Despite Taiwan being a tropical island, it also has a surprising amount of sand dunes. The Guanyin Caota Sand dunes in Taoyuan are Taiwan's longest stretch of sand dunes, over 8 KM in length. They have become a major Instagram selfie location due to being such a unique geological feature so close to Taipei.

Background:
The sand dunes at Caota have been forming for thousands of years, thanks to silt being washed into the ocean from the Taoyuan plain from nearby rivers, such as the Shunagxikou River (雙溪口溪). 
Recently, wicket fences have been placed around the sand dunes to prevent erosion and the spread of sand in unwanted places. Also, in the past few years, many land-based wind farms have been erected here.
The dunes are part of Guanyin Coastal Recreation Area, which includes a beach that may or may not ban swimming, but you can wade here, go Stand Up Paddleboarding, or surf.
Recently the sand dunes have become a hot spot for Instagrammers, but the area is still usually free of people even on weekends due to the lack of convenient transportation.

Xinwu Green Tunnel (aka Xinwu Green Corridor 新屋綠色走廊) is a popular cycling path along the west coast of Taoyuan through a belt of trees that resembles a green tunnel. Here you can enjoy the landscape, find roadside food options, and also understand more about the culture and history of the area. It is one of the most popular cycling destinations in northern Taiwan. ​

Historical Background:
Since prehistoric times, the area around Xinwu was home to indigenous Taiwanese plains aborigines. There was no large-scale Dutch or Chinese settlement in the area during the Dutch rule of Taiwan.
During the Qing Dynasty, Chinese settlers began to settle the area and begin farming. One prominent family that came to settle in Xinwu was the Fanjiang family. Later, the clan expanded further and further inland and created new homes, Qixinwu (起新屋) in Chinese, and the name Xinwu for the area stuck. 
You can still visit the Fanjiang Family's ancestral home dating back to the Qing Dynasty in Xinwu, however, it is not covered in this blog. 
Yong-an Fishing Harbor was established in 1953 and is a secondary-class port. Before that, it was known as Kaotouwu Port (崁頭屋港) which dates back to the 1800s during the Qing Dynasty, located on the north side of the mouth of the Shezi River.
Originally a small fishing port, Yong-an Fishing Port has expanded over the years, including dredging channels and extending to allow for larger fishing vessels. 
The Xinwu bike path is about 4 KM long and takes about 2-3 hours to complete. 
The area is usually busy on holidays and weekends.
