Top Kauai Sights & Attractions
Wailua River Cruise to Fern Grotto
Only accessible by boat along the Wailua River, Kauai's Fern Grotto is a natural formation of lava rock that has accumulated a spectacular assemblage of fern, moss and other vibrant flora. This natural curiosity has attracted visitors for years, and river boat service offers an affordable method of transportation with the added benefit of local Hawaiian music. A great stop to add to any Kauai trip.
Na Pali Coast Adventure Tours
A visit to the Na Pali Coast along the northern shore of Kauai is like a trip through time, back to an ancient era when things were incomparably larger and somehow brighter. From mist-shrouded peaks down rippling, carved cliff faces to the waves that splash through arches and sea caves along the base, the Na Pali Coast is a sight to behold. While it is possible to hike a majority of the Na Pali Coast, boat and helicopter are the most popular ways to experience this incredible natural wonder.
Waimea Canyon Tours
On the west side of the island of Kauai stands beautiful Waimea Canyon, a vast 3,500-foot deep canyon famous for its spectacular panoramic views of steep cliffs, rugged valleys, and breathtaking peaks. Views from the summit can stretch for miles, earning this island gem the title "The Grand Canyon of the Pacific". A variety of sightseeing tours will lead you to this beautiful landmark and its favorite scenic spots for the most picturesque vistas.
Jurassic Falls Kauai

Hanalei Bay
Experience the beauty of Hanalei Town and explore this island's gem graced with a rich history and peaceful green landscapes. From taro fields to the Hanalei Mountains, Lagoon and Pier, there are a few amazing tours and activities in Hanalei to choose from that will be sure to delight people all ages. See where the classic movie musical "South Pacific" was filmed or get easy access to the coast and cliffs of Na Pali or simply relax and experience the northern sunset that Hanalei is known for.
Wailua Falls
Wailua Falls forms two distinct cascades near the head of the Wailua River. These streams drop 200 feet, churning up heavy clouds of mist that often form rainbow colors over the river's surface below. Many visitors already familiar with Wailua Falls due to their appearance in the popular television series, "Fantasy Island".
Wailua River
The serene Wailua River flows down the east side of Kauai, past lush jungles and cascading waterfalls rushing from the wettest spot on earth, Mt. Waialeale. A paradise for kayakers, with relatively calm water and plenty to see along the way, the Wailua River attracts leisure travelers and adventurers alike.
Opaekaa Falls
Opaekaa Falls is a beautiful, 150-foot waterfall found in Wailua. Known for being one of Kauai's most easily accessible waterfalls, you can view the majestic falls from a vista conveniently located on the side of Kuamoo Road. The name "opae-kaa" (shrimp-rolling) comes from the days when there were many freshwater shrimp in the stream, a lot of which would roll down the waterfall into the pool below. Opaekaa Falls flows year round, so it's worth visiting for anyone on the East Side.
Poipu Beach
Poipu Beach is hailed as one of the best beaches in the United States, and with good reason. It's perpetually sunny weather and calm shallow water attract snorkeling fans, swimmers and vacationers of all ages. When most people close their eyes and imagine a beach in Kauai, they are thinking of Poipu Beach.
Spouting Horn
This spectacular natural geyser forms when waves push under a shelf of volcanic rock, causing a pillar of water to rush upward. Blowholes like Spouting Horn, found elsewhere throughout Hawaii, are created when remnants of an ancient lava tube succumbs to tidal forces and erosion, finally producing an opening through which rushing sea water can emerge from. Visitors often enjoy the challenge of timing the perfect photo to catch a rainbow that flashes as the Spouting Horn erupts.
Hanapepe
"Kauai's biggest little town!" Hanapepe is an old settlement on the southwest coast of Kauai. Seemingly surrounded by plantation lands, Hanapepe is home to Port Allen Harbor and Port Allen Airport, as well as the famous Glass Beach, which was created by years of discarded glass being smoothed by the ocean and turned into a sand-like texture. The town's quaint charm and authentic historical aesthetic inspired the setting of the Disney film "Lilo & Stitch."
Kalalau Lookout
Kalalau Valley, one of the most beautiful valleys of the Na Pali Coast, is accessible only via an 11-mile hiking trail that begins in Haena State Park on the North Shore and continues along the Na Pali Coast. The Kalalau Trail is the only way to access Kalalau Beach, as boat landings aren't permitted. The Valley can also be viewed from Kalalau Lookout, located in Kokee State Park, or from a helicopter tour, most of which fly past the Na Pali Coast.
Lehua Crater
Lehua Crater is a sunken atoll off the North coast of Niihau, directly West of Kauai. A restricted Hawaii State Wildlife Sanctuary, Lehua's crescent shape makes it an excellent spot for snorkeling and scuba diving. This hidden gem is a definite "must-see" for anyone visiting the Garden Isle! Fans of Maui's famous Molokini Islet should definitely set their sights on Kauai's next big snorkeling destination.
Kilauea Lighthouse
Visit the historic Kilauea Point Lighthouse & Wildlife Refuge, where you can enjoy breathtaking ocean views and observe native Hawaiian seabirds in their natural habitat.
