Iceland's coastline, approximately 4,970 km (3,086 mi) long, is highly varied. Fjords, carved by glaciers, deeply indent the western and northern regions, creating dramatic landscapes. Black sand beaches, volcanic in origin, contrast with stretches of dramatic cliffs. The coastline is rich in biodiversity, supporting numerous bird species and marine life, including whales and seals. Significant portions remain relatively untouched, offering opportunities for hiking, wildlife viewing, and exploration. Coastal erosion is a significant ongoing process, shaping the constantly evolving landscape.
