The Pingxi Railway in New Taipei has some of the most popular attractions in Northern Taiwan. With a total of 7 stations (plus 2 if you count Ruifang and Houtong), there are endless places to explore, eat, hike, and enjoy Taiwan's history, culture, and natural beauty all in one place. 

Background:
Before the Pingxi Railway was built, during the Qing Dynasty a section of the Danlan Old Trail ran through roughly the same area, connecting Yilan to Tamsui.  The Japanese completed the Pingxi Railway in 1921 in order to transport coal from the area. Most all of the stations and villages along the line were economically reliant on the coal industry until its downfall in the late 1990s. 
The coal industry remained strong after the ROC took over Taiwan after WWII, but slowly waned in the 1980s and 1990s due to the decrease in global coal prices. 
In the year 2000, Sanxia’s Lifeng Mine shut down operations, and Taiwan’s mining company closed, and thus all coal mining in Taiwan effectively stopped.
The Pingxi Railway is a single track that is 12.9 KM long with 7 stations. 
Recently the government has offered many plans to connect the Pingxi Railway to the Taipei MRT via Jingtong to Jingmei, however due to many factors these plans have never been approved. 
The area around Pingxi and Ruifang is made up of sedimentary rock which easily erodes, creating many large waterfalls such as Shifen Falls, and pointy jagged peaks like the Pingxi Crags. 
Popular activities along the Pingxi Railway include hiking, river tracing, eating at one of the many old streets, setting off sky lanterns,  and exploring the many historical coal mining sites.

Hours:
The first train reaches Sandiaoling daily at 5:25 AM and the last train leaves Jingtong at 8:33 PM.

Price:
80 NT per person for a one day pass

When to go:
Any time of year is great. However, waterfalls are most enjoyable during the hot summer, and you may want to come for lantern festival when hundreds of sky lanterns are set off at once.
To avoid crowds and packed trains, do not go on weekends or holidays. 

How to get there:
By Train: Take the TRA to Ruifang Station, buy the Pingxi Railway line one day pass, and then switch to the Pingxi Railway line. Get off at any station!
By Car/Scooter: Take provincial highway 2 east toward Pinglin, then get off the main highway once you reach Shifen. You can drive right or left to reach all of the stations on the Pingxi Railway line. But please know there is limited car parking around the stations.

The Pingxi Crags are a set of hiking trails that traverse steep mountain peaks and rock cliffs in the mountains south of Pingxi Village. The sedimentary rocks here stick out of the forest at the tops of the mountains, making for great views but also dangerous climbs. 

Background:
The rock formations that form the Pingxi crags hike formed as sediment under the ocean millions of years ago and were then uplifted thanks to the collision of the Eurasian and Phillipine plates. The rocks are mainly sedimentary and are part of the same formation that forms the special rock formations on the northern coast around Keelung.
The area also has some coal deposits, and there is an abandoned mine on the trail. 
There are basically six main peaks along the Pingxi Crags trail: Xiaozishan (孝子山), Cimu Peak (慈母峰), Cien Peak (慈恩嶺), Putuoshan (普陀山), Choutoutshan (臭頭山) and the Zhongyangjian Peak (中央尖)  which is the highest peak in that chain of mountains. 
Xiaozishan is 140 (459 feet) above sea level.
Much of the climbing is medium to difficult, and includes rock scrambling and rope climbs up steep cliffs with carved steps and footholds, as well as ladder crossings and chain ladder climbs in some places.
The area is popular with hikers and can get busy on the weekends. 

Hours:
24/7

Permits Required:
None

Duration:
The trail is technically 1.6 KM to Zhongyanjian, but it could take you most of the day because the hike is steep and there is lots of rope climbing. The difficulty here is medium because you are not gaining tons of elevation but there are some really scary rope climbs, rock scrambling, and near vertical rock climbs in some places. 

When to go:
On a sunny dry day. The rocks can get slippery and a fall on some of the trails could kill you. 

When not to go:
Don't go when it is raining. You could slip right off a cliff to your death, plus it will be cloudy with no good views. Don't bring children under 12 years old. 

How to get there:
By Train: Take the TRA to Ruifang Station, and then switch to the Pingxi Railway line. Get off at Pingxi Station, and then walk south past the river toward the mountains. The trailhead starts right to the right of the public bathroom.
By Car/Scooter: Take provincial highway 2 east toward Pinglin, then get off the main highway once you reach Shifen. Then turn right and go west on county road 106 until you reach the Pingxi Old street and turn left up the mountain after you reach the Taiwan Power Company. There is a parking lot and trail head at the end of the road.

Ximending is a historical neighborhood and shopping district in west Taipei. Originally built by the Japanese as an entertainment district, it later became the first designated pedestrian zone in Taiwan. Here you can find night market like food choices, historical sights, and endless shopping options. It is definitely worth a stop on your trip to Taipei.

Historical Background:
The land that Ximen Shopping District stands on was once part of Basay tribal land. The Basay people had lived on the land for thousands of years before the first Chinese settlers.
Sections of the area indicate that there was settlements here during the Dutch rule in the 1600s.
The name Ximending refers to the neighborhood just outside the west gate of Taipei City. Before the Japanese colonization of Taiwan, this area was wilderness connecting Taipei with Bangka. The Japanese decided to develop it into an entertainment area around the turn of the 20th century.  The walls of Taipei were later torn down in 1905. 
One historical building here is the Red House Theater (紅樓劇場) which was built in 1908. Originally the building was a department store, but after 1945 the building was transformed into a theater. After a fire in the year 2000, it was renovated and turned into a museum with shops and theater with more modern equipment. 
In the year 2000, Ximending was designated as a pedestrian zone, the first in Taiwan.  Because if its popularity, the area is also known for more crime and illicit activities. 
Currently the area sees over 300 shoppers per month. The area is also especially popular with young people because there are many high schools and cram schools nearby.
