About this site
Arena Cove sits at Point Arena on the Mendocino coast of Northern California, near the town's historic pier. It is a beginner-level dive with a maximum depth of around 15 metres, making it a relatively approachable entry point along a stretch of coastline otherwise known for exposed, rugged shoreline diving.
