Beautiful Hikes in Kauai, Hawaii

Mahaulepu Heritage Trail

One of the easiest hikes to complete on Kauai is the Mahaulepu Heritage Trail. With minimal elevation gain, the trek is more akin to a beautiful coastal stroll. Starting at Shipwreck Beach trek along the memorable limestone cliffs, pass kiawe trees before reaching the Makauwahi caves. Spot more fossilized marine life hidden among the lush foliage.

The initial trek ends at Mahaulepu Beach, a remote part of the island’s southern shoreline. Isolated and fragile, enjoy the beautiful scenes before softly wandering back to the trailhead.

Sleeping Giant Trail (Nounou Mountain)

Trekking along the ridgeline of Nounou Mountain Trail is one of the best hikes in Kauai. Local legend tells the tale of a giant who feasted at a celebration in his name before drifting off to eternal sleep. Naturally, the epic ridgeline resembles the outline of the sleeping giant and can be seen from various parts of the island. To start, the hike guides you through an immense plantation of trees, before the switchbacks take you up the ridge.

These trees were planted in unison in the 1930s by the Civilian Conservation Corps and have grown into giants themselves. Once you’re above the treeline, you can see forever. The ridgeline plateaus offering exciting hiking to match the spectacular views. Arrive before sunset to capture the golden hour from above!

Kalalau Trail

If you only have time to do one full day hike on Kauai Island, then why not do the best one? The Kalalau Trail is an epic adventure suited to more advanced hikers and can be split into a multi-day trip. Beginning at Ke’e Beach, the trail winds along the vast Na Pali Coast and eleven miles along you’ll arrive at the remote Kalalau Beach. The secluded spot rewards gorgeous views and the best spot to camp anywhere on the island.

Stay for a night or two before completing the return journey back to Ke’e Beach. The trail’s length, along with some treacherous terrain, has not stopped it from becoming one of the most popular hikes in Kauai. In fact, you’ll need to apply for a permit before setting off. We recommend applying around 4 months in advance.

Speaking of amazing hikes, Oahu has its fair share. You can read all about them here.

Waipo’o Falls Trail (Waimea Canyon Trail)

Before beginning this hike, it’s best to check your expectation at the door. The Waipo’o Falls Trail is some of the best Kauai hiking, but not for the reasons you’d expect. The view towards the aforementioned falls is limited on this trek. In fact, the trail leads you to the top of them.

That may lead to an anti-climax for many hikers, but not for you. Because you’re doing this hike to see the stunning views of Waimea Canyon. Often compared to the Grand Canyon, textures, colors and rock patterns of the Waimea canyon promise to blow you away.

There are several quick detours that grant exceptional views, but the main trail leads to a vast stretch of rock that overlooks a hair-raising drop into Waimea Canyon. The hike attracts decent crowds because of easy access and the brief trip.

Kuilau Ridge Trail

If you’re after short yet adventurous day hikes in Kauai, then consider trekking the Kuilau Ridge Trail. From the Keahua Arboretum hikers have the built-in advantage of beginning at elevation. So, from the first step, you’re rewarded with instant views.

Like a lot of trails of Kauai, the path can be muddy, especially after rain. This can make the trail a little hard to follow at times. However, any navigational struggles are worth it as you wander through ancient forests with views of far-off mountain ranges. The trail doesn’t lead to an epic completion, with the journey here being more spectacular than the destination. But the trail is accessible and can be completed by young and old. Making for a perfect family day out.

Kalepa Ridge Trail

Short and sweet but epic nonetheless, Kalepa Ridge is one of the most adrenalin pumping hiking trails on the island. Depending on the weather, this trail can vary from moderate to difficult. The narrow path follows gnarly terrain and can often be uncertain underfoot. The Kalepa Ridge Trail is an unofficial trek, so it sees less foot traffic than other Kauai hiking trails. You will need to feel confident hiking in a more remote part of the state park.

After the trail starts, follow the ridge formation as the views clear and the natural beauty becomes ever more apparent. The ridge offers views of the most iconic part of the Na Pali coastline, the Kalalau Valley. Come here for sunset to enjoy the colorful sky with just your friends and family.

Nualolo Ridge Trail

If your hike along the Honopu Ridge Trail wasn’t hard enough on your legs, then challenge yourself on Nualolo Ridge Trail. One of the toughest Kauai hikes begins with a sharp descent with even greater views of the Na Pali Coast. The issue? Well, muddy downhill trails through the rainforest are tough on your legs, but along the way you’ll stumble upon several incredible views. Stop here to appreciate the vibrant colors and rest your weary limbs.

Soon rugged meadows take over, opening up the world around you. You may even spot the elusive I’iwi honeycreeper. The difficulty of the hike scares off many potential trekkers, leaving you to enjoy the paradise in peace. Once you’ve reached the end of the downhill, all that’s left is the walk back up!

Okolehao Trail

Switching our attention to Kauai’s north shore, this trek is a hiking trail that will give you one heck of a workout. Muddy and not always well signposted, the Okolehao Trail helps you forget the struggle with picturesque views of Hanalei Bay, the valley and the historic Kilauea Lighthouse.

The hiking trail begins in dense forests before the trees depart, leaving behind taro meadows and the chance to see further afield. The sharp climb is roughly 2.5 miles in length and at times you’ll need to make use of the chains to keep your footing.

Honopu Ridge Trail

An unforgettable way to experience the stunning Na Pali Coast is on the Honopu Ridge Trail. The five-mile out and back hike comes with amazing coastal views along with the chance to see the mountains shoot out of the Pacific Ocean up close. The trick here is to complete the hike on a clear day. While the trail is always fun, the amazing views can easily be covered by wandering clouds. The thin trail is well marked and guides you along the breathtaking coast with dramatic drop offs to one side.

The one drawback of this hike is the shrubs and branches that live along the narrow trail. If you can, bring along some trousers or leggings to avoid scratches en masse. From the first viewpoint, you’ll gaze upon the beautiful Honopu Valley Waterfall. The second viewpoint offers long-range vistas as far as Nualolo Ridge.

Makawehi Lithified Cliffs Trail

After exploring some of the epic adventures to be had on Kauai hiking trails, let’s change tack for a minute. Hiking the Makawehi Lithified Cliffs is less a trek and more of an excursion back in time.

The extraordinary cliffs on the east end of Shipwreck Beach are made from sand dunes, slowly compacted by soaring winds and surf breaks over a millennia. The result is spectacular rock caverns, diverse colours and several fossilized fish and other marine life. One of the most popular hikes on Kaui for people of all ages, take the time to appreciate the history on display. But don’t forget to look up and enjoy the southern views along the sea cliffs.

Awaawapuhi Trail

The iconic Awaawapuhi Trail is rated as one of the best hiking trails on Kauai for an all-day adventure. Like a lot of Kauai hiking trails, you’ll follow a ridgeline with continuous views of the Na Pali Coast. After around 90 minutes of awe-inspiring and downhill hiking, the trek culminates at the official viewpoint. With stark drop-offs on either side, the ridge ends with a postcard-worthy view.

You can continue to venture down but will have to do so off-trail and the crumbling path can be difficult to navigate. On the return journey, take your mind off the thigh-burning climb on the Awaawapuhi trail with views towards the engulfing mountains on either side.

Makaleha Falls Trail

One of the great hikes in Kauai, the Makaleha Falls hike, will be remembered as much for the mud as the waterfalls. The hiking trail follows the Makaleha Stream for its entirety, with several water crossings on your journey.

The spectacular falls may tempt people of all abilities to try the hike, but it’s rated difficult for a reason. Expect some sections of bouldering mossy rocks and ducking through aimless branches, all the while trying to keep track of the actual path. Eventually you’ll spot the mesmerizing two-tiered falls. There is a spot for cliff jumping and you can continue on to Hidden Falls.

Hanakapiai Falls Trail

If you hiked the Kalalau Trail, you’ll also begin the trek towards Hanankapiai Falls. For those that didn’t get a permit to complete Kalalau, you can still trek the full Hanakapiai Falls Trail, which is a wonderful alternative.

After following the spellbinding north shore coastline and Hanakapiai Beach, cut inland to capture the 300ft waterfall surrounded by dense jungle. The hike to the falls is a climb that doesn’t let up, with the steep incline and tree roots being your biggest nemeses. But the Hanakapiai Falls are one of the best on the island, the turquoise waters contrast with the dense green jungle surrounds. While they’ll also reward you with a refreshing tumbling shower.

Alaka’i Swamp Trail

One of the most unique Kauai hiking trails is Alaka’i Swamp. AKA an alpine swamp, the trail helps show off the many fascinating plants and animals that exist in the island’s high altitude regions. Although the trail follows a raised boardwalk, don’t think you’re going to come out of this clean. Starting at the lookout, continue on the Pihea Trail for gorgeous views of the Kalalau Valley.

The boardwalks will soon take over and guide you through monstrous hapu’u ferns before ending at the Kilohana Lookout. Complete the interesting experience with vistas of Hanalei Bay.

Kauapea Beach (Secret Beach)

The initial steep descent may be fun for type two hikers, but that’s not why the hike to Kauapea Beach has made this list. Here, the destination is more important than the journey. The hike simply delivers a remote and beautiful scenery to you on a silver platter.

Secret Beach is spacious, with soft sand that dances between your toes. The backdrop of greens, browns and ocean mist is like a view from a fairytale. Explore the tidal pools, or if the ocean is calm, enjoy a swim.

Ho’opi’i Falls Trail

For action-packed day hikes on Kauai hiking trails, then don’t pass up the trek to Ho’opi’i Falls. The short two-mile trek to the falls is packed with adventure. Along the way, you’ll pass two falls, the first offering magnificent spots for cliff jumping. The second waterfall is the main attraction and was a filming location in Jurassic Park.

The trail is surrounded by soaring jungle that envelopes you in every direction. But in those two spots, they disperse, opening up a magical world. Ho’opo’i Falls features a large swimming hole for a well-earned dip.
