Kauai is often the forgotten cousin of the larger Hawaiian islands, that idyllic archipelago worth visiting any time of year. Travelers may seek the endless sun of the Big Island, the incredible scenery of a road trip in Maui, and the history and excitement of Oahu. Yet they do so while overlooking the northernmost island in the Hawaiian chain: wet, sleepy Kauai.

Yet the very same qualities that make Kauai less attractive to some are ones that we think make it the perfect location for travelers who want a less polished, less tourist-laden experience. Travelers will find a variety of outdoor options on each island, but Kauai is packed with things to do. It’s also now going to be even easier to fly to. These are the unexpected reasons why Kauai is the most underrated island in Hawaii.

1. It rains a lot.

It rains at least fifteen days a month in Kauai towns like Hanalei and Poipu. That’s twice the days of rain you’ll get on the west side of the Big Island.

Of course, rain isn’t normally a desirable thing for people seeking a vacation island. And admittedly, the precipitation up north can occasionally last all day and churn up Hanalei Bay with brown river water. But those days are the exceptions. Most of the time, warm drizzle is interspersed with brilliant sunshine, and you can usually drive around the island to find dryer weather. The rain clouds are often so localized that you feel raindrops and sunshine at the same time — which makes for glorious rainbows.

The reason we love the wet weather — besides all those rainbows — is that it makes Kauai incredibly lush. After all, it is called the “Garden Isle.” The other, snarkier reason we appreciate the rainfall is because other people don’t. As long as Kauai remains the rainy isle, it will keep away a fair amount of sunseekers — leaving its sandy beaches for the rest of us.

2. It’s dangerous.

We don’t mean to be flippant. Enough people have lost their lives in Hawaiian waters that the state has taken to running videos with stark warnings of ocean dangers at airport baggage claims. We agree that the power of the ocean should be respected, but we love that Kauai has a wild edge to it.

Unlike Oahu and Maui, no highway circumnavigates the island. If Kauai were a clock, time would go from noon to 9:00 PM and stop there. In the space from 9:00 PM to midnight, the otherworldly Na Pali cliffs are too steep and treacherous for a roadway. The only way to see them is to hike in, kayak to their shores, or view them from a helicopter.

Both ends of Kauai’s coastal highway are also pretty intimidating. On the west end, the dirt road to Polihale State Park gets filled with such large pools of water after a storm that you could get stuck — and there’s no cell service out there. On the north side, the highway past Hanalei is currently closed. with the full reopening expected some time over the 2019 summer. Much of it was destroyed during the April 2018 flooding that affected the area. Previously, you would just drive through the rivers of water that gushed across the road in rainy weather. We expect the rebuilt road to require a little less nerve to traverse.

It’s not just the roads and Na Pali cliffs that are scary but the ocean itself. Kauai is home to some of Hawaii’s most hardcore surfers, and plenty of surf spots there are not for the meek. Waiohai at Poipu is a sea-urchin minefield at low tide while seemingly gentle Pakalas is mud-brown, sharky, and, frankly, not that friendly to newcomers. And while the pre-teen locals tearing up the surf by the Beach House are making those waves look easy, don’t be fooled. They’re challenging. But these pros-only waves also make for some of the most epic viewing experiences from the beach.

3. The best beaches are hard to get to.

Families weighted down with beach umbrellas, coolers, chairs, and the like are not looking for hard-to-reach shores. And that’s a good thing — because there are plenty of lesser known beaches for the rest of us to enjoy.

At the north end of the island, in Princeville, a nine-car lot is the only place to park your car if you want to access Hideaways Beach. You may have to hang out in your car until a space opens up. Then a ridiculously steep and treacherous path down the escarpment — with rusted posts, uneven steps, and haphazard ropes stretched across slippery rocks — brings you to Hideaways, a jungly gem of a beach cove. The foliage is so dense here that you wouldn’t need a beach umbrella, anyway.

On the south shore, by McBryde and Allerton Gardens where botanical tours are available, you need to park along the road and scamper along a retaining wall to get past the locked gate. Then you’ll keep walking along an overgrown path, ducking under very low branches. Eventually, you’ll reach Ka Lea O Kaiwa Beach, another lovely, sandy nook. The only thing you may want to bring there are boogie boards, but be careful. The waves are fast and steep.

Or you can drive past the Grand Hyatt where the paving gives way to dirt, past the horse stables. At some point, your brain will be rattling from the rutted road, and you’ll become convinced you are lost. Only then will you see a car or two parked next to some trees. This is Gillin’s parking lot. Park, put on your flip-flops (they call these slippers in Kauai), and find a trail through the trees. You’ll be rewarded with a white-sand sliver of a beach and very few people.

4. You can snack on spam.

Once upon a time, poke was an adventurous food, one you only tried if someone else who’d been to the islands told you where to get it on your own trip to Hawaii. Now it’s gone mainstream.

The fact is that Hawaiians are always onto something, and it’s not when they coat mahi-mahi in a thick layer of crushed macadamias and serve it to you at a resort restaurant. It’s when they prepare their own cuisine, which is an intoxicating meld of so many different cultures — Korean, Japanese, Chinese, Portuguese, and others. If you can get off the beaten path and find those foods, you’re in for a treat.

Kauai is also a great place to get off that well-worn path. You could stop at the Salt Pond Country Store on your way back from Waimea Canyon. Get there by early afternoon on a weekend day and they won’t be sold out of the spam musubi, which is basically like a sushi roll with spam (a Hawaiian delicacy) inside. Unlike some of the other prepared foods, the spam musubi isn’t refrigerated. It sits on the counter, and it’s oddly satisfying. It’s also a great way to discover Hawaiian’s obsession with spam, long before it became retro cool.

If you’re staying in a condo or house with a grill, go to the Big Save Market in Old Koloa Town and ask the lady at the meat counter for the bright red marinated chicken thighs or spicy short ribs stashed in the back. These are normally set aside for locals. She’ll be impressed. In Princeville, hit up the North Shore General Store behind the Chevron station and preorder some grass-fed steaks from nearby ranches.

5. You can drink your breakfast — or lunch.

If you’re driving along the Kuhio Highway by Anahola, an area where locals with Hawaiian ancestry can find housing at more reasonable prices, don’t just admire that cute orange shack nestled in the trees. Slow down and turn into the parking area of the Kalalea Juice Hale. The One Speed — a luscious whirl of coffee, bananas, house-made coconut milk, dates, and cocoa nibs — is better than a venti latte any day.

You’ll find amazing juice shops all over the island. The Kauai Juice Co. has three stores, and among its uber-healthy juices and energy shots is the Selfie, made with celery, cukes, kale, chard, parsley, turmeric, ginger, garlic, cider vinegar, and chili pepper. Essentially, it’s a liquid salad. You can also get smoothies at Hanalei’s Aloha Juice Bar, the all-natural Harvest Market or Living Foods Market, and the Little Fish coffee kiosk in Poipu. With fruit as good as you can get in Kauai, why wouldn’t you drink your meal?

6. You don’t actually need to be a surfer.

You don’t need to be a surfer to enjoy Hawaii’s waters. At Ka Lea O Kaiwa beach, you might see some heart-stopping boogie boarders. Local teens seek out the tightest barrels, getting in deep and letting the barrels spin them upside down like they’re in a rinse cycle as they zip down the line — before getting crushed by the close-out. Then they go back for more.

Those guys have grown up doing this. Don’t try it. You can, however, boogie board in calmer seas at Poipu or hit up the sand-bottom swells at Hanalei Bay. You can also snorkel in a few locations — the best spot is by the Beach House Restaurant. You can rent snorkel gear for $5 an hour right from Boss Frog’s, steps away from the snorkel spot.

You can also sea kayak to check out the Na Pali cliffs or kayak down the Hanalei River towards the bay. There’s some incredibly fun zip lining to be had, as well. Golf clubs abound in Kauai, including the Princeville Makai Golf Club, one of the top public courses in the country. And, of course, the hiking is fantastic. Besides the Na Pali coast, a great trail on the south side starts at Shipwreck Beach.

7. You can ride a bike.

You can mountain bike, and Kauai does have a few mountainside single-track options. But what we love is riding those uncomplicated, single-speed beach cruisers along Kauai’s eastern shore. You can rent bikes for just $5 an hour or $15 all day. They come with either baskets or cute little bags for your goodies tied onto the handlebars.

Then, pedal out towards the beach where you’ll find a paved road alongside it. Head due north. You’ll have the ocean on your right the whole way north, and you’ll pass a few ideal spots to take pictures or grab a covered picnic table to have a snack. You may see locals jogging or walking, as well. The six-mile round-trip journey will take you to Donkey Beach where you can jump in for a dip. It’s an easygoing excursion in a very Kauai sort of way.

8. There aren’t a lot of big resorts.

This isn’t wholly accurate; there is, in fact, a Sheraton, a Marriott, and a few other big chain hotels. It’s just that you don’t feel their presence as much as you would in, say, the Big Island’s Kona-Kailua coast or Maui’s Wailea area. And on the north shore of Hawaii, you’ve only got the St. Regis at Princeville. While Hawaiian island cruise ships do come into Kauai, they embark in Nawiliwili, close to the Lihue airport and nowhere near the scenic places you’re likely to stay.

This means you won’t find yourself fighting resort-goers for a spot on the sand as there are miles of other shoreline stretches to choose from. Instead of staying at a hotel, you can rent a condo or splurge with a bigger group and rent a house in Hanalei.

Also, the resorts that do exist in Kauai are, for the most part, more low-key than you might find on the other islands. Sure, the Grand Hyatt Kauai has an opulent lobby, and its Tide Pool restaurant — which sits atop the water and with a cheesy thatched roof — is too much. But the evening Hawaiian performance has a homey quality to it and has been performed by some of the same musicians and dancers for years. On a recent Tuesday, the young Hawaiian boy lighting the torch and blowing the conch shell was being watched by his proud grandparents.

9. It has a few superlatives of its own.

We love Kauai’s low-key vibe. You won’t find fancy shopping here. The shops in Hanalei Bay are inexpensive and have a Bohemian, surfer flair. Restaurants like the Mermaids Cafe, which serves hearty wraps to be eaten at picnic benches next to a brightly hued mural, exemplify Kauai’s chill style. The few exceptions serving tasty, fancier fare include Hanalei’s small-plates specialist Bar Acuda.

But Kauai has a few places where it tops the other isles. Kauai is the oldest island in the Hawaiian chain, located north of its cousins. If you look at a map, you’ll see that Kauai is actually farther from the other islands than they are from each other. Kauai, in a way, is set apart.

It’s also the greenest of all the Hawaiian islands, and 97 percent of it is covered by forests or mountain ranges. It has the most dramatic landscape in its 4,000-foot-high Na Pali cliffs. And it has the biggest gorge in the Pacific, the ten-mile-long and 3,000-foot-deep Waimea Canyon.

And with all that rainfall, we venture to guess Kauai has the most rainbows, too.
