The name "Guan Du" comes from the Spanish word "Casidor." Because the Japanese omitted the "S" when pronouncing it, it became today's "Guan Du." In ancient times, Guan Du was once a sulfur production and export center. In 1895, it was a military fortress with cannons and even suffered a meteorite attack. Remnants of what is believed to be a meteorite are still left in the Guan Du Primary School's Ziqiang Branch.
Guan Du Riverside Park is vast, with pedestrian paths and bicycle paths. Guan Du Wharf is also one of the boarding points for the "Blue Highway" routes, which go to four different routes: the Taipei Daichi Pier, the Beitou Old Street, the Baoli Left Bank, and the Fisherman's Wharf. From the bicycle path along the Guan Du River, you can head north to the Beitou Fisherman's Wharf or south to the Jisuo Island on the Keelung River, forming a beautiful scenic route.
Here, there are rich intertidal zone ecosystems for observation and research. Afternoon, dusk, and night each have different appearances and scenery, especially the riverside scenery of the Tamsui River, the beautiful sunset view of the Guanyin Mountain in Bali, and the dazzling lights on the wharf at night.
