The park serves a dual purpose as a functional flood-plain reservoir during the typhoon season to prevent inundation in urban Sanchong.
It is part of a 200-kilometer continuous riverside cycling network encompassing the Tamsui, Keelung, and Xindian rivers.
The Tamsui River estuary is a critical habitat for mudskippers and fiddler crabs, often visible from the park’s edge at low tide.
The park footprint is reclaimed land originally part of the Tamsui River's natural alluvial sediment banks.
Sections of the park were specifically engineered to align with the 'New Taipei City Riverside Greenway' project to integrate environmental conservation with recreation.
Tamsui Riverside Park in the Sanchong District is a multi-purpose recreational zone stretching along the western bank of the Tamsui River. The park is characterized by its extensive network of dedicated cycling paths that connect to the wider New Taipei City riverside trail system. It features varied sports infrastructure, including basketball and tennis courts integrated into the waterfront landscape. The area serves as a flood detention zone, which influences its open-field design and lack of dense vertical structures. It offers unobstructed views of the Taipei skyline across the river, particularly toward the Datong and Zhongshan districts. The park infrastructure is maintained by the New Taipei City Government’s High Riverbank Construction Management Office.

Carry your own water, as vending machines are infrequent along the extended riverside stretches.

Access to specific segments may be restricted during periods of heavy rainfall or typhoon warnings when the river level rises.
Cyclists must yield to pedestrians; sports courts operate on a first-come, first-served basis unless reserved through official municipal systems.
