Six Rivers Rafting Inc., based in Junction City, California, guides river adventures on the Trinity River. The company offers a diverse lineup of guided trips, from half-day Class III whitewater kayaking and rafting trips to full-day scenic Class II excursions and challenging upper-river runs featuring continuous Class II–III and Class III–IV rapids. Trips include family-friendly options, pet-friendly departures on select runs, and experiences that combine floating, wildlife viewing, cliff jumping, and swimming holes.
Full-day and half-day itineraries feature organic lunches or light snacks depending on the trip, and some full-day trips include professional photography. The Full Day Lower Trinity and Upper Trinity scenic trips begin from Willow Creek and other river access points, offering secluded canyons, sandy beaches, and opportunities for hiking to waterfalls. The operation also runs multi-day training programs: a five-day River Guide School with expert instructors, free camping, and provided gear to train aspiring professional guides, plus a five-day Teen/Youth Guide Camp and River Safety Training for campers aged 11–17 that focuses on rafting skills, teamwork, and river safety.
Safety, instruction, and guest experience are central to the offerings: guides teach river skills, steering, and rapid navigation on appropriate class sections. Trips accommodate beginners and experienced paddlers alike, with clear distinctions between serene scenic floats and adrenaline-driven whitewater runs. Six Rivers Rafting Inc. provides locally based, professionally managed river adventures on the Trinity River for families, adventurers, and future guides. Reservations and trip details are provided through the company's booking channels. Seasonal schedules and availability vary seasonally.
