Enjoy a guided interpretive 2-hour Almost Full Moon Hike at Crystal Cove State Park to explore the twinkling stars and the night sky. A park naturalist will lead hikers on this moderate to difficult 4-mile loop trail with uneven terrain and a steep uphill climb. Wear sturdy shoes, bring water, dress in layers, and bring a red flashlight (if you have one). All hikers must stay as a group with the park naturalist and must be at least 8-years old. Meet at the Ranger Station (PCH inland at stoplight School-State Park follow the signs to the Ranger Station.)
