Hiking Heaven: Trails for Every Level
Kauai’s hiking scene is incredibly diverse, offering everything from easy coastal walks to challenging treks into the island’s interior. No matter your fitness level, there’s a trail waiting to be conquered.
Kalalau Trail (Hanakapiai Falls Section)
Let’s start with the iconic Kalalau Trail. This 11-mile (one way) behemoth along the Na Pali Coast is famous for a reason – the views are absolutely stunning. However, we’re focusing on the first two miles to Hanakapiai Beach and then another two miles inland to Hanakapiai Falls. This section, while still challenging, is manageable for most reasonably fit hikers.
The Grind: The initial two miles to Hanakapiai Beach are a constant up-and-down battle, with uneven terrain and stream crossings. Be prepared to get your feet wet. The additional two miles to Hanakapiai Falls involve navigating rocky paths and more stream crossings.
Permits and Parking: Accessing the Kalalau Trail requires a reservation and permit, even for day hikes. You can book yours through the Hawaii Department of Land and Natural Resources (DLNR). Parking at Ke’e Beach is extremely limited and requires advanced reservations as well. Consider using the shuttle service from Waipa Park & Ride to avoid the parking hassle. The shuttle costs around $35 per person round trip.
What to Bring: Plenty of water (at least 3 liters per person), sturdy hiking shoes (waterproof if possible), insect repellent (mosquitoes are fierce), sunscreen, a hat, and a rain jacket (Kauai weather is unpredictable). Consider bringing trekking poles for added stability, especially on the descent.
Local Tip: Check the stream flow before you go. Heavy rains can make the stream crossings dangerous. The DLNR website and local news outlets often provide updates.
Awa’awapuhi Trail
For a truly unforgettable view, hike the Awa’awapuhi Trail. This 6.2-mile round trip trail leads to a dramatic viewpoint overlooking the Na Pali Coast with sheer cliffs dropping over 3,000 feet.
The Grind: The trail is mostly downhill on the way out (which means uphill on the way back – be prepared!). The path is well-maintained, but can be slippery if wet. The real challenge is the exposed nature of the viewpoint – if you’re afraid of heights, this might not be the trail for you.
How to Get There: The trailhead is located off Kokee Road (Highway 550) in Kokee State Park. Parking is available near the trailhead. Entry to Kokee State Park doesn’t have an entrance fee, but there is a small parking fee.
What to Bring: Water, sunscreen, a hat, and a camera (you’ll definitely want to capture the views!). Be sure to bring layers, as the weather in Kokee can be cooler and wetter than on the coast. Wind is also a factor at the viewpoint.
Local Tip: Arrive early (before 9 am) to avoid the crowds and increase your chances of clear views. Fog often rolls in later in the day.
Sleeping Giant (Nounou Mountain East Trail)
For a hike closer to town with panoramic views without too much difficulty, try the Sleeping Giant (Nounou Mountain East Trail). This 3.4-mile round trip hike near Kapaa leads to the “head” of the sleeping giant, providing stunning views of the coastline and the surrounding mountains.
The Grind: The trail is moderately strenuous, with a steady incline throughout. Parts of the trail can be steep and rocky. However, it is generally well-maintained and accessible to hikers of moderate fitness levels. There are picnic tables at the top, making it a great spot for a snack or lunch.
How to Get There: Take Highway 56 north from Lihue/airport, then turn onto Haleilio Road. The trailhead/parking area is located at the end of Haleilio Road at the base of the mountain. Parking can sometimes be limited, especially on weekends.
What to Bring: Water, sunscreen, a hat, and comfortable hiking shoes. The trail is mostly shaded, but sunscreen is still important.
Local Tip: This is a popular hike, especially on weekends. Go early in the morning or later in the afternoon to avoid congestion. The views at sunset are particularly spectacular; however, be aware that the trail is not well-lit, so bring a flashlight if you plan to hike down in the dark.
Kayaking Kauai: Paddle Power and Coastal Wonders
Beyond the trails, Kauai is equally impressive from the water. Kayaking is an excellent way to explore the island’s coastline, hidden beaches, and even venture up serene rivers.
Wailua River
The Wailua River is Kauai’s largest navigable river and a perfect spot for a leisurely kayaking adventure. It’s calm, scenic, and packed with cultural significance.
The Grind: This isn’t a strenuous paddle; it’s more about enjoying the scenery. It’s mostly flatwater paddling, suitable for beginners. The round trip to Fern Grotto and back is about 4 miles.
How to Get There & Cost: Numerous kayak rental companies operate along the Wailua River. Expect to pay around $40-$60 for a double kayak for a half-day rental. You can find rentals at the Wailua River State Park Launch Ramp.
What to Bring: Sunscreen, a hat, water shoes, a dry bag for your valuables, and plenty of water. Insect repellent is a good idea if you plan on hiking to Fern Grotto (more on that below).
Must-See: Paddle up to the Fern Grotto, a cave adorned with hanging ferns. While entering the grotto is no longer allowed due to safety concerns, you can still admire it from the water. Many tour operators also offer short guided walks through the surrounding rainforest.
Local Tip: The river can be crowded, especially during peak season. Consider going early in the morning or later in the afternoon to avoid the crowds.
Na Pali Coast Kayak Tour
For experienced kayakers, a guided Na Pali Coast kayak tour is the ultimate adventure. This is a full-day undertaking that requires physical fitness and a fair bit of paddling experience.
The Grind: This is a demanding physical activity, typically involving paddling for 15 miles or more in open ocean conditions. Swells can be significant, and the conditions can change rapidly. Not for the faint of heart. The usual entry point is at Haena Beach Park (permit required, see more below).
How to Get There & Cost: Numerous tour operators run Na Pali Coast kayak tours (e.g., Na Pali Kayak). Expect to pay around $200-$300 per person for a guided tour, including lunch and equipment. Tour operators handle all the logistics, including permits and transportation.
Permits and Safety: Keep in mind that permits are required for both kayaks and people if you are planning to land anywhere on the Napali Coast, or enter any of the sea caves. Also, the Na Pali Coast waters can be very dangerous, especially during the winter months.
What to Bring: Everything provided by the tour company (kayak, paddle, life vest), dry bag for your camera and valuables, sunscreen, a hat, sunglasses, and water shoes. Bring snacks to supplement the food and water provided by the tour operators.
Local Tip: Go during the summer months (May-September) when the ocean is generally calmer. Check the weather forecast and sea conditions before you go. Trust the tour operator’s assessment – if they cancel the tour due to unsafe conditions, don’t try to go on your own!
Hanalei River
The Hanalei River offers a more relaxed kayaking experience compared to the open ocean. It’s a scenic, gentle river that winds through lush taro fields and past the iconic Hanalei Bridge.
The Grind: A very easy paddle, suitable for beginner kayakers and families. The river is calm and shallow in most places.
How to Get There & Cost: You can rent kayaks from several outfitters in Hanalei town.Expect to pay around $30-$50 for a double kayak for a half-day rental. Several launch points are available along the river, including near the Hanalei Bridge and at the Hanalei Pier.
What to Bring: Sunscreen, a hat, water shoes, and a camera. The Hanalei River is known for its birdlife, so bring binoculars if you’re a birdwatcher.
Local Tip: Paddle upstream first to give yourself an easier ride back downstream. Take your time and enjoy the scenery – the Hanalei River is a peaceful and beautiful place.
Unforgettable Views: Where to Get Your ‘Gram On
Kauai is a photographer’s dream, with stunning vistas around every corner. Here are some of the best viewpoints to capture that perfect shot.
Waimea Canyon
Often called the “Grand Canyon of the Pacific,” Waimea Canyon is a geological marvel. The canyon stretches 14 miles long, 1 mile wide, and over 3,600 feet deep, offering breathtaking views of colorful cliffs, deep valleys, and cascading waterfalls.
How to Get There: Drive up Waimea Canyon Drive (Highway 550) from Waimea town. There are several overlooks along the way, each offering a unique perspective.
Best Viewpoints: Pu’u Hinahina Lookout and Waimea Canyon Lookout are the most popular and easily accessible. For a more panoramic view, hike the Canyon Trail to Waipo’o Falls (mentioned earlier).
Cost: There is no entrance fee for Waimea Canyon State Park, but there is a parking fee at certain overlooks. This is payable via card at a park kiosk.
Local Tip: Visit early in the morning or late in the afternoon for the best light. The canyon can be shrouded in mist during midday. Also be sure to check the weather conditions as it can change rapidly.
Hanalei Bay Lookout
This iconic viewpoint offers a sweeping panorama of Hanalei Bay, with its crescent-shaped beach, turquoise waters, and the backdrop of the majestic mountains. It’s one of the most photographed spots on Kauai.
How to Get There: The lookout is located along Kuhio Highway (Highway 56) just before entering Hanalei town from the south. It’s impossible to miss.
Best Time to Visit: Sunset is particularly beautiful, with the sun casting a golden glow over the bay. However, it can be crowded at this time of day.
Local Tip: There is a small pull-off area for parking, but it can fill up quickly. Be patient and wait for a spot to open up.
Kilauea Lighthouse
Perched on a dramatic cliff overlooking the Pacific Ocean, the Kilauea Lighthouse is not only a historic landmark but also a prime spot for wildlife viewing. It’s a National Wildlife Refuge, home to seabirds, including albatrosses, boobies, and frigatebirds.
How to Get There & Cost: Follow Kilauea Road from Kilauea town. There is an entrance fee of $10 per adult (children 15 and under are free). The lighthouse is open daily from 10:00 am to 4:00 pm.
What to See: The lighthouse itself is impressive, but the real attraction is the wildlife. Bring binoculars for a closer look at the birds. You might also spot Hawaiian monk seals and humpback whales (during the winter months).
Local Tip: Visit during the nesting season (November to July) for the best bird viewing opportunities. Arrive early to avoid the crowds.
Hidden Gems and Insider Secrets
Beyond the popular spots, Kauai has plenty of hidden gems waiting to be discovered.
Secret Beach (Kauapea Beach)
As the name suggests, Secret Beach is a bit of a challenge to find, but the reward is worth the effort. This secluded beach offers stunning views of the Kilauea Lighthouse and is a great spot for swimming, sunbathing, and snorkeling (when the conditions are calm).
How to Get There: From Kilauea Road, turn onto Kalihiwai Road. Follow it until you see a dirt parking lot on the left. A short, steep, and sometimes muddy trail leads down to the beach.
Local Tip: Be aware of strong currents and surf, especially during the winter months. This beach is not lifeguarded. Also, be respectful of the environment and pack out everything you pack in.
Spouting Horn Blowhole
On Kauai’s south shore, this natural wonder is a popular spot that draws many visitors. Here, ocean waves surge into an underwater lava tube, creating a geyser-like spout of water sometimes reaching heights of 50 to 60 feet. The force of the water rushing through the opening also creates a unique hissing or roaring sound.
How to Get There: Located on Lawai Road, about a 10-minute drive from Poipu. You can easily enter “Spouting Horn Blowhole” on your navigator to be taken to the location. Free ample parking available.
Local Tip: The height of the water spout is directly related to the wave action, so on days when the surf is higher, the spout is more impressive.
