The Rock and Alpine Garden lies on the south-west corner of Government House, on the outcropping of rock below the swimming pool.

This garden features choice plants from the mountainous areas of the world. Many of the plants in this garden were started from seed and obtained from the Alpine Garden Society, London; The Scottish Rock Garden Club, Edinburgh; and the Alpine Garden Club of BC, Vancouver.

A Heather Garden is located at the base of the Rock and Alpine Garden.
