Hiking in Kaua’i
The island of Kaua’i is beautiful and is well known for it’s abundance of hiking trails. Explore the many areas and get tips for hiking the trails of Kaua’i here and hike Kaua’i!
What to bring for hiking in Kaua’i
When you go to Kaua’i, or any Hawaiian island, your top items should (obviously) be a couple of bathing suits, flip flops, sunscreen and a hat! For hiking, you’ll need a few more things, and while some are fairly obvious, there may be some things you didn’t think of. The island is fairly rainy and there are lots of jungle hikes you can do, so you’ll need to bring some protective outerwear.
Ideally you should bring a pair of hiking shoes or trail running shoes that are made with Gore-tex. There are some deep puddles in a lot of the trails, and you’ll be thankful when your feet are dry.
- Hiking shoes, preferably with gore-tex
- A backup pair of sneakers you don’t mind getting dirty with jungle mud, it’s very very muddy on some of these trails. Try to get ones made with gore-tex or other water resistant fabric to keep your feet dry.
- Long, thin and breathable hiking pants to protect your legs during jungle hikes
- Long sleeve and short sleeve hiking shirt
- A thin windbreaker shell jacket for rain and to protect your arms when hiking. For example, try the Cotopaxi Teca full zip windbreaker
- Wool hiking socks. Wool dries quicker and keeps the temperature in your shoes regulated
- Hiking poles – very helpful for puddle hopping on some of the many muddy trails on the island
- Small backpack. Since you don’t need an excessive amount of gear for day hikes because it’s so warm, a 20L pack full mostly of water and food will do. Choose a pack with a moisture wicking back to keep your back as dry as possible. Try the Osprey Stratos daypack, it has a breathable mesh back and water reservoir bladder
- Lots of water. The heat is quite dehydrating, and even though it’s humid, it’s hard to drink enough sometimes. It’s a good idea to take a hydration bladder. If you do run out of water, make sure you have a water filter or water treatment drops.
Water drinking considerations
Though in some alpine areas it is occasionally safe to drink untreated water, it’s very unsafe to do so in Kaua’i. The tropical climate means all sorts of bacteria and microorganism thrive; including flesh-eating disease! You don’t want to go into some streams or rivers if you have any open wounds, never mind drink untreated water from them. Make sure to always treat your water.
Recommended guide book
There are a number of good guidebooks for the island, but my favourite is The Ultimate Kaua’i Guidebook, written by long time Kaua’i resident Andrew Doughty. It has a great personal touch written by someone who actually lives on the island full time and is an avid hiker. We like this book because Andrew actually loves hiking and has hiked most of the trails on the island, so his trail descriptions are really good, honest, and very accurate.
Can I get to the highest point on Kaua’i?
In case you’ve been wondering: yes, you can access the highest point in Kaua’i, but it’s not easy.
Hawaiian islands are all quite mountainous. They were created recently volcanic activity, and many visitors wonder how to get to the top of the highest peak or crater on each of the islands. On Big Island there is Mauna Kea and on Maui there is Haleakala. So naturally, many will wonder, how to get to the highest point in Kaua’i. In Kaua’i, the ancient volcano is a large crater, known as Waiale’ale. This crater is also known as the Blue Hole, and is completely lush, green, and usually in thick cloud.
The wettest spot on earth
The highest point on Kaua’i is the old Waiale’ale crater, at 5148 feet (1569 m) is also the wettest spot on earth. It seems like a fascinating, beautiful place, but it’s definitely not the world’s most glamorous hike. Until a few years ago, it wasn’t even possible to get to the top because it was too hard to navigate, but now a conservation fence makes a nice landmark. You’ll have to find the fence in order to orient yourself, and after that you should be able to get on the trail and to the top without too much issue. Be prepared however, for thick, misty jungle and loads of mud. The trailhead is 4 miles in a forestry road, and you’ll need a 4 WD vehicle to access it. Find a some good information about the hike here.
You won’t be able to find the trail without a map (the smartphone app that comes with the Kaua’i Revealed guidebook is recommended). It’s a slog, it’s wet, muddy, slippery and is a 20 mile long round trip, meaning it would take two days to complete. The jungle is thick, and it’s mostly in the rain and clouds so it’s unlikely you’ll get any views either. Nonetheless, it sounds like a great adventure, and a few people commit to doing it. It takes two hours to get from one end of the summit plateau to the other.
The summit of Wai’ale’ale is so rainy that on the plateau, aside from some scraggly trees, nothing is over a foot tall, and it’s blanketed by fern and moss. Few plants are equipped to deal with this much rain and cloud cover.
It is called the wettest spot on earth for good reason, it averages more than 452 inches of rain a year (11,500 mm)! The Wai’aleale crater is one of the many hiking trails on Kaua’i, and definitely the least popular.
