In the winter, the North Shore beaches are known for their surf breaks. For swimming and snorkeling, check out the reef-protected waters of Makua (Tunnels), Ke’e, and Haena beaches. Hanalei Bay Beach Park and Kahili Beach/Kilauea Bay are great North Shore options as well!
