La Fortuna White Water Rafting: Rivers Under Arenal

Two main rivers are within reach of La Fortuna and the Arenal hotels. The Balsa River is the gentle, family-friendly Class 2–3 run close to town. The Sarapiquí River, an hour or so away on the northern lowlands, ranges from easy floats to a punchy Class 3–4 (and even Class IV) jungle run. Some operators also run fuller Class 3–4 day trips that start and end in La Fortuna.

Yes — the Balsa River is one of the best family rafting trips in Costa Rica, run as a forgiving Class 2–3 with a swim-and-fruit stop, helmets, life jackets and bilingual guides. First-timers and kids who meet the operator's limits do it all the time. If you want more of a challenge, the Sarapiquí steps up to Class 3–4. Always confirm exact age and weight limits when you book.

That's the appeal of rafting from La Fortuna — it's close. The Balsa is a short drive from town, usually well under an hour, and most trips include hotel pickup. The Sarapiquí is a bit farther out on the northern lowlands, around an hour or so each way. Either way you're typically back in town with time left for hot springs or a volcano view.

Most do. Trips generally include round-trip transport from La Fortuna and many Arenal-area hotels, plus lunch and (on the gentler runs) a fruit and swim stop. Pickup zones and times vary by operator and some have a distance limit from town, so check the exact terms on your booking confirmation.

Wear a swimsuit under quick-drying clothes and closed-toe shoes that won't fall off — no bare feet or loose flip-flops. Bring sunscreen, insect repellent and a dry change of clothes for afterwards. Helmets, life jackets and paddles are provided. Leave phones, wallets and anything you don't want soaked in the vehicle; many operators offer a photo package so you don't have to risk your own camera.

The gentle Balsa River family trips start from around $79–$80. The Class 3–4 day trips and the Class IV Sarapiquí runs cost more, generally from around $96–$130 depending on the operator, river section and what's included. Most trips include transport, gear and lunch. Check the live price on the booking widget for current rates and dates.

La Fortuna's rivers run year-round. The green season (roughly May to November) brings heavier rain and bigger, faster water — the most exciting rafting, especially on the Sarapiquí. The drier months (December to April) bring warmer, friendlier flows and clearer views of Arenal Volcano. Morning departures usually have the calmest weather and leave the afternoon free.

Pick the Balsa if you want a gentle, family-friendly half day of Class 2–3 whitewater close to town. Pick the Sarapiquí if you want a bigger, more demanding run — it has Class 3–4 sections and a Class IV extreme option for confident paddlers. Both leave from the Arenal area; the comparison table on this page lays them out side by side.

You don't need to be a strong swimmer for the gentle Balsa, but basic comfort in water is important on any river, and you should be a confident swimmer for the Class 3–4 and Class IV Sarapiquí runs. Everyone wears a life jacket and helmet, and guides brief you on what to do if you end up in the water. Tell your guide about any concerns before you launch.

Easily. Because the gentle Balsa is a half-day trip and the rivers are close to town, many travelers raft in the morning and visit the hot springs, La Fortuna Waterfall or the hanging bridges in the afternoon. Some operators also bundle rafting with canyoning, ziplining or a Tarzan swing into a single adventure day.

It depends on the river you want. La Fortuna is the most convenient base for the family Balsa and the Sarapiquí, with short transfers and hotel pickup. San José is the launch point for the bucket-list Pacuare River, a full-day Class 3–4 gorge run. If you're staying in Arenal, raft locally; if the Pacuare is your goal, base near San José for the day. See our Pacuare River rafting guide for that trip.
