Hiking Adventures

Explore the Na Pali Coast Trail

The Na Pali Coast Trail, also known as the Kalalau Trail, is arguably the most famous hiking destination in Kauai and one of the top activities to do in Kauai for outdoor enthusiasts. This 11-mile trail along Kauai's northwest shore offers some of the most spectacular coastal views in the world, with dramatic cliffs, pristine beaches, and lush valleys.

The trail begins at Ke'e Beach and winds through five major valleys before reaching Kalalau Beach. While the full trail requires a permit and is best suited for experienced hikers, even a short hike to Hanakapi'ai Beach (2 miles each way) provides breathtaking views and is accessible to most fitness levels. The trail is challenging with steep inclines and can be muddy, so proper hiking shoes are essential.

Discover Waimea Canyon

Often called the "Grand Canyon of the Pacific," Waimea Canyon offers numerous hiking opportunities and is definitely one of the must-do activities to do in Kauai. The canyon stretches 10 miles long and over 3,600 feet deep, featuring vibrant red and green landscapes that change with the light throughout the day.

Popular hikes include the Canyon Trail to Waipo'o Falls, which offers stunning views of the canyon and waterfalls, and the Awa'awapuhi Trail, which provides panoramic views of the Na Pali Coast. The Waimea Canyon Lookout and Pu'u Hinahina Lookout offer easier access to incredible views without strenuous hiking.

Hike the Sleeping Giant (Nounou Mountain)

The Sleeping Giant Trail, named for the mountain's resemblance to a giant lying on its back, is one of the most popular and accessible hikes on Kauai's east side. This moderate 3.2-mile round-trip hike offers panoramic views of the Wailua River, Mount Waialeale, and the surrounding coastline.

The trail has three different approaches, with the east trail being the most popular. The hike takes about 2-3 hours round trip and includes some steep sections, but the summit views make it well worth the effort. This is an excellent option for those seeking activities to do in Kauai that combine exercise with stunning scenery.

Water Activities

Snorkeling at Tunnels Beach

Tunnels Beach (Makua Beach) on Kauai's north shore is renowned for its excellent snorkeling conditions and is considered one of the best activities to do in Kauai for marine life enthusiasts. The beach gets its name from the underwater lava tubes that create unique snorkeling experiences.

The calm, clear waters are home to vibrant coral reefs, tropical fish, sea turtles, and occasionally monk seals. The best snorkeling is typically in the morning when the water is calmest. Remember to use reef-safe sunscreen to protect the delicate marine ecosystem.

Kayaking the Wailua River

Kayaking the Wailua River is a quintessential Kauai experience and one of the most popular activities to do in Kauai for water sports enthusiasts. The Wailua River is Hawaii's only navigable river and offers a serene paddling experience through lush tropical landscapes.

Popular kayak tours combine paddling with hiking to Uluwehi Falls (Secret Falls), a beautiful 120-foot waterfall. The journey takes you through the Wailua River Valley, past ancient Hawaiian sites, and into the heart of Kauai's rainforest.
