The spectacular pinnacle known as Lighthouse Tower, or as it is sometimes called "Cleopatra's Needle," rises over 75 metres from a ridge which extends to the east of the highest part of Mount Saskatchewan. It may be seen from a pull-off 4.9 kilometres to the south of the Alexandra River Flats Viewpoint and this is also the best spot for a view of Mount Saskatchewan. Another view of the Tower is through a gap in the ridges 5.2 kilometres north of the viewpoint and although the spire is much closer and still spectacular, it is not nearly as "needle-like" as it is from the south.
Lighthouse Tower was first climbed in 1964.
