Mount Nelson is where the Signal Station was built in 1811 to announce the arrival of any ships sighted. It was linked with other signal stations, so that a message could be passed between here and Port Arthur within twenty minutes.
Inside the tiny old Station building, you can learn the codes used for the signals. There is an excellent view from here and a tearoom is available. There is also a walking track, so that you can, if you wish, take the bus up its twisting route and return on foot down the slopes of the mountain. Take bus no. 57 or 58 to its terminus to reach the top of Mt. Nelson.
