Join us for a nocturnal walk to celebrate the first day of winter on the shortest day of the year. Experience the day turning to night while we wait for the sounds of night creatures. Let your eyes, ears and touch all adjust to the oncoming darkness in a safe environment. Bring your sense of adventure and curiosity. Free. Parking $7 or free for Regional Parks members. Registration is required. For more information, contact Katja Svendsen by email at Katja.Svendsen@sonoma-county.org or by phone at (707) 539-2865.
