"Alangyi" originates from the old name of the Paiwan tribe's Alangyi (Anshuo) settlement, which literally translates to "the gradual shrinking of vast things," and was already documented in relevant literature during the Kangxi period. This ancient trail was a strategically crucial location contested by military strategists, where the Puyuma, Paiwan, and Amis tribes had all migrated through, serving as a testament to the era of migration. Historically, once ascending the hills, travelers had to be exceptionally cautious, as headhunting (out-of-grass) could occur at any time.

The ancient trail originally spanned a total length of approximately 200 kilometers. At the end of World War II, the Japanese military blew up the roadbed of the ancient trail to prevent American forces from landing at Mudan Bay. As a result, only about 4 kilometers of the coastline currently remain. Due to the long-term impact of military control, the ancient trail has seen relatively little foot traffic. The trail preserves its pristine appearance, becoming a representation of Taiwan's primitive geology and landforms. It is also one of the few primitive coastlines in Taiwan where no highway has been opened. This section of the coastline is currently one of the few areas in Taiwan without highway access and has been officially announced and designated as the "Xuhai-Guanyinbi Nature Reserve." The ecological environment is well-preserved, boasting rich flora and fauna resources.
