The East Side: Rivers, Waterfalls, and Royal History

The East Side, affectionately known as the Coconut Coast for the vast groves of coconut palms that line its shores, is the bustling heart of Kauai. It's home to the island's main towns, Kapaʻa and Līhuʻe, and was the seat of power for Kauai's ancient aliʻi (royalty), who centered their lives along the sacred Wailua River. Its central location makes it an incredibly convenient base for exploring the entire island.

12. Conquer Nounou Mountain (Sleeping Giant) Trail

Looming over Kapaʻa is the Nounou Mountain range, which from a distance looks exactly like a giant lying on his back. There are three trails to the summit, but the most popular and direct is the Nounou East Trail. It's a moderately challenging hike that climbs about 1,000 feet via a series of switchbacks through a forest of ironwood and guava trees. Your reward at the top (on the giant's chest) is a picnic shelter and a breathtaking 360-degree view of the eastern coastline and the island's interior mountains. The trail can get very muddy after rain, so wear appropriate footwear.

13. Take the Peaceful Kuilau Ridge Trail

For a more relaxed hiking experience with equally beautiful scenery, the Kuilau Ridge Trail is a fantastic choice. This wide, gently graded trail offers stunning views of the lush Keahua Arboretum and the Makaleha Mountains. It's an excellent option for families or for a peaceful walk through the jungle without a strenuous climb.

14. Swim at Lydgate Beach Park

Without a doubt, this is the best family beach on Kauai. The key feature is two large, man-made ponds enclosed by lava rock walls. These walls break the surf, creating incredibly calm, protected swimming areas that are perfect for keiki (children) and anyone new to snorkeling. The park also features lifeguards, picnic facilities, and Kamalani Playground, one of the best playgrounds on the island.

15. Surf at Kealia Beach

Just north of Kapaʻa, Kealia is a long, wide, and beautiful golden-sand beach that's easily accessible from the highway. It's a popular spot for surfers and boogie boarders, with a lifeguard tower ensuring safety. The Ke Ala Hele Makalae, Kauai's coastal bike path, runs right alongside it, making it a perfect place to stop for a swim during a ride.

16. Kayak the Sacred Wailua River

As Hawaii's only navigable river, the Wailua is not just a natural wonder but also one of the most sacred areas in Hawaiian history. There are two classic ways to experience it. For the adventurous, you can rent a kayak and paddle upstream, taking a turn into a tributary that leads to a short jungle hike and the beautiful Uluwehi Falls, often called Secret Falls. For a more relaxed journey, take one of the famous open-air boat tours. These guided cruises share the legends of the area and culminate at the Fern Grotto, a lush, lava-rock cave draped in hanging ferns where you'll be serenaded with Hawaiian music.

17. Admire ʻŌpaekaʻa Falls

Meaning "rolling shrimp" in Hawaiian, this stunning 151-foot waterfall is one of the most accessible on the island. A convenient roadside lookout on Kuamoʻo Road provides a perfect vantage point for photos.

After you've admired the falls, walk across the street from the lookout. There's another viewpoint there that offers a spectacular panoramic view of the Wailua River valley below, a perspective many visitors miss.

18. Marvel at Wailua Falls

This powerful, 84-foot double-tiered waterfall gained international fame in the opening credits of the 1970s TV show Fantasy Island. Located just a few miles inland from Līhuʻe, it's another waterfall that you can drive right up to, making it a quick and rewarding stop.

19. Explore Kapaʻa Town

"Old Kapaʻa Town" is a vibrant, historic hub with an eclectic mix of boutiques, art galleries, and some of the best food on the island. It has a genuine feel that makes it a joy to explore on foot. The Ke Ala Hele Makalae coastal path runs right through the heart of town, perfect for renting a bike, cruising along the ocean, and stopping for lunch at one of the many fantastic food trucks or cafes.

20. Learn at Līhuʻe's Museums

Līhuʻe, the county seat, is home to two of the island's most important cultural institutions, both of which are perfect rainy-day activities. The Kauai Museum preserves the art and history of Kauai and Niʻihau, from their geological origins to the monarchy era and beyond. A few blocks away, the Grove Farm Museum offers a fascinating, preserved glimpse into life on a 19th-century Hawaiian sugar plantation, the industry that shaped modern Hawaii.

21. Respect Poliʻahu Heiau

Located on the same road as ʻŌpaekaʻa Falls, this is one of Kauai's most significant ancient sites. This large heiau (sacred temple) was a place of worship for ancient Hawaiians. As with all sacred sites on the island, it's a place to be viewed with reverence and respect from a distance, not a site to be walked upon.
