Glass Beach is a beach adjacent to MacKerricher State Park near Fort Bragg, California, named from a time when it was abundant with sea glass created from years of dumping garbage into an area of coastline near the northern part of the town.
The glass comes from the fact that this area was a dumpsite for trash in the early to mid-1900s, and over the years, the ocean flattened and broke down the glass to what it is today.
There’s an old myth that every time a sailor was lost at sea, mermaids would cry and their tears would wash onto the shores as sea glass. The story began with a mermaid who loved a sailor from afar and tamed the stormy sea to save his life. Neptune was incensed and banished her to the depths. Since then, her mermaid tears wash up as sea glass — mementos of unrequited love. In truth, the origins of the Fort Bragg sea glass are far more mundane.
About 1,000 to 1,200 tourists visit Fort Bragg's glass beaches each day in the summer. Most collect some glass. Because of this and also because of natural factors (wave action is constantly grinding down the glass), the glass is slowly diminishing. There is currently a movement to replenish the beaches with discarded glass.
Also, Glass Beach is much more than just a beach to find sea glass treasure. There are many other beautiful beaches and small coves there that you can explore. On low tide days, you can do tide-pooling and search for sea anemones, crabs, and more.
