How to Start Beachcombing: A Beginner's Guide
Half the beaches documented on this site prohibit beachcombing — at most a handful of empty shells — and the line between a beach where you can fill a bag and one where you can't pocket a pebble is usually invisible. Check who manages the stretch, then plan around the tide table and the last storm rather than the clock.
At a Glance
2–3 hours, timed to start an hour or two before low tide
Time commitment
Low physically; the skill is reading tides, storms and land-manager boundaries
Difficulty
$0–$30 — a free tide table, a mesh bag and a small hard container for anything fragile
Starting cost
Winter to early spring after storms on Pacific beaches; any season's low tides elsewhere, minus nesting-season closures
Best season
The assumption that ruins more first trips than any other is that a beach is a beach: public sand, so anything loose on it is fair game. On the eight beaches this site has documented so far, that holds on four and fails on four: four prohibit beachcombing, two of them allowing nothing beyond a handful of empty seashells. On Oregon's ocean shore, the Beach Bill lets you take loose agates, shells and sea glass for personal use within a daily and yearly limit (Agate Beach). A few hours north, Olympic National Park's beaches allow no rocks, glass or driftwood at all, and only a handful of empty seashells per person per visit (Ruby Beach; see our 36 CFR 2.1 guide). California's famous Glass Beach is inside a state park where taking the glass is prohibited (Glass Beach).
Nothing on the sand tells you which kind of beach you're on. The answer comes from who manages that exact stretch — a state beach program, a national park, a state park, a wildlife area, a private owner — and it can change at a headland or a creek mouth. That's the first thing to check, before tides, gear or technique. Everything below assumes you've already confirmed the stretch you're walking allows collecting.
What to look for, where it collects, and when
| Material | Where on the beach | Best conditions | Rule to check first |
|---|---|---|---|
| Agates and jasper (Pacific Northwest) | Gravel beds and cobble bands exposed when sand is stripped, and where creeks cross the beach | Winter and early spring, at low tide, right after a storm has scoured the sand | Oregon's Beach Bill allows loose surface material only, within a gallon a day and three gallons a year; nothing in National Park Service units |
| Sea glass | The wrack line and gravel pockets, often near old towns and historic dump sites | After storms, on the first low tide | Glass Beach in Fort Bragg is a state park where taking it is prohibited |
| Shells | The high-tide wrack line and the lower beach on a falling tide | The first low tide after onshore wind or a storm | Living animals are protected in many places — on Sanibel, that includes sand dollars, sea stars and urchins |
| Quartz pebbles ("Cape May diamonds") | The surf line and gravel at the water's edge | Low tide, after rough water has turned over the gravel | Sunset Beach is private and welcomes collectors; the state wildlife area and state park next to it do not |
| Driftwood | Above the high-tide line and in log piles | After winter storms | Some state parks restrict wood removal entirely — Washington's Birch Bay requires a permit for wood debris |

Your first beachcombing trip, start to finish
- 1
Confirm who manages the exact stretch
Look up the beach on this site or on the managing agency's own page. Note where the boundary sits — a headland, a creek, a parking-lot sign — because the rule changes there, not at the county line.
- 2
Pick the day by the tide table
Find a low tide in daylight; a minus tide, one that falls below the local mean lower low water mark, exposes the most beach. NOAA publishes free tide predictions for coastal stations.
- 3
Arrive an hour or two before low tide
That gives you the falling tide to follow the water out and time to work back before it turns. Watch the water for a few minutes before you walk out.
- 4
Walk the lines, not the middle
Work the wrack line (the band of seaweed and debris the last high tide left), then the lower beach and any exposed gravel. Wet stones show their color and translucency better than dry ones, so look where the sand is still damp.
- 5
Check everything you pick up
Make sure a shell or sand dollar is empty before it goes in the bag, and put back anything alive. Stay inside the stretch's limits if it has them.
- 6
Leave before the tide traps you
Know your way off the beach before the water turns, especially below cliffs or around points that flood at high tide.
On Pacific beaches, the ocean is the real hazard
The National Weather Service warns that sneaker waves can run at least 150 feet up a beach into the dry sand, and that there can be 10 to 20 minutes of small waves right before one hits. The same waves lift and roll driftwood logs that weigh hundreds of pounds. Watch the water for at least 20 minutes before you settle in, never turn your back on it, never stand or sit on beach logs, and keep well back from the waterline in winter — exactly when agate hunting is best.
Read the tide table before the forecast
Tide heights are measured from mean lower low water, so a minus tide (shown as a negative number) uncovers ground that's underwater on an ordinary day. NOAA notes that the lowest low tides come around the new and full moon (spring tides), so the best days arrive in runs a couple of weeks apart. Plan your trips around those runs, and treat a winter storm followed by a low tide as the best combination you'll get.
Living things are a separate rule
Even where collecting empty shells is unlimited, live animals usually aren't fair game. On Sanibel Island, both city code and a state rule ban taking live shellfish, defined broadly enough to include sand dollars, sea stars and sea urchins (Sanibel Island). On southeastern beaches from spring to fall, stay well clear of marked sea turtle nests and fill any hole you dig (our sea turtle nesting guide explains the season and the law).
Before you go
- Confirm the managing agency for the exact stretch and whether it allows collecting
- Check that day's tides and pick a daylight low tide
- Check the surf and beach hazard forecast, especially on Pacific beaches in winter
- Know any limits (Oregon: one gallon a day, three gallons a year) and seasonal closures, such as plover nesting areas
- Bring a mesh bag, a small hard container for fragile finds, and layers you can get wet
- Plan your exit route before the tide turns
Where to go first depends on what you want to find. For agates, Oregon's Agate Beach and Bandon combine a clear collecting allowance with gravel beds that winter storms uncover — just keep off the offshore rocks at Bandon, which are a national wildlife refuge. For shells, Sanibel is the classic, with no bag limit on empty ones. For something stranger, the quartz pebbles at Cape May's Sunset Beach are free to pick on private land that welcomes collectors.
And if you want to see the famous beaches where you can't take anything — Glass Beach, Ruby Beach, Kalaloch — go anyway. Photograph what you find and leave it for the next tide.
Frequently Asked Questions
Is it legal to take things from the beach?
It depends on who manages the stretch, not on the beach itself. Oregon's ocean beaches allow loose surface material within a daily and yearly limit, Olympic National Park's beaches allow only a handful of empty seashells per visit, and some state parks ban taking glass, rock or driftwood. Check the specific beach before you collect.
When is the best time to go beachcombing?
At low tide, especially a minus tide, and right after a storm. On Pacific Northwest beaches, winter and early spring are best for agates, because storms strip away the sand and expose gravel beds.
Can I take sea glass from Glass Beach in Fort Bragg?
No. Glass Beach is in MacKerricher State Park, where removing the glass is prohibited under California State Parks rules.
How much can I collect on an Oregon beach?
Up to one gallon of loose surface material per person per day, and three gallons per person per year, for personal use. Nothing may be dug out of cliffs, bedrock or the sand itself.
Is a sand dollar a shell I can keep?
Only if it's dead. A live sand dollar is an animal, and places like Sanibel Island ban taking live ones along with live shellfish, sea stars and sea urchins. If you can't tell whether it's alive, put it back in the water.
Do I need any special gear to start?
No. A tide table, a mesh bag and a small hard container for fragile pieces cover a first trip. Waterproof boots help in winter. Spend money on warm, waterproof layers before anything else.
