Wild, lush, and wonderfully untamed, Kauai feels like stepping into another world. Known as the Garden Isle, it’s a place where emerald cliffs plunge into the Pacific, waterfalls spill from jungle ridgelines, and quiet beaches invite you to slow down and stay awhile. Whether you’re hiking dramatic coastal trails, floating through old sugarcane tunnels, or chasing waterfalls after a tropical rain, Kauai offers experiences that feel both adventurous and deeply grounding. This list highlights ten of our favourite things to see and do—perfect for first-timers or return visitors looking to experience the island beyond the resort.
1. Mountain Tubing
The historic Lihue Plantation ditch and tunnel system, which once irrigated vast sugar crops, had been unused after sugar production stopped. Refurbished into a tubing system with tunnels, small drops and generally gorgeous views, this is a unique, laid-back activity! We booked the Mountain Tubing Adventure with Kauai Backcountry Adventures a few days in advance.
The day started with a drive through a former Lihue sugar cane plantation, where our guide shared history, information, and tips on the island. Once we arrived at our starting point, we hopped in a tube, donned a headlamp, and began the float down the old irrigation canals, through several tunnels and flumes, engineered and hand-dug circa 1870. It was a relaxing way to spend the morning and learn a little bit of Kauai’s history.
2. Nā Pali Coast
By trail
Kalalau Trail or part of the Kalalau Trail to Hanakāpīʻai Falls
The first 2 miles boast stunning views of the blue water, sandy beaches and lush mountain sides. Each new view was awe-inspiring, and I could not get enough. Hanakapiai Falls is a 300 ft waterfall with a large pool below, perfect for taking a dip. Read this post for more details on the hike.
By Boat
Seeing the Nā Pali Coast from the water is just as jaw-dropping as hiking it—if not more. Towering emerald cliffs, sea caves, waterfalls, and hidden beaches unfold as you cruise along the coast. Boat tours depart from Port Allen (south shore) and Hanalei (north shore) and range from large catamarans to fast zodiac rafts. Many tours include snorkelling stops, dolphin sightings, and seasonal whale watching (winter). Morning tours tend to be calmer, especially in summer.
3. Hanalei Town & Beach
Hanalei is the heart of Kauai’s laid-back north shore. This small town blends surf culture, art galleries, local boutiques, and casual eateries with one of the most beautiful backdrops on the island—tarо fields, mountains, and Hanalei Bay. It’s an easy place to spend a slow afternoon shopping, grabbing fish tacos, or watching surfers at sunset. If you are driving in, make sure to stop at the viewpoints for some breathtaking vistas – Hanalei Valley Lookout and Hanalei Bay Lookout, then enjoy the iconic Hanalei one-lane steel bridge. A great option for breakfast or lunch is the Hanalei Bread Company – though everyone else thinks that too, so it’s often busy!
4. Waimea Canyon
Often referred to as the Grand Canyon of the North, Waimea Canyon is a spectacular mix of red ochre rock and the lush greens of grasses and plants. Then you add the blue sky, and you have such vibrant and contrasting colours. Driving up to the National Park itself was a delight for the eyes. Red ochre dirt surrounded the path. We stopped near a little waterfall that just seemed so out of place; the red dirt made the area seem desert-like. We had not planned for any hikes or walks, but there are many trailheads in the National Park. Saving those for next time.
Bonus idea: if you are driving, on your way back from the Canyon, stop in Hanapepe, cross the Swinging Bridge, visit the Kauai Brewing Company and/or the Kauai Coffee Company. You can also drive through the Tree Tunnel – a section of road lined on both sides by high, arching trees.
5. Luau
As with any Hawaiian holiday, a luau is a must. The one we attended – Luau Kalamaku – was awesome. The pig was succulent, smoky and salty. My mouth waters thinking of it. The show was exciting – the fire throwers were spectacular, having everyone on the edge of their seat. Plus all the Mai Tais and Blue Hawaiians you want…
6. Limahuli Garden & Preserve
Tucked at the end of the road past Hanalei, Limahuli Garden & Preserve offers a deeper look into Kauai’s natural and cultural history. The garden showcases native Hawaiian plants, ancient taro terraces, and stunning views of the NāPali cliffs. It’s peaceful, educational, and far less crowded than many other attractions—ideal for travellers who enjoy nature with context and meaning.
7. Beaches
Kauai’s beaches vary widely depending on season and location. These are some of the popular ones:
- Hanalei Bay: Wide, scenic beach ideal for lounging, walking, and sunset views. Always check conditions—winter swells on the north shore can be powerful.
- Poipu Beach (South Shore): Great for swimming and beginner snorkelling year-round. Take the car for a short drive to Spouting Horn Park to experience the drama of the ocean exploding up through a small hole in the rock.
- Tunnels Beach (North Shore): Incredible snorkelling in calm summer conditions
- Lydgate Beach: Protected lagoons, perfect for families and calm swims
A fun tip we picked up from the locals – fish like frozen peas – bring them with you while you snorkel, and you will have fish swarming you!
8. Sleeping Giant Hike
The Sleeping Giant hike on Nounou Mountain offers one of the best views for relatively moderate effort. Located near Kapaa, this trail climbs through forested switchbacks to panoramic views of the east coast. It’s a great half-day hike option.
9. Chasing Waterfalls
Kauai’s nickname, The Garden Isle, comes to life when waterfall chasing. Highlights include:
- Wailua Falls: Easily accessible and dramatic
- ʻŌpaekaʻa Falls: Roadside viewpoint with lush surroundings
- Kilauea Falls (seasonal): Visible after heavy rain near Kilauea. Not always flowing, but beautiful when active.
- Ho‘opi‘i Falls: Located near Kapaa, this easy-to-moderate hike leads to two waterfalls. The lower falls are swimmable and less crowded than Secret Falls.
- Kipu Falls (view only): Once famous for cliff jumping, it’s now closed for swimming, but still worth mentioning as a scenic stop near Koloa.
These waterfalls are accessible via big hikes or helicopter-only:
- Waipoo Falls (Waimea Canyon): Accessed via a canyon-edge hike with sweeping views. You can hike to the top or down into the canyon for a different perspective.
- Manawaiopuna Falls (Jurassic Falls): Made famous by Jurassic Park. Located on private land and only accessible by a helicopter tour.
- Countless Nā Pali Coast Waterfalls: After rain, dozens of temporary waterfalls cascade down the cliffs—best seen by boat or helicopter.
10. Kayak the Wailua River
Paddling the Wailua River is a uniquely Kauai experience. You can kayak upriver through lush jungle scenery and combine it with a short hike to Secret Falls (Uluwehi Falls). It’s an accessible adventure that blends water, rainforest, and light hiking—all without ocean conditions to worry about.
Final Thoughts
Kauai isn’t about rushing from one attraction to the next—it’s about letting the island set the pace. Some of our favourite moments came between the highlights: a quiet beach at sunset, mist rising in Waimea Canyon, or the sound of waterfalls after a passing shower. Whether you’re here for adventure, relaxation, or a bit of both, Kauai has a way of staying with you long after you leave.
