20 Things to know before visiting Kauai

First Time on Kauai?

The fourth largest island in the Hawaiian chain, Kauai tops popular charts of the best vacation places in the USA and the world. Widely acclaimed as “The Garden Island“, this tropical destination is a dream come true for anybody looking for a laid-back, relaxed time-off.

Soak up the sun on a beach, ride a bike, or go for a hike, accompanied by breathtaking vistas, explore small towns of the island, or venture to awe-striking waterfalls – the choices are all yours. But to reap full benefits of the time spent on the island, make sure to check out these 20 things that will tell you what to do and how to do it when on Kauai. With a little preparation, you will feel at home on the Garden Island and even be able to avoid some inconvenient and unpleasant situations.



1. 75% of the island is uninhabited

Due to impassable rainforest and gigantic mountains, the majority of the islanders settle on the shore, occupying roughly 25% of the territory of Kauai. The remaining 75% of the island belongs to the forbidden kingdom of exotic Hawaiian creatures and is inaccessible on foot.

2. Over 50% of Kauai’s coastline are beaches

With this data, you can hardly argue about the island claiming its spot among the best vacation destinations in the world. However, the sandy beaches do not automatically imply the abundance of swimming area. For example, dominated by deadly surfs, strong currents, and dangerous riptides, most of the north shore, including such places as the Queen’s Bath, is out of questions in the colder months.

3. Perfect weather year round

Kauai is one of a few places on earth that can boast the perfect vacation weather. With the average temperature ranging between 75 and 85 degrees Fahrenheit, this Hawaiian island allures the vacationers from all over the world at any time and season.

4. Equally ideal ocean temperature

The island might have some swimming issues, however, the ocean temperature completely compensates for such troubles. Perfect for professional surfers, scuba divers, and amateur swimmers alike, the temperature barely goes beyond 60 and exceeds 80 degrees Fahrenheit.

5. The second rainiest place on Earth

Located in the heart of Kauai, Mount Waialeale is considered the second wettest place in the world. With the sky dropping its rainy tears 365 days of the year, Kauai is indeed one of the rainiest places on earth, surpassed only by Mawsynram, a small village in northeastern India.


6. Renting a car is a must

Even though the island is pretty small, you need a car to get around and find Kauai’s spectacular sites and hidden gems.

7. U-shaped road

On that note, an important thing to know about Kauai to prepare for your best vacation is that there is no road connection between northern and southern parts of the island. As a result, such pristine, yet inaccessible by car areas as the Na Pali coastline and Waimea Canyon are better to be conquered on foot.

Still, succumbing to the convenience and speed of the car, you can use the only major road, shaped in the form of the letter “U”, and explore the island along its both branches. To get a better picture, starting from Lihue (the capital city), it takes approximately one hour to get to the end of each side of the road.

8. One-lane bridge rule

Technically speaking, it is not exactly a rule, but rather a custom and respect toward other fellow-drivers. The main road on the north shore of the island has a few one-lane bridges. Typically, you let a small batch of cars consisting of approximately five to seven automobiles go one way at a time. If you are happened to end up outside of this batch, stop and let the cars on the opposite side pass by before resuming your journey.


9. Comfortable and casual clothes over formal attires

The reigning queen of simplicity and countryside lifestyle, Kauai lacks all demands for glamorous clothes and expensive jewelry. Keep it easy and casual. Therefore, t-shirts, flip-flops, and a good pair of shorts will serve you well… pretty much everywhere on the island.

10. Prices are much higher

This applies to everything. It might not come as a big surprise, considering that almost everything has to be shipped in. So despite the fact that Kauai is still a territory of the USA, the prices here are much higher compared to other states. On the bright side, the Garden Island has plenty of bargain stores to keep your travels within your budget.

11. Tropical fruits… pick and eat them

You are in Hawaii, for goodness sake, one the best places to grow tropical fruits. And no, you do not always have to pay for them here. The rule is simple: you see the fruit, pick it, and eat it. However, I have a simple word of advice for you, make sure you don’t trespass on private property and steal the fruits.

12. All dietary restrictions are accommodated

Not exactly the topic about the tropical fruits as the subheading suggests, but it’s definitely worth mentioning here. When on Kauai, forget about difficulties you might have with finding the best food options for your dietary restrictions. Exploring such options as Hawaiian barbecue, Tai and Indian cuisines, or small restaurant with variety of vegetarian and vegan options, you will not stay hungry here, for sure.

I simply cannot move on to our next thing to know about Kauai without giving some praise to The Greenery Café. A family operated restaurant in the center of Lihue is a real gourmand paradise. Their signature fish and chicken wraps, hummus and kale salads, coconut-ginger mug bean soup, avocado wrap (my favorite), smoothies and juices – and remember everything is organic – are out of this world. You will not be able to resist the temptation.

However, no good things can go without a single downside. Since only a handful of people work at the restaurant, which popularity increases exponentially, the wait time might be long. (We had to wait for almost an hour for our orders.) The best way to avoid such inconveniences is to order beforehand over the phone. By the time you reach The Greenery Café, your food will be ready for you to pick up. You can take it out or enjoy in the backyard of the restaurant.


13. Nene goose is the official state bird

Not as glamorous as you might think for this tropical area… But yes, the Nene Goose is the official bird of the state of Hawaii with Kauai having their largest protected population.

14. Chicken is the unofficial bird of Kauai

The chickens run wild on Kauai. Be ready to see a lot of them and absolutely EVERYWHERE from the airport to gas stations, parks, streets, and even hotel lobbies…

15. Wild pigs are common

In fact, they are considered the island’s second most popular inhabitants, after the chickens, of course. Running wild, the feral pigs are blessing and curse of Kauai. On one hand, they are sources of food. On the other hand, the pigs create big disturbances for farmers and their crops.

16. Over 90% of the land is used for agriculture

As we mentioned earlier, Kauai is known for its simple, almost countryside lifestyle. As a result, no big cities, extravagant resorts, or theme parks occupy the territory of the island. Instead, practically all the land is devoted to agriculture and conservation.

17. Kauai coffee is the largest coffee grower in the USA

Taste Paradise. One cup at a time.

Yes, please! Even if you are, like myself, not a big coffee drinker, can you say “no” to a cup of freshly roasted organic Kauai coffee before beginning your personalized walking tour among coffee trees of the largest plantation in the country? I do not think it is humanly possible!


18. Kauai is Hollywood’s favorite movie-shooting location

Kauai is undeniable. Even the mighty Hollywood agrees with me on that. And as a proof of its love to Kauai, the biggest filmmaker presents to the world such classics as Jurassic Park, Pirates of the Caribbean, Indiana Jones, 6 Days 7 Nights, The Descendants, and many more movies, all filmed on this paradise-like island.

19. There is no daylight savings time on Kauai

…And neither in the whole state of Hawaii. No daylight savings time – and therefore no hassle and unexpected effects on the human body.

20. Hawaiian alphabet has only 13 letters

With 13 letters, compared to 26 letters in the English alphabet, native Hawaiians had hard time naming places and things. In order to communicate and keep themselves safe from outside dangers, they had to get creative with those few letters. Often, they gave the same or a very similar name to two completely different things. The only way the natives later recognized the meaning of the word was by using it in context.

Final Words about Kauai

Each of these 20 things to know about Kauai offers you insides and little secrets and helps make your upcoming island vacation a trip that will stay with you for years to come. So with a little preparation beforehand, Kauai will far surpass your wildest dreams and highest expectations.
