仙霞关, Mountain pass in Jiangshan City, China

Xianxia Pass is a fortified mountain pass in Bao'an Township, Jiangshan, Zhejiang, on the Xianxia Ancient Road over the Xianxia Ridge. Four stone gatehouses and about five kilometres of granite-paved road survive, forming the best-preserved site of the late Tang Huang Chao uprising. It is counted among China's four great ancient passes, with Yanmen, Hangu and Jianmen.

Xianxia Pass is the best-preserved site of the late Tang Huang Chao uprising, with four surviving gatehouses and five kilometres of granite-paved road. In the Nanming period, Longwu regime troops defended it against Qing forces advancing on Fujian. In May 1942, the 105th Division held three defensive lines here; over ten days of fighting, Chinese troops repelled the Japanese at a cost of over 500 casualties while killing more than 1,000 enemy soldiers. It was listed as a Zhejiang provincial cultural relic in March 1963 and merged with the Xianxia Ancient Road under that name in 2011.

Xianxia Pass was one of the six Xianxia gates, together with Anmin, Erdu, Mucheng, Huangwu and Liushi, and is counted among China's four great ancient passes alongside Yanmen, Hangu and Jianmen. The name Xianxia refers to the immortal mist of the ridge. The site was originally listed in March 1963 as the Huang Chao Uprising Site at Xianxia Ridge and was merged with the Xianxia Ancient Road in 2011 under the name Xianxia Ancient Road.

The stone paths involve steep sections and can be slippery after rain, so sturdy footwear is a must. Going in the morning tends to give you cooler air and fewer people on the narrower stretches of the route.

The pass is one of four great ancient gates of China, alongside Yanmen, Hangu and Jianmen. It was also the first of six passes — with Anmin, Erdu, Mucheng, Huangwu and Liushi — known as the Xianxia Six Gates. Four gate houses and five kilometres of granite-slab road survive.
