1. Swim in Hanalei Bay

Its crescent-shaped shoreline, backed by emerald mountains and waterfalls, makes it perfect for swimming, paddleboarding, and relaxing on the sand. During the summer, the water is calm and clear, creating ideal conditions for families and casual swimmers.
In the winter, the bay becomes a popular surf spot, attracting both locals and visitors. Staying nearby in our Hanalei Bay, Kauai vacation rentals means you’ll wake up just steps from this iconic destination, making sunrise swims and sunset strolls part of your daily routine.
2. Visit Nāpali Coast State Wilderness Park
Nāpali Coast State Wilderness Park lies in the northwest side of the Kauai island. It’s known for its towering pali, or sea cliffs. You can also admire narrow valleys, streams, and beautiful cascading waterfalls. The Kalalau Trail is a steep footpath running through the park, between nearby Ke’e Beach and sandy Kalalau Beach. It cuts through 5 valleys, including the Hanakoa Valley. On this trail, you can see lots of native plants and old agricultural terraces
3. Hike the Kalalau Trail
The Kalalau Trail is one of Hawaii’s most famous hikes, stretching 11 miles along the rugged Napali Coast. Even if you don’t complete the full trek, the first two miles to Hanakapi’ai Beach offer a challenging yet rewarding experience.
Permits are required for those hiking beyond Hanakapi’ai Beach, but the effort is worth it for the chance to experience some of Kauai’s most dramatic scenery. For hikers, this trail is an essential adventure.
4. Go Snorkeling at Tunnels Beach
Tunnels Beach, also known as Makua Beach, is one of the best snorkeling destinations on the island. Its protective outer reef makes the waters calm and full of marine life, from colorful fish to sea turtles. The underwater terrain includes lava tubes and arches, creating a unique environment to explore.
The beach is also a great spot for sunbathing, swimming, or simply taking in the surrounding views of Bali Hai, the mountain backdrop made famous in Hollywood films. Just remember to bring reef-safe sunscreen to protect both your skin and the marine ecosystem.
5. See the Kilauea Lighthouse
Perched on a dramatic bluff on Kauai’s north shore, the Kilauea Lighthouse is a historic landmark with breathtaking views of the Pacific Ocean. Built in 1913, the lighthouse once guided ships traveling across the Hawaiian Islands. Today, it serves as a popular visitor attraction and a prime location for birdwatching.
Depending on the season, you may even spot humpback whales breaching offshore or dolphins playing in the waves. The surrounding area is part of the Kilauea Point National Wildlife Refuge, home to native seabirds like the red-footed booby.
6. Explore the Napali Coast
The Napali Coast is one of the most photographed regions of Kauai, known for its towering sea cliffs, lush valleys, and cascading waterfalls. The coastline is accessible by hiking, boat, or helicopter, each providing a different perspective on its natural beauty.
Boat tours allow you to explore hidden sea caves and secluded beaches, while helicopter tours showcase the scale of the cliffs and valleys. Whether you see it from the water or the sky, the Napali Coast is an unforgettable part of your Kauai journey.
7. Soak in the Sights at Hanalei Valley Overlook
This beautiful overlook on Kauai’s North Shore has panoramic views of the surrounding lush valley. This valley has historic taro fields, mountains, and a winding river. If you end up traveling between Princeville and Hanalei Bay, this spot should be on your way. It’s totally worth the stop to take some pictures and soak in the scenic view for a few minutes (or longer).
8. Visit Hanalei National Wildlife Refuge
The Hanalei National Wildlife Refuge protects thousands of acres of wetlands and is a sanctuary for native Hawaiian birds. Located in the Hanalei Valley, the refuge is especially known for its taro fields and sweeping mountain views.
Birdwatchers will enjoy spotting species like the Hawaiian coot and Hawaiian duck, both of which are endangered. Even if you’re not a birder, the refuge provides a peaceful place to connect with Kauai’s natural landscapes and cultural history.
9. See the Princeville Botanical Gardens
The Princeville Botanical Gardens are located near the Hanalei National Wildlife Refuge. It has an area of 9 acres, giving you lots of room to walk around and explore. The area farms chocolate, honey, and a variety of fruits. You can enjoy tastings of these locally sourced goods, as well as guided tours of the gardens.
10. View the Maniniholo Dry Cave
Located across from Haena Beach Park, the Maniniholo Dry Cave is a fascinating stop for visitors exploring Kauai’s north shore. The cave stretches back about 300 feet, making it one of the largest dry caves on the island.
