What to Expect on the Secret Falls Kayak + Hike in Kauai

The most common way to visit Secret Falls in Kauai is on a guided kayak + hike tour. And at the end of the hike, if conditions permit, you can even cool off with a swim under the waterfall if you choose!

Your excursion begins with a paddle up the scenic Wailua River, the largest navigable river in Kauai (and, indeed, in all of Hawaii). The river is fringed with lush rainforest on both banks, and you may see water birds as you paddle.

Since the kayak tour is guided, you’ll be accompanied by an experienced guide and receive a paddling lesson at the start, helpful if you are a kayaking novice, along with information on water safety.

The paddle is about 2 miles each way, and should take you about 45 minutes each way.

Once you secure your kayak at the end of the paddle, you will follow your guide on an exciting hike through the rainforest. The vegetation is incredibly lush, with every shade of green you can imagine, and every size of leaf.

The hike is about one mile each way, with an elevation gain of about 500 feet. It’s a low moderate hike when conditions are dry.

But if it has rained recently (a more than likely occurrence in east Kauai, especially in the winter months), the trail becomes super muddy and slick in places, making it more of a moderately challenging route.

There is a river crossing involved, and one of the advantages of a guided excursion is that your guide will know when it’s safe to cross.

When conditions are right (as assessed by your guide), you can cool off from your paddle and hike with a nice swim in the cool waters beneath the waterfall.

For active visitors to Kauai, the Secret Falls kayaking and hiking tour is undoubtedly a highlight. We have done it twice now and enjoyed it both times!

This tour was a highlight of our visit to Kauai. Our guide was incredibly knowledgeable about the island plants, animals, and birds. Plus, he was very funny and relatable for kids. The kayaking was gorgeous–2 miles each way was not strenuous. The hiking was also quite flat but very muddy so wear good shoes that can get wet. Everything about the tour was fun–good conversation, beautiful views, and one of the most stunningly beautiful waterfalls I’ve ever seen. Assume about 5 hours for the trip. We will return!

Secret Falls Trail in Kauai Hawaii

What to Bring on Your Secret Falls Kayak + Hike Tour

Proper footwear

The trail to Secret Falls features uneven terrain. It can also be very muddy and slick after rains, and there is a river crossing involved. Please do not show up in crocs or flip-flops!

Sandals that dry quick, have good tread, and strap securely to your feet are a great choice, as are sneakers you don’t mind getting wet. Water shoes may not offer enough of a grip, especially for the river crossing.

We swear by our Teva sandals (women’s/men’s on Amazon). We also use Keen sandals, another great option for this tour (women’s/men’s on Amazon).

Bathing suit and towel

One of the best aspects of the Secret Falls excursion is the ability to swim in the waterfall plunge pool.

If you want the opportunity to swim under the falls, be sure to wear your swimsuit under your clothes, and bring a light absorbent towel to dry off after your swim. Check out this super absorbent yet light towel on Amazon!

Sun protection

The Secret Falls kayak and hike is an outdoor activity in exposed conditions. Sun protection is a must.

Wear a sun hat with a broad brim (men’s/women’s on Amazon). Lather on the sunscreen (and use a reef safe brand!). Wear sunshades and a lip balm with SPF.

Bug repellent

You are going to be hiking through dense rainforest. Bring bug spray or bug wipes to minimize the chance of bites!

Change of clothing

At the end of the excursion, you’ll be grateful for a change of clothes before you get into your car. It’s very likely your clothes will be wet and mud-stained after your Secret Falls hike.

Snacks and drinking water

Unless you choose a tour that includes drinking water and snacks, be sure to bring you own, to stay fueled and hydrated.

Tips for Your Secret Falls Kauai Visit

Assess if this activity is right for you before you go

The Secret Falls hike is easier if you have some paddling experience, although novice paddlers receive instruction at the start of the tour and most beginners get the hang of it very quickly. Plus, the river is quite placid, making it easier to paddle.

If you are traveling with younger kids (age 6-9), you’ll want to assess if they will be able to hike a couple of miles on uneven terrain in potentially muddy and slick conditions.

Older visitors will likewise want to make sure they are physically fit enough to hike in these conditions, where the potential for a fall in the mud exists. There’s also a stream crossing to maneuver.

Choose a morning tour for lower crowds on the hike…

The Secret Falls kayak and hike excursion is one of the most popular things to do in Kauai.

Unless you choose an early morning start time, expect the trail and the plunge pool at the falls to be very crowded on most days. If you start early, you will likely have a much more secluded experience at least on the way to the falls.

…And calmer conditions on the river

The wind tends to kick up in the afternoons.

While paddling up the river to the falls is easy because you will be traveling with the breeze, the return paddle will be a little more challenging.

Earlier in the day, conditions usually tend to be calm, making the paddle easier in both directions.

Use ziploc bags to protect phones and cameras

Your tour operator will likely offer a water-resistant day bag to store your belongings while you paddle and hike, but even so, unless your phone and camera (and any other expensive device) is waterproof, encase them in protective covering to keep them dry.

Choose a dry spell for this activity if your itinerary allows

When it rains (and it rains often on Kauai!), the trail to Secret Falls gets muddy and slippery. Plus, the waterfall can become a torrent and the plunge pool muddy.

If your itinerary allows, plan this excursion for a day when it has not rained recently.

Waterfall Safety

Waterfalls can be exciting, but safety is paramount. Always carefully assess conditions on the day of your visit.

  • Heed all warning signs.
  • Remember that flash flooding can occur with very little or no warning, even if it isn’t raining or stormy where you are.
  • Waterfalls, streams, and other water bodies may not be safe for swimming. The water may not be safe to drink.
  • Rocks, logs, and other debris may tumble over waterfalls into plunge pools or streams below.
  • Always stay on designated trails. Expect muddy and slippery conditions.

Also make sure kayak rentals are available on the date you plan to visit. Call ahead and reserve your rental to be sure you’ll have a kayak on the day of your trip.

Also know that flash floods can make the river crossing on the hike dangerous at times. Do not venture into the water if the level is too high.
