Mouth of the Santa Ana River

After traveling over 100 miles the water flows into the Pacific Ocean near Brookhurst Street and Pacific Coast Highway.  It has traveled through an area where over 4 million people live.

There is also a bike path that runs along this river. You can ride all the way to Corona near Prodo Dam on it, a ride of 30 miles and there are plan to complete the "Crest-to Coast Trail 110 miles in all.  To check out the path see the map at
