Last Saturday, I went on a pretty bike ride starting in Petaluma along Chileno Valley Road to the coast and then back. It was a perfect day! Along the way, I saw cows, horses, an alpaca, bunnies, a turtle, goats, sheep, a snake, black birds with bright red cheeks, blue jays, carniverous looking birds with huge wing spans and some other animals I’m forgetting right now. The ride was 56 miles with about 1,800 feet of climbing, so it’s sort of long but not overly strenuous.
Here’s a map and route directions for anyone else that wants to go!

Driving Directions to Starting Point
Take the 101 North to Petaluma and exit Petaluma Boulevard South. Drive north 2 miles and make a left (west) on Western Avenue. Drive 2.2 miles and then turn left on Chileno Valley Road. Drive .8 mile to Helen Putnam Regional Park on the left. (the sign for the park is facing the opposite way so it’s easy to miss…if you go more than 1 mile after you get on Chileno Valley Road w/o seeing the park, turn around and you’ll be sure to see it. It costs $5 to park in the small lot but you can also park on the opposite side of the road for free).
