More ways to explore the area's outdoor wonders
You step off the shuttle and feel the rainforest breathe — humid, green, and alive — as guides unload bright rafts beside the Rio Balsa. A thirty-minute drive from Arenal/La Fortuna opens into a ribbon of water that threads through old volcanic sediments and lowland tropical forest. The briefing is brisk: safety commands, paddle positions, and a quick practice run on dry land before you slide into the current.
