When the sun goes down, parks close, but the natural world still teems with activity. At Parks After Dark: Good Night Moon, families can enter that world and explore Santa Rosa’s Spring Lake Regional Park at night. Kids will learn about wildlife, hear stories around a campfire, visit the Environmental Discovery Center, and hike by moonlight near the lake. The event will be held on October 6, 6:30–8:30 p.m. Admission is $10–$12; registration is required. For more information and to sign up, see tinyurl.com/ytjh27e2.
