The White Chuck boat launch is located just downstream from the confluence of the White Chuck and Sauk Rivers. This site offers non-motorized boat access to the Middle Sauk River for rafting and kayaking on the Darrington District. This stretch of river known for its whitewater thrills is a favorite in the Skagit System. Rapids are class II-III, but rise to class IV during high flows. The typical rafting is from late May to early August. A short trail follows the river downstream to several viewpoints with interpretive signing. The launch is walk in only with no ramp and will put you in at river mile 31.8. Rafting guides
