The Annual Art in the Park is sponsored by the Petaluma Arts Association, which has been an active part of the community for decades. Over two days at the beginning of September, local artists display their works at Walnut Park. Discover a range of genres such as paintings, photography, jewelry and textiles. Some of the artists will even make art while you're there, demonstrating their craft and expertise. Net proceeds from Art in the Park go towards grants for art curriculum in Petaluma's public schools as well as Santa Rosa Junior College.
