Santiage Creek Bike Trail

Santiago Creek Greenway Alliance 

Working Toward a Greener Creek

Who We Are

A Public Benefit Nonprofit 501(c)(3)

We are a group of volunteers dedicated to improving public use of the Santiago Creek.  The Santiago Creek begins in the mountains above Irvine Regional Parks in the City of Orange and flows through Villa Park and Santa Ana to the Santa Ana River.  From the moment we started our work in 1991, we understood that by working together we could achieve our mission to improve the beauty and access to Santiago Creek.

What We Do

Our Mission is to create a greenway and trail system along the general course of Santiago Creek and to preserve and enhance its ecological scenic, historical and recreational resources.
