Big Grizzly Mountain Runaway Mine Cars is the headline attraction of the Grizzly Gulch area. It is similar in style to the Big Thunder Mountain Railroad mine train coasters at other Disney parks, but also brings in elements from the Expedition Everest coaster at Disney's Animal Kingdom.

The first third of the ride is spent plummeting backwards down a twisting, turning hill, before being blasted forwards by an "explosion". The circuit then takes in most of the Grizzly Gulch area, including the Geyser Gulch water play area.
