Arenal Rafting and Tubing from La Fortuna
Twelve trips from 26 EUR across four rivers, and the only thing in La Fortuna that improves when it rains.
Everything else in La Fortuna is quietly hoping for a dry day. Rafting is not. The rivers running off the Arenal massif are rain-fed, and more rain means more water, faster water and bigger waves, which is why the season most visitors try to avoid is the season the raft guides prefer. It is the one genuine counter-trend in this destination and nobody selling dry-season packages will bring it up.
Below: which river a listing means, what the class numbers commit you to, why the gentlest trip on the page is the best-rated thing families book here, and the one listing whose price looks too good because it does not include getting there.

Ratings collected by Viator and Tripadvisor
Four rivers, and they are not the same trip
The name of the river tells you more than the name of the tour. Twelve listings, four bodies of water, and a difference between them that runs from a gentle drift looking for sloths to genuine class IV. Operators are usually clear about the grade and less clear about the drive, which is the other thing that changes your day.
| River | Grade | Price | Getting there | Book it if |
|---|---|---|---|---|
| Río Balsa | Class II to III | 82 to 148 EUR | About 20 minutes | You want whitewater without a long drive |
| Río Sarapiquí | Class II-III or III-IV | 93 to 100 EUR | About 1 hour each way | You want the bigger water |
| Peñas Blancas | Class I, a float | 62 to 78 EUR | Short | You want wildlife, not rapids |
| La Fortuna river, tubing | Class I to II | 57 EUR | Minutes | You want the cheapest thing on water |
| Lake Arenal, kayak or board | Flat | 26 EUR | You arrange it | You have your own transport |
Rain makes this better, which is the opposite of everything else here
These are rain-fed rivers on the wet slope of the continental divide. In the dry months the Balsa runs lower and the class III sections behave more like class II, which is fine for a family and disappointing if you came for the waves. From about September to November, when the rest of La Fortuna is complaining about the afternoons, the rivers are full and the trips are at their best.
One operator on this site claims the Balsa has an excellent level of water throughout the year, and that is a fair description of a river that never actually dries out rather than a promise that January and October feel the same. They do not. If the rapids are the point of the trip, book the wet months. If you have children who are nervous about water, the dry season is the friendlier version of the same river.
There is a limit at the top end. After extreme rainfall operators cancel, because a river in flood is not a bigger version of a good day, it is a different and worse thing. That is a decision the guides make on the morning and it is not negotiable.
| 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | 11 | 12 |
Every other listing in La Fortuna quietly hopes for sunshine. The raft guides check the rain gauge and hope it kept going overnight.
What the class numbers actually commit you to
Class II to III is the family grade and it is what most people should book. Waves, some splashing, a couple of sections where the guide shouts and everyone paddles, and long calm stretches between them. One Sarapiquí operator here takes children from seven years old on this grade, which is a useful benchmark: if a listing does not state an age, ask, because the answer varies more than the grade does.
Class III to IV is a different proposition. Bigger drops, more continuous water, and a real chance of coming out of the boat, which is a manageable event if you are a confident swimmer in moving water and a frightening one if you are not. Operators set higher minimum ages for it and expect you to be able to swim. Nobody will test you, which is precisely why you should be honest with yourself at the booking stage rather than at the top of a rapid.
Everyone gets a helmet, a buoyancy aid and a safety briefing that includes what to do if you fall in, and the briefing is worth listening to rather than half-hearing. Feet downstream, on your back, hold the paddle. That is most of it.
The safari float is not rafting, and it is the best family day here
On the Peñas Blancas there is a trip that involves no rapids at all: a raft or a kayak drifting downstream while a naturalist points out sloths, howler monkeys, iguanas, caimans and a long list of birds. It is class I, it is calm enough for people who do not like water, and at 62 to 78 EUR it costs less than the whitewater.
It is also, by the numbers, one of the best-received things in the whole area. The float carries 510 reviews at 5.0 and the kayak version 82 at 4.9. If you have small children, a nervous partner, or you have already spent three days being strenuous, this is the river trip to book, and the fact that it is filed under rafting is the only reason people miss it.
What to wear, and what to leave in the van
Quick-dry clothes over a swimsuit, and nothing made of cotton, which stays wet and cold all afternoon. Footwear that is strapped to your foot: river shoes, trainers you do not mind soaking, or sandals with a heel strap. Flip-flops will be at the bottom of the river inside ten minutes and several operators simply will not let you board in them. A strap for glasses, and sunscreen applied before you get in, because you will not be reapplying it mid-rapid.
Leave everything else. Phones, watches and wallets go in the guide's dry barrel or stay in the vehicle, and the operator's own photographer takes the pictures from the bank, which is why photographs are sold as an extra on almost every one of these listings. Bring a dry set of clothes and a towel for afterwards, since most trips finish with lunch and nobody enjoys that soaked.
Prices, and the listing that does not include getting there
The cheapest thing on this page is a kayak or paddleboard rental on Lake Arenal at 26 EUR, and its own title says why: transport is not included. The lake is not walking distance from La Fortuna, so unless you have a car that 26 EUR becomes 26 plus a taxi each way, which changes the arithmetic completely. It is a good listing and it is not the bargain it appears to be in a price-sorted list.
Straight rafting sits at 82 EUR on the Balsa with lunch, 93 on the Sarapiquí at class II-III, and 100 for the class III-IV. Tubing is 57. Above 130 EUR every listing here is a combination: rafting with an ATV run at 133 to 147, or rafting with canyoning at 141 to 175. Those combination days are long and the two halves are both good, but you are paying for the second activity, not for a better river.
Questions people actually ask
Is rafting better in the rainy season?
Yes, and it is the only activity in La Fortuna of which that is true. These rivers are rain-fed, so the wet months bring higher water, faster flow and bigger rapids, with September to November the strongest window. In the dry season the Balsa drops and its class III sections behave more like class II. The only exception is after extreme rainfall, when operators cancel because a river in flood is genuinely dangerous.
Which river should I book?
The Balsa if you want whitewater with a twenty-minute drive and a family-friendly grade. The Sarapiquí if you want bigger water and do not mind an hour each way, and it is the one that offers class III-IV. The Peñas Blancas if you would rather look for sloths than paddle through waves. Lake Arenal if you want a kayak and have your own transport.
Can children go rafting near Arenal?
Yes, on the class II to III trips. One Sarapiquí operator on this site takes children from seven years old, which is about the youngest quoted in the area, and minimum ages differ between operators so it is worth asking rather than assuming. Class III-IV carries higher age limits and expects confident swimmers. The Peñas Blancas wildlife float has no rapids at all and suits any age.
Do I need to be able to swim?
For class II to III, not strictly, since you wear a buoyancy aid and the calm sections are long, but being comfortable in water makes it far more enjoyable. For class III to IV, yes, genuinely: coming out of the boat is a normal event on that grade and being a confident swimmer in moving water is what turns it from frightening into a story. Nobody will test you, so be honest at the booking stage.
How long does a rafting trip take?
Four to six hours door to door, of which roughly two are on the water. The rest is transfer, briefing, kitting up and, on most trips, lunch afterwards. The Sarapiquí trips are at the long end because of the hour's drive in each direction. Tubing is shorter, at about two to three hours in total.
What should I wear?
Quick-dry clothes over a swimsuit and nothing cotton. Footwear that is strapped on: river shoes, old trainers or sandals with a heel strap, never flip-flops, which several operators will refuse to let you board in. A strap for glasses and sunscreen applied before departure. Leave your phone in the vehicle or in the guide's dry barrel and bring dry clothes for afterwards.
