Estuary Beach

Where river meets sea — rich, firm digging ground

Sandy or silty beaches at river mouths and estuaries. The mix of river sediment and marine sand creates a rich, firm digging medium that holds shapes extremely well. Water seeps in from multiple directions, making it easy to fill channels and moats. Often less crowded than traditional seaside beaches.
