Niles Canyon is in Fremont. It's about a 15 minute ride but there's a couple more turns on the backside that I could strecth it out to about 30 minutes up and 30 minutes back.
It sure Is It is right off mission blvd in fremont and takes
you to 84 or 680. Polmares is right off the caynon enjoy
the rich people living out there.
