Grizzly Bear Valley Mining Vehicle Project is a roller coaster in Hong Kong Disneyland. Seeing that there were not many people, I went to the queue and basically did not wait. After sitting on it, I tied my seat belt and the staff checked it again. After starting, the Grizzly Bear Valley train is still very exciting when it brakes, turns sharply and reverses. When we got down, a group of people came to line up.
