Agate Hunting at Gooseberry Falls State Park, Minnesota
PROHIBITED
Not permitted at this location
Taking agates or any rocks from Gooseberry Falls State Park is prohibited: Minnesota bans rock collecting in every state park except Hill Annex Mine. Look and photograph on Agate Beach, but leave the stones. Rules checked against primary sources in .
Key Conditions
- Minnesota's state park rule bars anyone from disturbing or removing state property in a state park, including "geological formations" (Minn. R. 6100.0900, subp. 1), and the DNR states plainly that "rock collecting is not allowed in the state parks"
- The rule's only rock-collecting exception is Hill Annex Mine State Park on the Iron Range (subp. 2.C), not any North Shore park
- There's no hobby permit: the commissioner's written permission is only for scientific and educational collecting
- Agate Beach at the river mouth and the Picnic Flow shore are inside the park, so the ban covers them
- Breaking a state park rule is a petty misdemeanor, with a fine of up to $300 (Minn. Stat. §§ 85.20, 609.02)

Agate Beach is in the park, and the park is no-collecting
The sandbar at the Gooseberry River mouth carries the DNR's own name, Agate Beach, which is exactly why people assume picking agates there is fine. It isn't. Minnesota's state park rule says no one in a state park may "disturb, destroy, injure, damage, deface, molest, or remove any state property," listing "geological formations" among it (Minn. R. 6100.0900, subp. 1). The DNR's own geology page opens with the line "Rock collecting is not allowed in the state parks and state scientific and natural areas." The only state park where rock collecting is written into the rule is Hill Annex Mine, far inland on the Iron Range.
Gooseberry Falls is the busiest state park in Minnesota: the DNR says it has been the most-visited park in seven of the last ten years, averaging more than 760,000 visitors a year. Many of them walk the River View Trail down to the river mouth and the Picnic Flow shore, where basalt from lava flows more than a billion years old meets Lake Superior. The cobble beaches are full of polished volcanic pebbles, and some of them are agates.
That's the source of the most common search about this shore: can you take rocks from Lake Superior? In Minnesota the answer depends on who owns the ground. The state owns the lake's bed below the ordinary low-water mark, and the DNR doesn't require a permit for low-impact recreational collecting on state-owned lake and stream beds — except where collecting is prohibited, such as state parks. The shore above the waterline belongs to its landowner. Michigan treats its state land very differently, allowing 25 pounds a year, as our Petoskey State Park page explains.

Visiting Agate Beach and Picnic Flow
From the 2026 park map and the DNR fees page, October 2026.
Before You Go
- Bring a water bottle to wet stones — banding shows when they're wet
- Plan to photograph agates, not pocket them; the fine for removing park property is up to $300
- Want to keep what you find? Choose a beach outside the state parks and check who owns it
- Wear boots with grip for the wet basalt at Picnic Flow and watch the waves
- Leave the dog at home if you're heading to the beach
Who Sets the Rules Here
Minnesota Department of Natural Resources
The whole park, including Agate Beach, the Picnic Flow shore and the river: no removing geological formations or other state property (Minn. R. 6100.0900); hours 8 a.m. to 10 p.m. (6100.0600)
Minnesota Department of Natural Resources
Lake Superior's bed below the ordinary low-water mark, which the state owns; outside state parks and scientific and natural areas, the DNR requires no permit for low-impact recreational collecting on state-owned lake and stream beds
Permits & Licenses
| Permit | Required? | Notes |
|---|---|---|
| Agate or rock collecting in the park | No | No permit exists for hobby collecting. Minn. R. 6100.0900 allows collections only for scientific and educational purposes, with the commissioner's written permission. |
| State park vehicle permit | Yes | Needed to park in the park, except at the visitor center / MnDOT wayside lot. Buy it at the visitor center or the entrance kiosk. |
Time & Seasonal Restrictions
- No removing rocks, agates, pebbles or any other geological material anywhere in the park (Minn. R. 6100.0900, subp. 1)
- No collecting anything for resale or commercial use (subp. 2.A)
- Metal detectors may be used in state parks only to find a specific lost item, with the park manager's prior written permission and supervision (subp. 2.F)
- Park hours are 8 a.m. to 10 p.m. (Minn. R. 6100.0600); the MnDOT wayside and visitor center lot stay open around the clock
- No pets on the beaches or in buildings; keep them leashed elsewhere (park rules)
- No swimming at the Upper Falls; no drones in the park
Equipment Notes
- A spray bottle of water or a damp cloth: wet stones show agate banding far better than dry ones, so you can spot and photograph them without taking anything
- A phone or camera with a macro setting for close-ups of banding
- Waterproof boots with good grip for the wet basalt at Picnic Flow
- Leave rock hammers, scoops and sieves at home; there's nothing in the park you're allowed to collect
What People Find Here
- Lake Superior agates, Minnesota's state gemstone since 1969, along with basalt, rhyolite and other volcanic pebbles worn smooth by the lake
- The DNR describes Agate Beach as a sandbar that changes through the year: spring melt-water blasts the river mouth open and fall storms drive waves onto the shore
- Agates range from pea-sized to more than 20 pounds, according to the DNR, though most beach stones are small

Etiquette & Leave No Trace
- Look, wet, photograph, put it back — that's the whole of agate hunting inside the park
- Stay off fragile vegetation above the cobble beach
- Watch the waves at Picnic Flow; the basalt shelves are slippery and Lake Superior is cold all year
- If someone asks whether they can keep a stone, the answer here is no; point them to beaches outside the park

Frequently Asked Questions
Can I take agates from Gooseberry Falls State Park?
No. Minnesota's state park rule bars removing geological formations or any other state property (Minn. R. 6100.0900), and the DNR says rock collecting is not allowed in state parks. That includes Agate Beach and the Picnic Flow shore.
Can you take rocks from Lake Superior?
It depends on whose shore you're on. In Minnesota the state owns the lake's bed below the ordinary low-water mark, and outside state parks and scientific and natural areas the DNR requires no permit for low-impact recreational collecting on state-owned lake and stream beds. Above that line the shore belongs to whoever owns the land, and the DNR warns there's no public strip along the lake: crossing private land without permission is trespassing. In Minnesota state parks the answer is simply no.
How many rocks can you take from Lake Superior?
Minnesota sets no pound limit, because state parks are a flat no and other land follows its owner's rules. Michigan is different: its state land rule allows up to 25 pounds of rocks, minerals and fossils per person per year, state parks included, and the DNR there says that reaches Great Lakes bottomland too (Petoskey State Park).
Is there any Minnesota state park where I can collect rocks?
One. Minn. R. 6100.0900 lets visitors collect rock specimens and fossils for noncommercial use at Hill Annex Mine State Park, subject to posted restrictions. It's an Iron Range mine park near Calumet, not a Lake Superior beach.
Where can I legally hunt for Lake Superior agates in Minnesota?
The DNR points to public Lake Superior beaches outside state parks and scientific and natural areas, river banks and mouths, and gravel pits, but gravel pits only with the landowner's permission. Check who owns a beach before you collect: public access to the water doesn't mean the shore is public.
Why are agates on this beach at all?
The DNR's explanation: more than a billion years ago the continent began to split, pouring out iron-rich lava flows along what became Lake Superior. Gas bubbles trapped in the lava later filled with quartz-rich groundwater that crystallized as banded chalcedony. Glaciers then broke the agates out and tumbled them, and Lake Superior's waves keep polishing them. Picnic Flow is one of those lava flows, exposed at the shore.
