This is the Lynnmere Trail in Thousand Oaks and its best to ride it as a loop which is about 6 miles long. Its up and down the entire ride so if you are the up all the way and then down kind of person then this trail might not be for you! This video contains mostly the downhill sections of the entire loop.
