Mount Gower is the highest mountain on Australia’s subtropical Lord Howe Island in the Tasman Sea. With a height of 875 m, and a relatively flat 27 ha summit plateau, it stands at the southern end of Lord Howe, just south of the island’s second highest peak, 777 m Mount Lidgbird, from which it is separated by the saddle at the head of Erskine Valley. Ascending Gower entails a popular, guided, strenuous 8-hour return hike, though no special climbing skills are needed.
