Grizzly River Run, River rafting ride at Disney California Adventure, United States.

Grizzly River Run is a river rafting ride at Disney California Adventure Park where circular boats navigate through rocky terrain and caves around a mountain peak. The route features multiple water drops and various natural water effects that shape the experience throughout the ride.

The attraction opened in February 2001 as part of the new California Adventure Park and was developed in response to the success of similar water rides at other Disney parks. It marked an expansion of the park's ride offerings during that period.

The ride incorporates California's national parks into its design, with ranger stations and natural outdoor settings visible throughout that reflect how the state's wilderness is celebrated. Visitors walk through environments that feel like actual park landscapes, making the outdoor heritage tangible during the experience.

Riders must be at least 42 inches (107 cm) tall to board, and lockers near the entrance store electronics and items that should stay dry. It helps to use waterproof bags for valuables and wear non-slip footwear before the ride.

The specially engineered rafts spin while descending a 22-foot (6.7 m) drop, creating an unpredictable water experience different from traditional rafting rides. This rotating motion amplifies the thrill and fundamentally sets the ride apart from other similar attractions.
