4. MacKerricher State Park, California
Sea glass may not be considered a treasure by pirates, but it’s definitely something precious for most tourists.
Did you know that Fort Bragg’s MacKerricher State Park hides an entire stretch of sea glass? One century ago, locals used to throw old bottles in a dump along the coastline. However, now, with the help of Mother Nature, we can enjoy this marvelous place.
But, unfortunately, we can’t take a piece of it home, as it’s illegal.
