Mount Kitten, Mountain summit in Ziyuan County, China.

Mount Kitten (Mao'er Shan) is the highest peak in Guangxi, rising 2,141.5 m on the border of Ziyuan and Xing'an counties, about 80 km from Guilin. It belongs to the Yuecheng Mountains, part of the Nan Mountains, and is protected as a National Level Nature Reserve.

Kitten Mountain is the highest peak in Guangxi at 2,142 metres, formed in the Neoproterozoic Era. On 31 August 1944 a US Army Air Corps B-24 Liberator crashed on the mountain after bombing Japanese warships off Taiwan; its ten crew were listed missing for 52 years until two local youths searching for medicinal herbs found the wreckage in 1996.

The Chinese name Mao'er Shan means "Kitten Mountain", after the peak's supposed resemblance to a crouching cat. The mountain is also called "the highest peak of South China" (Huanan di yi feng) because its 2,141.5-metre summit is the tallest in Guangxi and the Nanling range. It lies on the border of Ziyuan and Xing'an counties, so people on both sides share the name and the landmark.

Good footwear and enough water are necessary before setting out, as the terrain can be steep in sections and the weather can change quickly. Starting early in the day gives more time for the ascent and avoids the strongest heat on the exposed parts of the trail.
