Select participants and date
The oar cuts the river and the Balsa answers—sometimes a playful nudge, sometimes a sudden shove. You push off from a green, loamy bank with the rainforests of northern Costa Rica rising like a wall on either side. Mist from recent rains hangs in pockets above the water; birds call from hidden perches as your small group learns the rhythm of the raft and the commands of a guide who grew up with these currents.

Adventure Tips
Wear secure water shoes
Closed-toe, grippy water shoes prevent foot injuries on rocky riverbanks and keep toes from getting pinched during wet exits.
Bring a waterproof bag or case
Protect phones and spare clothes; guides store essentials but a small dry bag is invaluable when splashes are constant.
Hydrate and eat before the trip
A hearty, light breakfast and steady hydration stave off fatigue during the six-hour outing and after heavy paddle stretches.
Follow guide commands immediately
Quick, unified responses to calls like 'forward' or 'brace' keep the raft stable and reduce risk during technical rapids.
