Seven river and paddling options are listed on Kauai, from $60 to $236. Three are guided kayak trips to a waterfall at $119, $145 and $157 — and 294 of their 315 combined reviews sit on the $119 five-hour trip. Two are self-guided rentals at $60 and $69, neither reviewed yet. Two are long day tours at $231 and $236 that pass the river as one stop. The constraint that decides your week comes first: commercial kayak tours and rentals on the Wailua do not run at weekends. The state canceled Saturday permits on 4 December 2021 and Sunday was already closed.
01 — Why there is a choice at all
Prices read from the operator catalog on 26 August 2026 · lowest listed price per person
That is the state tourism authority's wording, and it is worth repeating exactly, because most pages shorten it into something false. Not the only river in Hawaii, and not the only navigable river — Kauai holds the state's only navigable rivers, and the Wailua is the biggest of them. This is why paddling is a Kauai activity in the first place, and why the same seven listings keep appearing when you search for it.
The choice inside those seven is narrower than it looks. Three guided trips run the same route — paddle upriver, then hike to a waterfall — and differ mainly in price and in how many people have reviewed them. Two are rentals with no guide. Two are long land tours that touch the river for part of a day.
So this page sorts the seven by what you actually get on the water, states what the catalog does not sell at all, and puts a $5 alternative in the last row of the same table. If the weekend closure or the weather rules the river out, an air tour flies the whole island from $155 and the Nā Pali boats run from $215 on the ocean side.
02 — Three groups, one click each
Three guided trips that hold 315 reviews between them. Two rentals at $60 and $69 with nobody's verdict on them yet. Two long day tours at $231 and $236 where the river is one stop among several.
03 — Group one
Three guided trips run the same shape of day: paddle up the Wailua, land, walk in to a waterfall, come back. They cost $119, $145 and $157. Between them they carry 315 reviews, and 294 of those sit on the $119 five-hour trip, rated 4.8. The other two are six-hour versions with 14 and 7 reviews.
A five-star average on seven reviews is not a stronger result than 4.8 on 294 — it is a smaller sample. If the extra hour or the included lunch is what you want, the $157 trip is the one that offers it, and $38 is what that costs over the anchor price.
The day is long for what it is: five hours for a paddle plus a hike on wet ground, and the river is open on weekdays only. If five hours is too much of your week, nothing shorter is sold on the river — the roadside waterfall lookout takes as long as you want for $5 per person.
The other two, same river, far less evidence
Both run six hours instead of five, and between them they hold 21 reviews against 294 on the five-hour trip. That is why they are rows and not recommendations.
Anything under 30 reviews is marked as a small sample. Same route as the $119 trip.

04 — Group two
Two self-guided listings exist: a kayak rental with a map and a dry bag at $60, and a SUP and kayak rental at $69. Both are six-hour windows on the same weekday-only river. Neither has been reviewed yet, so both print as new listings without stars — there is no verdict to quote, in either direction.
The gap to a guided day is smaller than the headline. Non-residents pay $5 per person plus $10 per vehicle at the river state park, so a solo paddler starts at $75 rather than $60, against $119 with a guide. What the $44 difference buys is somebody who knows where the waterfall trail leaves the water — on a rental you find it yourself, or you turn back.
Two people change the arithmetic again: $60 plus $69 is not how it works, but $10 of car fee is shared while $5 per person is not. If the sum stops making sense, the guided trip at $119 removes the navigation problem entirely, and a $5 roadside lookout removes the paddle.

05 — Group three
Two long tours include the river as one stop. A six-hour northeast route from Princeville pairs a Fern Grotto river cruise with a lighthouse at $236, rated 4.5 from 93 reviews. A 9.5-hour circuit takes in Waimea Canyon and the Wailua River at $231, rated 4.7 from 72 reviews.
There is no standalone river boat to the grotto in this catalog. If the grotto is the reason you are here, these two are the whole answer, and the cheaper of them is the one that costs more of your day.
Read them honestly: these are not river tours. Six and 9.5 hours buy an island circuit in which the water is a slice. If you came for the paddle, the $119 guided trip is half the length and half the price — and it puts you in the boat rather than beside it.

06 — Three honest corrections
Two things people search for do not exist in this catalog at any price. Saying so is faster than letting you find out at the booking screen.
Not bookable here
People search for it constantly and the catalog holds no tubing product on Kauai at all — not at $60, not at $200. The nearest thing by feel is a day on the water, and that starts at $119 with a guide.
See the $119 river day →Only inside a day tour
There is no standalone river cruise to the grotto listed. It appears only as a stop inside the $236 northeast tour and, as river time, in the $231 canyon-and-river day.
See both day tours →07 — All seven, plus the no-paddle one
Seven listings from $60 to $236, ordered by review count rather than price, with a column the catalog does not print — whether you are actually on the Wailua. The last row is not a tour: it is the $5 waterfall you can see from the road, on any day of the week.
Showing 7 options plus the no-paddle row
Park fees at Wailua River State Park apply to non-residents at $5 per person and $10 per vehicle, on the paddling rows as well as the lookout row.
08 — Before you book
The first one costs people their booking more often than weather does. Check it against your dates before anything else.
This is a state decision rather than an operator policy, so confirm it at the booking screen for your dates. Weekend alternatives — an air tour from $155, a Nā Pali boat from $215, or the $5 roadside lookout. Nothing with a paddle in it runs at the weekend.
Park fees
Non-residents pay both at Wailua River State Park. A guided booking is one payment; a $60 rental is really $75 once you have parked and walked in alone.
The waterfall is a hike
Secret Falls is reached on foot after you land the kayak, on wet ground. A rental hands you no guide for that part — the $119 trip includes both halves in its five hours.
Time it costs
The $119 trip is five hours and the two dearer ones are six, which is most of a day either way. There is no short version on the water: the catalog sells nothing under five hours on the Wailua.
The wet side
The Wailua sits on the wet east side of the island, so a gray morning is not unusual and the trail turns muddy. If the forecast closes in, the dry west side and the season pattern are the thing to plan around.
Sample size
Both rentals print as new, without stars, and the $157 trip carries seven reviews. The only listing with a real record is the $119 one at 294 — that is the number to weigh against a lower price.
Departure points
Guided trips and rentals start at Wailua, and the $236 day tour starts at Princeville. Check the meeting point against where you are sleeping before you pay.
09 — Questions with numbers in the answers
No. Commercial kayak tours and rentals run Monday to Friday — the state canceled Saturday permits on 4 December 2021 and Sunday was already closed. If your only free day is a Saturday, the $155 air tour and the $215 Nā Pali boats still run, and the $5 roadside waterfall lookout is open.
Guided trips are $119 for five hours, or $145 and $157 for six. Renting is $60 or $69, plus $5 per person and $10 per vehicle in park fees for non-residents, so about $75 for one person going alone.
One hour and the size of the record. Both paddle the same river to the same waterfall; the $119 trip is five hours with 294 reviews at 4.8, the $145 trip is six hours with 14. Pay the extra only if the longer day is what you want.
Only if you are happy to navigate. A rental is $60 or $69 for six hours and about $75 once park fees are paid, against $119 guided — and the $44 gap buys somebody who knows where the waterfall trail leaves the water.
It is the waterfall at the end of the guided river day — you paddle upriver, land, and walk in. All three guided trips, at $119, $145 and $157, are built around that pair of movements; no listing reaches it without both.
Inside a longer day tour, and only there. The catalog lists no standalone river boat to the grotto — it appears in the $236 six-hour northeast tour, rated 4.5 from 93 reviews, and river time features in the $231 nine-and-a-half-hour canyon day.
Not in this catalog — there is no tubing product listed at any price. The closest thing in spirit is a day on the water, which starts at $119 with a guide or $60 as a rental.
The Wailua is on the wet east side, so rain is common and the waterfall trail turns muddy. Cancellations are handled by the operator through your booking confirmation, not through this site — and a $155 flight or the $5 lookout are the dry-day substitutes.
Yes — Wailua Falls has a lookout directly off Maʻalo Road with no hike involved. It is not free: the same state park charges non-residents $5 per person and $10 per vehicle. It is the one option on this page that works on a Saturday.
The river is one of several ways to spend a day on the water or above it.
