Castle Hill is a huge pink granite monolith standing in the heart of the north Queensland city of Townsville. It rises to a height of some 286 metres above sea level and dominates the skyline of this relatively low level city. There are a number of vantage points from which to view the city below and also across Cleveland Bay to nearby Magnetic Island. Many people walk up Castle Hill for regular exercise. There are many different routes to the top, by road or by goat track.
