Where Parks meet the sea

Bird’s eye view of Point Reyes National Seashore spacer image The narrow strips where the land meets the sea - coastlines - are among the most dynamic environments on Earth. Relentless attack by waves gnaws away at even the hardest of rocky coasts, reshaping the shore with each passing wave. Even the most gentle waves change the shape of the shoreline each day in imperceptible ways.
