SUNDAY, FEBRUARY 27, 12-3PM Join a park naturalist as we attempt to explain the origin of our coastline’s Sea Caves and Arches – an adventurous and photogenic hike along a seldom visited shoreline. Expect some moderate rock scrambling as we head to Little Treasure Cove to explore. Meet at Pelican Point lot #1 (PCH coastward at Newport Coast, right at the kiosk to the last lot). Day-use fee: $15
