The trail refers to the city trail that can only be walked. As we all know, Chongqing is a mountain city. Unlike most cities, the alleys in Chongqing have little flat road, mostly composed of uphill steps, which is what the locals say. According to statistics from the housing and construction department, there are 57 more mature trails in Chongqing. Tourists generally go to the mountain city trail to check in. The exact name should be the third trail of the mountain city, and it is also a section of the roundabout trail. The third trail is located on the southern slope of Yuzhong District, about three kilometers long, built along the river, along the Nanjimen ridge all the way up, you can lead to Ren'aitang, and then through Gulou Lane, Consul Lane, you can go to the gun dam, Tongyuanmen, it is an important road connecting the upper and lower half of the city in the old time, and there are many ancient buildings along the way. You can check in. There are many strategies on the Internet. The regular line is entered from the entrance of Zhongxing Road Trail. The whole journey is uphill. There is also a whole downhill route starting from Consul Alley. I chose to enter from Shancheng Alley, walk around the mountain for half a circle, and return to Tongyuanmen. It feels very good. Shancheng Lane is the only century-old lane named after the mountain city in Chongqing, built in the Ming and Qing Dynasties. In 1900, French missionaries lit up the pole on the slope of this lane for passers-by lighting, hence the name Tiandeng Lane, Tiandeng Street, in 1972 renamed Shancheng Lane. Hou Yu was built in the 1930s, belonging to the typical Shanghai Shikumen architectural style, from a side reflects the history of Chongqing as a companion during the period of the War of Resistance. The building masonry structure, stone door frame, eight-shaped facing door, curved window, stone house base, built on slope, is the typical representative of the main city of Chongqing mountain building. The suspended plank road built on the steep wall is a good place to view the river view. From here, the sight is suddenly bright, the Yangtze River, the bridge, and the opposite Nanping...Unobstructed. Opposite is the Nanjimen Railway Bridge, which is very beautiful to take pictures. A hundred meters forward, I saw the pavilion sitting on the plank road, and I went to Jintangmen. Like Nanjimen, there is no city gate, only the city wall. The walls on the cliffs were still strong, but every other section there were old trees, or poking out of the gap, growing up desperately, or with long roots, wrapped a section of the wall, or a stone, showing the vitality of the vigorous. Because I came earlier, the small shop and old building next to it did not open, but so I can enjoy the entire mountain city trail. The supporting facilities of the mountain city trail are still very complete. Walk one or two hundred meters. There will be road signs on the ground and walls. There are special attractions nearby. There are also commentary cards. The whole line is down. There is no need to ask others for directions at all. It is very suitable for a person to come to citywalk. I walked from Shancheng Lane to Tongyuanmen, stopped and took pictures, it took about an hour and a half, both exercising, and familiar with the style of Chongqing, not very tired, down the mountain in the Hula noodle restaurant opposite the Tongyuanmen city wall, ate a bowl of small noodles, packed things to the airport, Draw a complete end to the trip to Chongqing, happy. After the store opens during the day, the playability here will be stronger. It is said that the night view at night will be more beautiful. If you have two hours of leisure time in Chongqing, I recommend everyone to come and take a look.
