The Cedar Ridge Observatory is an observatory in Cedar Grove, Shoreside Vale, Liberty City, in Grand Theft Auto III and Grand Theft Auto: Liberty City Stories. The observatory is normally inaccessible to the player. However, if the player manages to reach there, the ground is not solid so the player cannot land on or near it. The observatory is featured on Rockstar's site for GTA III.
