The Fluvial Park of the Region of Pamplona or Arga Fluvial Park, is a green corridor that serves as a refuge for natural life, protects the river environment of the Arga from the pressure of the urban environment, improves the landscape perception of the Region and offers an important communication route for use on foot or by bicycle.

It is located in a part of the route of the Arga, Ulzama, Elorz and Sadar rivers, which flow through the Metropolitan Area of ​​Pamplona, ​​Foral Community of Navarra, Spain. The park's river walk currently has three routes:.

On January 12, 2000, the town councils of Burlada, Villava, Huarte, Zizur Mayor, Barañáin, Egüés, Ezcabarte, Esteríbar (through whose municipal boundaries the Arga River runs), with the Government of Navarra and the public company NILSA, formed the River Park Consortium of the Pamplona Region, thus laying the foundations for the rehabilitation of the banks of the Arga and its tributaries in the area of Pamplona: the Ulzama, Sadar and Elorz rivers.[2]​.

In 2006, in order to face the integral water cycle in a comprehensive and coordinated way, the Consortium passed the management of the river park to the Commonwealth of the Pamplona Region, which has managed the maintenance and expansion of the park since 2007.[2]​.

In 2014, the main route ended in the Señorío de Eulza, in the municipality of Barañáin, until the new promenade to Arazuri was built. Since then, several expansions have been planned in the park's routes.

In 2021, the route corresponding to the Arga River was extended by 5 kilometers, with the incorporation of two new walkways, from Arazuri to the town of Ibero "Ibero (Navarra)"), passing through Ororbia. In the future it is planned that this route will reach both Etxauri and Ciriza.

Since that same year, the river walk has been extended along the Elorz River, to the mouth of the Sadar, and from there, upstream, passing through the campus of the University of Navarra, to that of the Public University of Navarra.[3]​.
