How Many Hawaiian Islands Do You Know?

The most well known Hawaiian islands are the eight largest of the island chain. But even with these eight islands being the largest, many people only know of four of the islands off the top of their head: Big Island, Maui, Kauai, and Oahu. It makes sense that these four islands come to mind first because they are the four largest islands of Hawaii.. Skyline Eco-Adventures has zipline adventure tours on two of these four popular islands. We have a tour near Poipu on Kauai, and two tours on Maui. One of our Maui tour locations is in Ka’anapali and the other is on Mt. Haleakalā, near the entrance of Haleakalā National Park.

So, how many Hawaiian islands are there? The 8 largest are the most well known but there are 137 islands and 5 counties that, together, form the state of Hawaii. The 5 counties are Hawai’i, Honolulu, Kauai, Maui, and Kalawao. Kalawao is a unique county because it is under the jurisdiction of Hawaii’s state health department. Hawaii’s other four counties each have their own local governments, just like the other counties within states in the United States.

Big Island

Big Island is the largest and youngest island in the Hawaiian island chain spanning 4,028 square miles. It boasts a diverse landscape that ranges from lush rainforests to volcanic deserts and black sand beaches. There are five volcanos that make up Big Island’s land mass. MaunaKea is one of those volcanoes. Few people know that there is a lake just below the summit of MaunaKea called Lake Waiau. Big Island has the most volcano activity out of all of the Hawaiian islands. In fact, Kilauea is the single most active volcano on Earth.

Beyond its natural wonders, the Big Island is a gateway to rich cultural traditions and warm aloha spirit. Stroll through charming towns like Hilo and Kona, where local farmers’ markets and historic landmarks blend with vibrant modern communities. Savor the flavors of the island with fresh poke, Kona coffee, and farm-to-table cuisine. From stargazing at world-class observatories to relaxing on pristine beaches, the Big Island offers an unparalleled mix of adventure, relaxation, and discovery.

Maui

Maui is the second largest of the islands of Hawaii at 727 square miles. Skyline Eco-Adventures has two tour locations on Maui. In fact, we established the first commercial zipline tour in the United States on Maui in 2001 just outside of Haleakalā National Park. This zipline course is still one of our most popular and award-winning courses today! We also have an incredible zipline course located near the resort area in Ka’anapali. Maui’s most famous historic areas are Haleakalā National Park and the Road to Hana.  Maui’s climate is very diverse in different parts of the island. Some areas are warm, tropical and lush while others, like Upcountry Maui, are drier and can be chilly at times due to the difference in elevation.

This island offers a little bit of everything. Visit Lahaina, a historic whaling town filled with art galleries, shops, and restaurants, or experience a traditional Hawaiian luau complete with music and hula dancing. For foodies, Maui’s traditional dishes and fresh seafood provide a true taste of Hawaii’s islands.

Kauai

Kauai is the third largest island in the Hawaiian island chain reaching 562 square miles. This island is the wettest of the islands in Hawaii. Because of its lush greenery and high rainfall averages throughout the year. Skyline Eco-Adventures also has a zipline course on Kauai in Poipu. Kauai has more beaches, rivers, streams, and waterfalls than any other Hawaiian island. This is due in part to its rainy climate. This island is also known as the Garden Isle.

What sets Kauai apart is its peaceful atmosphere and deep sense of connection to the land. Wander through quaint towns like Hanalei or Kapa’a, where local artisans and farmers dining bring the island’s spirit to life. Whether you’re enjoying the beach or savoring the splendor of a Kauai sunrise, this island offers moments that feel timeless.

Oahu

Oahu is known for its diverse culinary, entertainment and art traditions. Measuring 597 square miles, this island is home to the state capital of Hawaii, the city of Honolulu. A dynamic blend of cultural landmarks, iconic beaches, and thrilling adventures, Oahu mixes urban energy with breathtaking scenery. From the bustling streets of Honolulu to the world-famous surf of the North Shore, there’s something for everyone. Explore the historic significance of Pearl Harbor, hike the famous Diamond Head Crater for panoramic views, or soak up the sun on Waikīkī Beach, where the energy is as lively as the waves.

Beyond its postcard-perfect scenery, Oʻahu is a melting pot of cultures and traditions. Savor local flavors at food trucks in Haleʻiwa, shop in chic boutiques in Kailua, or attend a traditional Hawaiian luau to immerse yourself in the island’s rich heritage. For outdoor enthusiasts, snorkeling at Hanauma Bay, paddling an outrigger canoe, or taking in the beauty of the lush Koʻolau Mountains is a must. Whether you crave adventure, culture, or relaxation, Oʻahu offers a unique blend of experiences that make every moment unforgettable.

Molokai

Molokai, reaching 260 square miles long, is the fifth largest of Hawaii’s islands. On this island, you will find a 500-acre coffee plantation and miles of untouched landscapes. It is called the enlightening isle because its remoteness helps you find yourself and reset your perspectives about life.

Moloka’i offers an unspoiled and authentic experience far from the hustle of tourist hotspots. With no traffic lights and a community deeply rooted in Hawaiian traditions, it’s a haven for those seeking simplicity and a deep connection to the land and its people. Explore towering sea cliffs along the Kalaupapa Peninsula, hike through serene valleys like Halawa, or relax on Papohaku Beach, one of Hawaii’s largest white sand beaches, often so quiet it feels like your private retreat.

Lanai

Lānaʻi is a secluded 140 square mile escape that feels worlds away from the rest of the islands of Hawaii. Known for its quiet luxury and untouched landscapes, Lānaʻi offers an intimate Hawaiian experience unlike any other. This small island is home to pristine beaches, rugged trails, and a sense of tranquility that invites you to slow down and savor every moment. Spend your days exploring the striking rock formations at Keahiakawelo, also known as the Garden of the Gods, or relaxing on Hulopoʻe Bay, a crescent-shaped beach perfect for snorkeling and spotting dolphins.

Niihau

Niʻihau, often referred to as the “Forbidden Island,” is a place of mystery and preservation, offering a glimpse into a way of life that has remained largely untouched by modern influences. Privately owned and home to a small, predominantly Native Hawaiian community, Niʻihau is dedicated to preserving Hawaiian traditions, language, and culture. Access to the island is highly restricted, which has allowed its natural beauty and cultural heritage to remain intact. Visitors can experience its pristine environment through limited, guided tours, often focused on snorkeling or exploring its unspoiled coastline.

Kahoolawe

Out of the eight main islands, Kahoolawe is the smallest Hawaiian island only reaching about 45 square miles.  There is no permanent population of this island. The only way to visit this island is by participating in volunteer work opportunities, otherwise, it is completely off-limits to the general public.

Deeply tied to Hawaiian tradition, Kahoʻolawe is seen as a sacred place, a piko (center) for navigation and spiritual connection. Today, the island serves as a living classroom for cultural education and environmental stewardship. Volunteers and organizations work tirelessly to plant native vegetation, prevent erosion, and honor its legacy as a cultural treasure. Though not a typical tourist destination, Kahoʻolawe holds a unique place in Hawaii’s story, symbolizing the strength of Hawaiian culture and the enduring bond between land and people.
