Yangmingshan National Park is one of the nine national parks in Taiwan, located in both Taipei and New Taipei City. The districts that are partially in the park include Taipei's Beitou and Shilin Districts; and New Taipei's Wanli, Jinshan, Sanzhi and Tamsui Districts. The national park is known for its cherry blossoms, hot springs, sulfur deposits, fumaroles, venomous snakes, and hiking trails, including Taiwan's tallest dormant volcano, Qixing Mountain rising to 1,120 m (3,675 ft).

Taipei, officially Taipei City, is the capital and a special municipality of Taiwan. Located in Northern Taiwan, Taipei City is an enclave of the municipality of New Taipei City that sits about 25 km (16 mi) southwest of the northern port city of Keelung. Most of the city rests on the Taipei Basin, an ancient lakebed. The basin is bounded by the relatively narrow valleys of the Keelung and Xindian rivers, which join to form the Tamsui River along the city's western border.
