Mount Lidgbird, also Mount Ledgbird and Big Hill, is located in the southern section of Lord Howe Island, just north of Mount Gower, from which it is separated by the saddle at the head of Erskine Valley, and has its peak at 777 m above sea level. The trek to the summit is for expert climbers only. Ropes are needed to scale the cliffs and slippery, steep terrain. In comparison, Mount Gower is an easy hike. Halfway up the mountain is Goat House Cave, a former shelter for 19th-century Kentia palm gatherers. From this spot, visitors can see nesting masked boobies and numerous red-tailed tropicbirds.

Etymology

Mount Lidgbird is named by the naval officer Captain Henry Lidgbird Ball in honour of his father, George Lidgbird Ball. Ball junior first sighted Lord Howe Island in 1788 while he was on his way to Norfolk Island in the ship HMS Supply. He also named the nearby rock outcrop Ball's Pyramid.

Flora

Cryptocarya forest, one of two types found on the island, the other being palm forest, is found in patches on the slopes of the mountain between elevations of 350 to 600 m above sea level. Palm species growing on the mountain include Hedyscepe and Lepidorrhachis.
