California beaches are covered with colorful stones tumbled smooth by the ocean. They come in all possible types, shapes, sizes, and colors. You see them shining in the wet sand or scattered across the gravel, and you might be tempted to pick one or preferably more. Few are strangers to that feeling, but on most California beaches, giving in to this temptation will equal breaking the law.
Among the coastal states of the U.S. West, California has the strictest rules regarding coastal rockhounding, regardless of how accessible a particular part of the coastline is to the general public.
Rock and material removal is more strictly regulated and enforced in California than in Oregon, Washington, Alaska, or Hawaii. Collecting without permission can lead to fines, even if you only take a few small stones. Before you bend down to grab that bright agate, make sure you know the rules that apply to it.
If a beach is part of a State Park, State Beach, National Park, Coastal National Monument, Marine Protected Area, or other protected land, taking rocks or other natural materials is illegal.
Only a few beaches on the California coast still allow rock collecting. Even where collecting is permitted, it is limited to a small amount for personal use—usually about 15 pounds per person per day. This is also generally restricted to loose material in the wave-washed zone.

Glass Beach in Fort Bragg is a notable example. It is a famous spot known for the coastline covered with sea glass. You cannot legally collect it, though. Most of the Glass Beach lies within MacKerricher State Park, where removal of sea glass is prohibited. Some nearby stretches outside the State Park may have loose sea glass visible at low tide. Checking current regulations and posted signs before taking anything would be our standing advice for such instances.
Another example is Moonstone Beach, which is known for smooth, yellow, milky feldspar called "moonstone." The beach is protected, and visitors may admire and photograph the stones, but removing them is prohibited.
Why Rockhounding Books List California Coast Sites as “Public Collecting Areas”
You might notice that many California rockhounding guidebooks, even recent ones, contain misleading information about coastal collecting, leaving the readers fairly confused. More often than not, the authors rely on inaccurate or outdated information. Through oversight or the sheer speed of law creation, the legal information in those guides may be inapplicable.
Even this article is as good as the information available at the time of publication. California's coastline is complex, and laws change fast – make sure you are complying with the rules that are in force at the time you are reaching down to pick up that fancy stone.
Some beaches that previously allowed limited collecting could have become State Parks, State Beaches, or Marine Protected Areas – and, hence, the removal of rocks is no longer allowed. Rules can be especially confusing when one beach is managed by several different agencies, each with its own regulations. You might be allowed to collect in one section of the beach and may not be allowed in another section of the very same beach.
For that reason, tread carefully (literally and metaphorically), and do not assume that the location listed in your guidebook as good for rockhounding is actually good for rockhounding. Instead, use the book as a starting point and confirm the current rules yourself.
Before visiting any site, look up the current managing agency and contact park or land management staff if anything is unclear.
When you arrive, always check posted signs.

Key Notes for California Beaches
Most California beaches are protected, and taking agate, jasper, petrified wood, sea glass, shells, or other natural items is illegal.
Where allowed, collecting is limited to loose stones in the wave-washed area and small personal amounts, usually about 15 pounds per person per day.
Contact land management officials and read posted signs before collecting rocks, even at beaches listed in guidebooks.
