The boat slips away from the bank and the Peñas Blancas whispers ahead, clear water threading between dark river stones and low, green fingers of rainforest. For two hours the river sets the pace: slow reaches reveal sleeping crocodiles on sunlit sandbars, tight bends flock with kingfishers, and high trees rustle with howler and capuchin monkeys that watch the passage.

The boat slips away from the bank and the Peñas Blancas whispers ahead, clear water threading between dark river stones and low, green fingers of rainforest. For two hours the river sets the pace: slow reaches reveal sleeping crocodiles on sunlit sandbars, tight bends flock with kingfishers, and high trees rustle with howler and capuchin monkeys that watch the passage.
This stretch of river runs through volcanic soils laid down by the nearby Arenal system; erosion and sediment have carved shallow channels and oxbows that host a rich mosaic of habitats. The area supports traditional cattle and smallholder farms, and recent conservation efforts—often tied to eco-tourism—focus on reforestation and protecting riparian corridors.
Practically speaking, expect an 8-kilometer guided float in a covered small boat departing from La Fortuna, with private transport and life jackets included. The operator pauses for wildlife viewing, a guided tree-planting activity to offset local deforestation, and finishes with a traditional snack. The outing is rated easy and suitable for most fitness levels, but weather and river levels affect visibility and wildlife activity.
Tip: schedule morning departures for calmer water and higher bird activity; late afternoon light can make crocodiles easier to spot. Bring sun protection, insect repellent, a waterproof layer for spray, and binoculars. Follow guides’ instructions around wildlife—do not feed animals or leave trash. The river rewards quiet attention: it will reveal its inhabitants slowly, but memorably.
The guided river segment covers about 8 kilometers and lasts roughly 2 hours, within a full 4-hour outing including transport from La Fortuna.
Yes—crocodiles and several monkey species are commonly sighted, but sightings depend on time of day and river conditions and cannot be guaranteed.
The activity is rated easy and accepts infants (on laps), but boarding a small boat requires basic mobility; contact the operator about specific accessibility needs.
Standard cancellation allows a full refund if you cancel at least 24 hours before departure; the operator may cancel tours in bad weather.
