The Disneyland Mountain Challenge is a new trend around the park. The challenge is riding the four mountains (Splash, Space, Matterhorn and Big Thunder) in under an hour. Your time will start on Main Street USA in front of the Partner Statue.
You are allowed to use Fast passes and single rider. Something to take into consideration is Big Thunder will usually have one train and track open during rope drop along with Matterhorn, which generally has one side open. Having one train and one tack open will slow you down, but it’s not impossible.
