No, it is strictly illegal to take sea glass from Glass Beach in Fort Bragg, California. The beach is part of MacKerricher State Park, and state law prohibits the removal of any natural or cultural materials from park grounds. While the beach was once a municipal dump where glass bottles were tumbled by the ocean into smooth, colorful treasures, decades of tourist "poaching" have led to a massive decline in the glass levels. Signs are clearly posted at the entrances warning that all glass must stay on the beach so that future generations can enjoy the unique landscape. In 2026, park rangers frequently patrol the area, and fines for removing glass can be significant. If you are looking for sea glass to keep, locals suggest visiting smaller, non-protected coves in the surrounding Mendocino County area where collection is not prohibited, but at the main Glass Beach, the rule is strictly "leave no trace" to preserve what is left of this historic man-made phenomenon.
