Description

Big Bull rapid features a technical boulder garden with multiple potential lines requiring precise maneuvering and good boat control. The rapid's center channel contains several sharp-edged rocks and a moderate diagonal hydraulic that can create unexpected lateral movement, demanding careful route selection and immediate corrective paddling. Experienced paddlers should scout the rapid's entry and identify the cleanest path to avoid potential pin or entrapment hazards in the rock-choked sections.
