The river bends slow and wide as you step into a low-profile raft, the morning mist lifting off dark water that threads down from Arenal’s slopes. Birds call from the canopy and a sloth—motionless and patient—hangs like punctuation in the branches. The guide eases the boat forward; the current nudges you along and the forest leans close enough to read the moss on its roots.

Peñas Blancas is part of the Arenal drainage that feeds into Lake Arenal, a landscape reshaped by volcanic flows and the lake’s mid-20th-century dam. Geology here is recent and visible: basalt outcrops, river-smoothed boulders, and alluvial banks that host dense riparian forest. Culturally, the nearby town of La Fortuna grew with ecotourism, and many local guides are born-and-raised interpreters of this living landscape.
The trip focuses on accessible wildlife viewing—sloths, toucans, kingfishers, and the occasional troop of white-faced capuchins—while guides pause to point out tree species and animal signs.
Practical guide: tours run 2–4 hours with hotel pickup from La Fortuna; choose a morning slot for the most active birdlife. Wear quick-dry clothes and water shoes, bring sun protection and a dry bag for valuables. Expect gentle currents and short walks to and from rafts; the activity is suitable for most fitness levels, and infant seats are available. Respect viewing distance—don’t feed animals—and follow your guide’s directions for a safe, low-impact experience on the water.
