Golden beaches. Lapping waves. Pristine rainforests. If that sounds like your vision of paradise then it may be time to add Kauai to your family vacation ideas list. It’s the fourth largest of the Hawaiian islands at roughly 552 square miles, yet only three percent of it is developed for commercial and residential use. The rest is pure tropical bliss.

Where to Go on Kauai

Nicknamed the “Garden Isle,” Kauai is geographically divided into five major resort areas: North Shore, South Shore, West Coast, East Coast, and Lihue. Lihue, the island’s capital city, is the location of the airport and home to the popular tourist draws Kalapaki Beach and Wailua Falls. For many visitors, this is the starting point of any Kauai vacation.

A scenic 45-minute drive from the airport, the North Shore is where you’ll find Haena State Park, which includes the Kalalau Trail, Hanakapiai Falls, and Kee Beach. The South Shore is popular for Poipu Beach Park and Baby Beach, where families enjoy snorkeling and water sports. The West Coast features Waimea and its legendary canyon, historic Hanapepe Town, and Na Pali Coast tours. The East is home to shops, hotels, and the Ke Ala Hele Makalae (“The Path That Goes by Coast”), an idyllic multi-use trail known for its historic sites and coastal views.
