Small oil pit

Xiaoyoukeng is located in the west slope of Qixing mountain, also known as sulfur Valley, which is the representative landscape of Qixing mountain. Under the strong post volcanism, the underground heat source of xiaoyoukeng is still very strong, and the sulfur jet comes out from the thinner part of the crust, hissing. Here, you can enjoy a string of crystal like, needle like, yellow, beautiful sulfur crystals, and listen to the burst sound of the jet mouth, experience the situation of post volcanic activity.

Introduction to scenic spots

Yangmingshan National Park is the back garden of the greater Taipei city. Its rich natural and ecological landscape has always been the best leisure space for Taipei people living in the urban jungle, which is closest to nature and can relieve pressure. Xiaoyoukeng is a beautiful view of the garden after that.

Xiaoyoukeng is located at the northwest foot of Qixing mountain. You can walk right from Xiaoguanyin station of Yangjin highway to the sightseeing trail, with beautiful scenery along the way. Xiaoyoukeng is more than 800 meters above sea level. Its most distinctive landscapes are volcanic vent, hot spring, collapse terrain and sulfur crystal Special natural landscape, is a best parent-child nature classroom.

Qixing mountain is located in Yangmingshan National Park. It is the highest peak of the Datun volcano group. The main peak is 1120 meters above sea level. The top of it was originally a volcanic vent, which was eroded into seven small hills for a long time. Therefore, it is named. The famous scenic spots in the area include Qixing pool, Qixing East peak, dreamlike lake, etc., while there are xiaoyoukeng, Guanyin Mountain, Datun mountain and other scenic spots around it. The park is a vast flat land, overlooking Taipei. There are simple and elegant pavilions and wide and comfortable lawns in the park for mountain climbing and walking tourists to have a rest. Here you can overlook the beauty of the nearby peaks, the confluence of Tanshui River and Keelung River, and the view of the sea.

Introduction to scenic spots

Xiaoyoukeng is a post volcanic geological landscape area, located at the northwest foot of Qixing mountain. Turning right from Xiaoguanyin station of Yangjin highway, you can reach the viewing trail, with an altitude of about 805 meters. It is characterized by blowholes, sulfur crystals, hot springs and spectacular collapse topography formed by post volcanism. For those who like to observe plants, they can also spend more than ten minutes on the nearby bamboo forest trail to observe bamboo forest, Miscanthus grassland and volcanic plants.

Xiaoyoukeng is located in the saddle of Qixing mountain. It looks like a horseshoe shaped concave Valley, a bit like a crater. In fact, it is the outlet of high-temperature volcanic gas. We call it a crater, which is the geological landscape area of Yangmingshan National Park. Standing at a high place, you can see the special conical or bell shaped volcano from a distance, and the incomplete crater which has been eroded for a long time.

Blasting crack

When yellow sulfur mineral crystals can be seen around some vent holes, this kind of vent hole is called sulfur vent, which is a common landscape in volcanic areas.

Sulfur pore

Needle like crystals can often be seen in the near view of sulfur pores. They are hydrogen sulfide (H2S) and sulfur dioxide (SO2) in the form of sulfur vapor at high temperature, which rise up and condense near the jet holes to form needle like crystals.

Crystalized Sulfur

Miscanthus sibiricus and Cyanidium arundinaceum are the most dominant plants in the vicinity of xiaoyoukeng. The dense plants form an excellent wind resistance barrier, and Miscanthus sibiricus can also grow in the environment of high heat, drought, shallow soil layer and sulfur gas. On both sides of the trail are associated with chestnut fern, pyrophyllum, Viola Taibei and other positive plants. As for the hot fog area inside the crater, only sulfur fungus (an Archaea), algae, lichens and mosses can grow.

Volcanic plants: lichen, moss and chestnut fern

Herbs: Miscanthus formosana, Cyanidium arundinaceum, ageratum conyzoides, Eupatorium adenophorum, Ranunculus japonicum, Plantago asiatica, Prunella vulgaris, Eupatorium adenophorum, typhoons herb, red chariot messenger of Alishan Mountain, centipede fallen to the ground, Cymbidium imbricatum, Viola Taibei, Osmunda japonica, Pteris nipponica, Dryopteris NEPHROLEPIS, gymnopteris, Dryopteris

Loading wood: Rhododendron Pinghu, Rhododendron baihuaense, Rhododendron pink, Rhododendron yuehuaense, Rhododendron yanziense, Rhododendron bailianjin, eight immortals with narrow petals, Rhododendron dengchenghuae, Eurya and Eurya pseudomorpha

Arbors: kunlan tree, Phoebe bournei, Ficus microcarpa, Ailanthus altissima, Prunus nigricans (Prunus nigricans)

Vines: Celastrus angustifolia, Herba pyrophyllae, papyrifera Taibei, Rubus variabilis, and Rubus Rubus

Xiaoyoukeng area is located in the northeast monsoon area, the vegetation succession rate is relatively slow, and it is still in the positive herb stage (Miscanthus, Fargesia) in the early stage of succession, and some clumps can be seen in the more humid places. The bird species in this area are mainly in the forest edge and clumps at low altitude, and the thrush family is the dominant species.

Volcano eruption

After the eruption of the Tatun Volcano in Northern Taiwan stopped, geothermal gas carrying strong acid and sulfur gas erupted continuously to the surface through the fault, causing the volcanic rocks to corrode and collapse, forming the present volcanic geological landscape of collapse and white smoke. According to historical records, as early as in the Wanli period of the Ming Dynasty, people sailed to this area to exchange materials for sulfur. Up to now, many people still call it "sulfur Valley".

Surrounding scenic spots

In addition to xiaoyoukeng, nearby scenic spots include Zhuzhu mountain, Qixing mountain, Datun mountain and Xiaoguanyin mountain. There is an attached tourist service station in xiaoyoukeng recreation area, which provides services and materials such as guide, interpretation, etc. for your reference.
