For more than 25 years, the customers of Sunshine Rafting Adventures have navigated the Stanislaus River's collection of rushing haystack rapids and shady straight-aways. The team specializes in low-risk, family-oriented rafting trips, and they organize packages that equip guests with necessary paddles and life jackets. To begin each 7.5-mile float, the team launches rafts near the historic Knights Ferry covered bridge—the longest covered bridge west of the Mississippi River. Guests then paddle along various features, including the Class II Russian rapids, the sharp turns of the Throw Rapids, and the lava cliffs of the Two Bluffs, where cliff swallows build hundreds of mud nests each summer.
