Kayak, hike, then swim under a waterfall. This Wailua River guided combo is one of the best ways to see Kauai’s power and culture in one half-day: a paddle upriver, then a rainforest trail to the 120-foot Ulewehi Falls. I love the way the guide weaves ancient river life into the walk and paddle, and I love the included dry bag and life vest setup so you can move fast and stay comfortable. The main catch: it can get very muddy, and you may wade through water—so plan for wet shoes and slippery footing.

Small groups make the experience feel personal. When Levi (Levy) is your guide, you can expect patient coaching plus stories and music with his ukulele, and the team runs with strong safety habits taught through certified training (lifeguard, CPR, first aid). Plan a moderate fitness level, and you’ll be rewarded with views, photos, and a waterfall you can actually cool off in.

Key Highlights You Should Know Before You Go

• Only navigable river on Kauai: a 2-mile paddle upriver each way with your guide
• Kamokila Village stories along the route: you’ll pass traditional huts and hear ancient river connections
• Ulewehi Falls hike (about a mile each way): mostly boardwalk, plus muddy sections and stream crossings
• Swim break at the waterfall pool: cold, swimmable water when conditions allow
• Gear is fully handled: kayak, PFD, waterproof dry bags, and small coolers for snacks
• Max group size of 12: easier pacing for a hike with slippery sections

First: Mud, Water, and the Real Difficulty Level

This is a half-day adventure, but it’s not a sit-and-watch kind of tour. You’ll kayak about 2 miles up and 2 miles back, then hike to Ulewehi Falls and return. The weather changes everything, especially trail conditions.

If recent rain has hit, expect slushy mud, slick boardwalk spots, and frequent water contact. Even in drier periods, you still need traction because trails can mix planks, dirt, and rock scrambling.

That difficulty is also why this trip feels like a real Kauai outdoor day instead of a quick photo stop.

Wailua River Kayak: A 2-Mile Paddle Each Way You Can Actually Enjoy

Your day starts with a check-in at a kiosk at Coconut Marketplace near the iconic water tower. After you meet your guide and get outfitted, you’ll head to the river launch point on the Wailua.

You’ll use double sit-on-top Ocean Kayaks, plus a paddle and life vest. Your belongings go into a water-resistant dry bag, which matters more than you might think, because you’ll be in and out of water and dealing with wet ground during the hike.

Then comes the fun part: a gentle-current paddle about 2 miles upriver toward the north fork. From the water, you get dramatic volcanic peaks in the distance and the tight, green feel of Kauai’s river corridor.

The paddle is long enough to feel like exercise, but most people find the pace manageable with a guide steering you to good routes. If winds are up, you’ll feel it more on the return, so keep your energy for the bounce-back at the end.

Kamokila Village: Why the Paddle Isn’t Just Pretty Views

One reason people love this tour is that it’s not only about motion. As you move upriver, you pass by Kamokila Village, with traditional huts you can spot from the water.

Your guide shares stories about the people who lived and traveled these waterways long ago, with references to river use stretching more than 1,500 years. That context changes how you look at the river turns and the quiet stretches.

It also helps you understand why the Wailua River is treated as more than scenery. It’s a living route with spiritual and cultural importance for Hawaiians, and your guide keeps the tone respectful.

So when you stop paddling to listen, you’re not just waiting. You’re taking in the landscape the way locals and historians would frame it.

Secret Falls Trail to Ulewehi Falls: Boardwalk, Scrambles, and Worth-It Payoff

After the paddle, you get out of the kayak and start the hike. The trail leads through Wailua State Park toward Ulewehi Falls, with a moderate route that mixes boardwalk and natural trail.

Expect a mix of footing: some sections are basically a walkway, while others turn into damp, uneven ground. You’ll also deal with stream crossings, and the conditions can range from firm to messy depending on the rain.

The waterfall itself drops about 120 feet (36 meters) off a cliff. The hike is long enough to build anticipation, but it’s short enough that most active adults can do it if they take their time.

Your pace matters here. The goal isn’t speed. It’s staying balanced and reaching the falls without slipping out of rhythm.

Waterfall Pool Break: Swimming, Photos, and the Cold Reality Check

Once you reach the falls area, the atmosphere shifts from active hiking to “pause and take it in.” This is the moment you’ll remember when you look back at your photos later.

There’s often a chance to swim in the cool pool at the base. In past outings, people have gone in even when the water felt very chilly, so don’t assume warm water just because it’s sunny outside.

You’ll also want to keep an eye on where you step. The route down to the waterfall and around the pool can get slippery, and you’ll be juggling wet feet, rocks, and camera angles.

If you’re going to swim, wear practical gear: water shoes or sandals with grip, and quick-dry clothes you don’t mind getting soaked.

What’s Included (and What You’ll Still Need to Bring)

The tour does a lot right on the “getting you ready” side. You’ll get:

• Kayak, paddle, and PFD (life vest)
• Water-resistant dry bags for your items
• Small coolers with snacks
• Snacks like granola bars, chips, cookies, and trail mix, plus water
• Parking fees for the state park included

You’re also told to bring your own bottle if you want, and you can fill up at a water fountain. That’s handy in Hawaii, where hydration is not optional.

What you should bring:

• Water shoes or closed-toe shoes with grip (Tevas/Keens-type sandals can work, but anything stable is best)
• A change of dry clothes for after
• A light layer for the ride back if you get cold easily
• A swimsuit if you want to swim, and some people find it easier to wear it under their clothes

And here’s the part that surprises people: the state park entry fee is not included in the tour price. It’s $5 per person, paid at the Marina, with credit or debit cards only. The tour company won’t collect that fee for you.

Meeting Point and Timing: How This Day Flows Without Confusion

You’ll meet at 4-484 Kuhio Hwy, Kapaʻa, HI 96746, and the tour ends back at the same meeting point. There’s no hotel pickup or drop-off, so plan on getting there under your own steam.

Check in starts at Coconut Marketplace (right under the iconic water tower). From there, the day moves through kayak outfitting and the river route, then transitions to the hike.

This is typically about 6 hours total, and it’s scheduled to start early so you get better morning conditions. If you’re doing a Kauai itinerary with limited time, this timing can work well because you’ll still have part of the day left afterward.

Also, the max group size is 12, which usually means less waiting and a more controlled pace on the hike.

Price and Value: Is $145.03 Worth It?

At $145.03 per person, this isn’t a budget activity. But you’re paying for a lot that would be hard to DIY well: local guidance on the best routes, safety oversight, and the full water-and-trail gear setup.

The included kayaks, life vests, dry bags, and guided hike reduce the hassle factor. The guide also adds the educational layer, with stories that connect what you’re seeing to ancient Hawaiian river use.

The only extra cost you should plan for is the $5 state park entry fee. If you budget that in ahead of time, the final spend feels more predictable.

One more value point: smaller groups and certified safety help you take this on without needing to be an expert paddler. You’re still active, but you’re not wandering around alone.

Who This Tour Fits Best (and Who Might Want a Different Plan)

This is best for people who want a day that mixes water time and a hike, and who won’t mind getting muddy. You should have moderate physical fitness, and you should expect uneven footing at times.

It’s also a strong pick for first-time kayakers who want coaching. You’ll get help finding good routes as you paddle, and the guide keeps you oriented.

This tour is also family-friendly with a limit: kids must be with an adult, and the minimum age is 5. If you’re traveling with children, it’s smart to watch the footing carefully and go slow.

If you have knee or ankle issues, or you know you hate cold water and slipping ground, you might find this stressful. The reviews and tour guidance both point toward mud and water contact as a core part of the experience, not a rare accident.

My Take: Should You Book This Secret Falls Kayak and Hike?

If you want a Kauai day that feels hands-on—river paddle, rainforest hike, and the option to cool off at a real waterfall—this is a great match. The star of the show is the guided combination: the Wailua River paddle plus the Ulewehi Falls hike gives you two different kinds of nature in one outing, and the small group size helps keep it smooth.

Book it if you’re comfortable with wet shoes, slippery sections, and a moderate hike. Skip it if you want a dry, easy stroll or if mud would ruin your day.

Finally, pick your timing with weather in mind. When rain is recent, trails can be messy, but water conditions often mean more waterfall presence. Either way, bring traction and a good attitude, and you’ll likely leave with photos and stories that feel very Kauai.
