Select participants and date
The morning starts before the city wakes: a van slips away from San Francisco under a pale sky, and the urban grit loosens into rolling foothills. By the time the guide straps the last wetsuit in the back, the American River has already claimed the valley’s attention—its current a lively voice, daring you to match its pace.

Adventure Tips
Hydrate before and during the trip
Bring a refillable bottle; guides provide bottled water but you’ll want fluids before getting wet to prevent cramps and fatigue.
Wear secure, closed-toe water shoes
Grip matters—rafts and riverbanks are slick; sturdy water shoes or old trail runners prevent slips and blisters.
Follow the safety briefing exactly
Paddle commands and re-entry practice are mandatory—pay attention to stay safe in Class III conditions.
Protect electronics with a dry case
Phones and cameras should be in sealed dry bags or left on shore to avoid irreparable water damage.
