If you start from where the bottom of the mountain begins in Azusa,, which (Hwy39)The San Gabriel river trail would start across from San Gabriel Canyon Gateway center ..if stay on this trail due South,, you will pass the golf course (Pico Rivera) & liberty Park (Cerritos) & you will end up in Seal Beach & the dockside of the marina along a yatch club & many restaurants.
From where to where? The road starts within the mountains and ends at the beach. There are also several roads that ends in different places.
