Waimea Canyon State Park

There’s no shortage of epic scenery in Kauai, but Waimea Canyon State Park promises to be among the most memorable for travelers visiting this beautiful Hawaiian island. A mix of lush greens and dense oranges, the canyon will leave you in awe as you gaze upon it.

Waimea Canyon State Park

There’s a reason Waimea Canyon is known as the Grand Canyon of the Pacific. Its deep valleys cut through the rugged mountains for 14 miles, 3,600 feet below the tallest peak. Several jaw-dropping waterfalls dot the rich cliffside, tumbling endlessly down the canyon.

There are several ways to explore Waimea Canyon State Park. You can appreciate the spectacular scenery from one of the many viewpoints along the epic Kok’e Road. But for the adventurers among us, head out on the 2-mile Cliff Trail that takes you to the edge of the canyon.

Poipu Beach Park

On Kauai’s sun-soaked southern coast, Poipu Beach Park is one of the island’s coolest places to see. Reward yourself with a true Hawaiian experience as you laze upon the golden sand shores, with turquoise water lapping at your feet.

Poipu Beach Park

Once home to sugar plantations, the land around the beach is now home to large luxury resorts, making use of the exquisite location. The popular South Shore beach offers exceptional scenery while remaining close to restaurants, attractions, and some of the best places to stay on Kauai.

The off-shore sand bar and lack of swell make Poipu Beach one of the most popular beaches on Kauai for families and young kids. Enjoy pleasant swimming with the chance to spot humpback whales in the distance between December and May.

Hanalei Bay

The quaint coastal town of Hanalei is blessed with the biggest bay in Kauai: Hanalei Bay. The powder-like sand coats the edges of town. At Hanalei Bay, surf culture, farmers markets, and a backdrop of dense green mountains create a wonderful place to visit.

Hanalei Bay Beach

Hanalei Bay features three pristine beaches: Hanalei Beach Park, Black Pot Beach, and Waioli Beach Park. They all blend into each other and are more noted for their great surf breaks than for swimming. Along the bay, you’ll also find the mouth of the Hanalei River and the historic pier.

Rows of waterfront restaurants and bars are set just back from the beaches. Aside from surfing, paddleboarding, kayaking, and smaller catamarans are great ways to explore the expansive bay.

PRO TIP: Along with nearby Princeville, Hanalei is one of the best places to stay in Kauai. This area on the North Shore is home to many of the island’s top hotels, resorts, and vacation rentals. You’ll also find a handful of good accommodation options on the South Shore near Poipu.

Wailua River State Park

Speaking of great places to kayak, Wailua River State Park is home to the island’s only river you can explore on a kayak adventure. Meandering through 20 miles of lush jungle, kayakers will pass epic waterfalls, including the 80-foot Wailua Falls, along with ancient Hawaiian temples otherwise known as heiau.

Wailua River State Park

Although it’s an epic adventure, you don’t need to have any prior experience to make your way down the Wailua River. In fact, you can jump on a kayak with an outrigger for more support while your guide will ensure you’re ready for the journey.

If you aren’t up for a kayak, you can drive to a viewpoint of Wailua Falls and Opaekaa Falls. Before heading out, pay a visit to the Wailua Complex of Heiau to explore the National Historic Landmark, with petroglyphs, ruins, and birthstones.

Shipwreck Beach

Around the corner from Poipu is the rocky and aptly-called Shipwreck Beach. Much time may have passed since the beach earned its name after a wooden ship sunk off-shore. But its craggy cliffs will evoke plenty of images.

Shipwreck Beach

Sitting on Kauai’s South Shore, Shipwreck Beach has a large open shoreline with ample room to spread out on the golden sand. The beach’s reef break doesn’t make for the best swimming. Arm yourself with either a boogie or surfboard to make the most of the rolling waves.

To the edge of the South Shore beach, you’ll spot visitors jumping off the 40-foot cliff into the water below. Join if you wish, but the swim back can be choppy.

Wailua Falls

If you forgo the kayak trip down the river, make sure you still arrive at one of the highlights of Kauai: Wailua Falls. A winding road will take you through the mountainous jungle to a viewpoint where you can see the falls in their full glory.

Wailua Falls

A stunning body of water, Wailua Falls juts out off the edge of the cliff in two parts, tumbling 80 feet into the pool below. It’s been said that Hawaiian chiefs would jump from the cliff to showcase their courage.

The soaring white mist flies back up, creating endless rainbows and adding more colors to the vibrant landscape. There’s an unofficial trail down to the pools, but it’s not maintained. In true Hawaiian fashion, it’s also very slippery.

Kalalau Trail

If you like adventure and are wondering what to do in Kauai, the Kalalau Trail is your answer. Traversing the edge of the spellbinding Na Pali Coast, the 11-mile hiking trail is not for the faint of heart. One of the top hiking trails on Kauai, it’s a veritable journey through the beautiful but unforgiving landscape in the Kalalau Valley.

Kalalau Trail

Most join the trail from Ke’e Beach and walk two miles to the gorgeous Hanakapiai Beach. Those who venture beyond will need overnight gear and a hiking permit.

While the trail may only be 11 miles, there’s no exit at the end. Instead, you’ll camp behind Kalalau Beach, reveling in the amazing memories made. 

Tunnels Beach

One of the best places to go snorkeling in Kauai is Tunnels Beach. With limited parking, be sure to arrive early at this popular North Shore beach. After diving into the crystal clear water, you’ll explore the reef that spreads out in each direction. Among them are intricate tunnels and caves where vibrant sea life roams.

Tunnels Beach

As you swim at Tunnels Beach, keep your eye out for green sea turtles and even the rare Hawaiian monk seal. Snorkelers can swim relaxed thanks to the beach’s lifeguards, who will keep a keen eye on the swimming conditions. Tunnels Beach has an inner reef for newbies and a brilliant outer reef, home to sea cliffs but stronger currents.

Those who stay onshore can admire the monstrous peaks to the west, the soft white sand, and the calming water.

Secret Falls

Located in Wailua River State Park, Secret Falls is another majestic waterfall that encapsulates the true beauty of Kauai. Secret Falls, also known as Uluwehi Falls, is no longer much of a secret. But its hard-to-reach location means you’ll have the opportunity to enjoy the cascading falls away from the crowds.

Secret Falls

The only way to reach Secret Falls is along the Wailua River. Unless you’ve become pals with a local, you’ll likely have to sign up for a guided kayak tour. The journey itself is worth the price of admission on its own. Enjoy spectacular views of the Sleeping Giant (Nounou Mountain) and Fern Grotto.

On arrival, gaze upon the stunning falls, dropping 100 feet into the swimming hole below.

Secret Beach

Sitting on Kauai’s North Shore, Secret Beach remains tucked away from sight and requires a steep downhill hike to arrive on its golden shores. Also known as Kaupea Beach, the stretch of sand lets you enjoy the privacy provided by the backdrop of the rugged cliffs with ample room to spread out.

Secret Beach

Minutes from the coastal town of Kilauea, Secret Beach remains relatively calm in the summer months. However, come winter, the swell picks up, and the currents show their might. Locals flock to Secret Beach with their boards and put on an exciting show for onlookers as they try to tame the burly surf.

Anini Beach

As one of the most kid-friendly beaches on the island, Anini Beach has long been a hit with families. Although on the North Shore, you can expect protected swimming all year long thanks to the off-shore reef.

Anini Beach

Spanning much of Anini Beach’s two-mile shoreline, the waves are minimal, with plenty of shallow water to wade in. Besides the calm swimming conditions, all visitors can make use of the range of on-site amenities. These include bathrooms, showers, and picnic tables for a nice shaded lunch.

To make the most of the experience, you can rent snorkel gear at the beach and explore the beautiful coral.

Koke’e State Park

As one of the top tourist attractions in Kauai, leave plenty of room on the itinerary for Koke’e State Park. The park is next door to Waimea Canyon and features the deepest part of the canyon.  

Koke'e State Park

While you’ll see plenty of red sandstone cliffs in Waimea Canyon, the landscape quickly changes. Koke’e State Park is flooded in thick rainforests, where the temperature rapidly drops as you gain elevation.

You can easily drive through the park and stop at amazing viewpoints, including Pu’u Kila Lookout, where you can gaze upon the mesmerizing cliffs along the Na Pali Coast. To explore the rainforest, trek along the 3.5-mile Alakai Swamp Trail.

Sleeping Giant (Nounou Mountain)

On your way to Secret Falls, you’ll bask in long-range views of the Sleeping Giant. If you’ve been inspired to hike to the top, you’ll be happy to know there are three ways to arrive at the summit of the Sleeping Giant, also known as Nounou Mountain.

Sleeping Giant

The most direct Sleeping Giant Trail is the East Trail. The trail is 1.75 miles one way but has a sharp elevation gain. The most popular hiking trail is the West Trail, clocking in at 3.8 miles return. Departing from the end of Lokelani Road, you’ll head through the yellow gate and be immediately surrounded by gorgeous forest.

Scramble over rock outcroppings for vast vistas on your way to a protected picnic area near the top. Enjoy a break with panoramic views of the countryside and the Pacific Ocean before basking in even better views on the summit.

Queen’s Bath

Just outside of the popular resort town of Princeville on the North Shore, Queen’s Bath is a stunning tide pool enveloped in burnt lava rock. In years past, Hawaiian royalty would bathe right here and soak up its sacred waters.

Queen’s Bath

Along the edge of the Queen’s Bath is a small cliff where multiple falls provide fresh mountain water as the pool rises and falls with the ocean. Many visitors to the spectacular location remain away from the water and cliff as the surging waves can be quite dangerous and the conditions volatile.

If you choose to head into the water, remain vigilant, wear sturdy shoes, and keep an eye out for large waves.

Na Pali Coast

You can experience the jaw-dropping Na Pali Coast in a manner of ways. Whether it’s on the aforementioned Kalalau Trail or a dinner cruise as you caress the spectacular coastline, there’s no right or wrong way. But the 17-mile coast, teeming with cathedral cliffs and plummeting falls, is the most picturesque part of Kauai.

Na Pali Coast on Kauai

For some, the region will feel familiar as it featured plenty in the iconic film Jurassic Park. Na Pali Coast remains untouched by time thanks to its soaring peaks and narrow valleys that act as iron shields.

Aside from cruises and hikes, you can kayak along the coast to explore sea caves and quiet beaches. Or even take a helicopter tour to the otherwise inaccessible Manawaiopuna Falls.

Polihale State Park

Speaking of remote, on the edge of Na Pali Coast lies Polihale State Park. The road to the beach is unpaved—and many rental cars aren’t allowed to make the 5-mile journey. Those who do make it, whether on foot or in a car, will immediately be rewarded with an untouched paradise and 17 miles of bright white sand.

Polihale Beach State Park

With the emerald-hued Makaha Ridge providing the immediate backdrop with long-range views of the knife’s edge of the Na Pali cliffs, you could spend all afternoon admiring your surroundings.

The swimming here can be rough, and there are no lifeguards. But with space to spread out and overnight beach camping allowed, simply kick back and enjoy the show.

Mount Waialeale

Known as the “wettest spot on earth,” Mount Waialeale is a weeping landscape that receives 450 inches of rain on average every year. It’s no wonder Waialeale translates to overflowing water.

Mount Waialeale

Endless waterfalls drape down the side of the mountain, carving their way through the dense rainforest and lush greenery that’s never left thirsty. Seeing the 5,148-foot summit is tricky, as clouds gather around its peak, often refusing to disperse.

You can hike around the eastern edge of Mount Waialeale on two hikes, including a 5-mile trek to Blue Hole, presenting you with an unforgettable “weeping wall.”
