**This outing's route shows the northern segment and can be combined with the southern segment, separated by a one-mile gap (see Helen Putnam Regional Park for the southern route map). Both outing descriptions are included below:**

In Petaluma, the 7.2-mile Ridge Trail ventures through a rural regional park and many neighborhoods and parks, including downtown; it also follows both the Petaluma River and Lynch Creek for a stretch. Northeast of US 101, you have an opportunity to explore newer neighborhoods of Petaluma. There is a 1-mile gap between Helen Putnam and the city route. The city section is an excellent bike ride; however, in May 2017 the route lacked Ridge Trail signage. This is a temporary route until the planned route along the Petaluma River, Sholleberger Park, and Adobe Creek Trail can be finished.
