The Park Where You Can Legally Keep the Rocks
Most Maine mineral sites are on private land, on club-leased quarries, or hedged with rules that make casual collecting a gray area. Mount Apatite Park in Auburn is different, and that difference is the whole reason to come: this is a 325-acre city park where digging for gems and minerals with hand tools is explicitly allowed in the old quarry area. You do not need a permit, a membership, or anyone’s permission. You just need to understand the boundaries, because the freedom comes with firm limits.
If you are looking for a summit and a view, this is not that hike. Mount Apatite is a low, wooded rise, and the draw is underfoot rather than overhead. Come for the tailings piles of abandoned feldspar quarries, where amateur rockhounds have been sifting for apatite, tourmaline, and quartz for well over a century, and treat the walking trails as the bonus. Set your expectations that way and it is one of the most genuinely unusual free outings in southern Maine.
What You Can Legally Take
The collecting rules come straight from the City of Auburn, which owns and administers the park. Within the area known locally as “the mines,” you may search for and keep mineral and gem specimens under a few clear conditions:
- Hand tools only. Bring a rock hammer, a small pick, a screen, and containers. That is the whole allowed kit.
- No deeper than two feet. You can work the tailings and dig shallow, but the two-foot depth limit is real and it is the line between collecting and excavation.
- No powered equipment. Generators, compressors, pumps, and any other mechanized form of mineral exploration are prohibited.
The hand-tool rule applies to the old quarry tailings, not the whole park, and old workings have loose rock and steep, unstable edges. Do not climb, undercut, or dig into quarry walls, do not bring power equipment, and keep an eye on children near the pits. When in doubt, work the loose piles rather than anything that looks like solid rock face. The City of Auburn brochure and posted park rules are the final word if signage on the ground says otherwise.
These rules exist because the quarries are genuine industrial relics, not a manicured attraction. Gem-quality tourmaline was pulled out of Mount Apatite more than 150 years ago, and commercial and amateur diggers have worked it ever since. The city keeps it open to the public by keeping the impact low, which is what the two-foot, hand-tools-only rule is really protecting.
What You’ll Actually Find
Be honest with yourself, and especially with kids, about the odds. The tailings piles are full of mica, quartz, and feldspar, and you will almost certainly go home with handfuls of shiny, genuinely interesting rock. Books of mica that peel into sheets are common and delight first-timers. Milky and smoky quartz turns up regularly. Chunky pink and white feldspar is everywhere, since these were feldspar quarries first.
The showpiece minerals, the reason the place is named for a gemstone, are the rare ones: apatite in its blue-green crystals, and tourmaline in green and pink. People do still find them. But museum-grade, gem-clear tourmaline is scarce, and the big historic pockets were emptied generations ago. Treat any real tourmaline or apatite crystal as the exception that makes a great day, not the baseline you should expect. The realistic reward is a bucket of mica and quartz and the small, addictive thrill of splitting a rock to see what is inside.
The Trails
Beyond the mines, Mount Apatite has several miles of multi-use trails winding through mixed woods, and the trail network is worth a walk in its own right. Mileage figures genuinely vary depending on which segments you count: the city built about three miles of trail in the mid-1990s, and the fuller network is often cited at closer to eight miles once every spur and connector is added in. Either way, it is enough for a relaxed loop of an hour or two, and the grades are easy.
The trails are shared with mountain bikers and, in winter, with skiers and snowshoers. When there is snow on the ground the city grooms trails here for cross-country skiing, which makes Mount Apatite a rare Auburn park with a genuine four-season use. In the warmer months, the mix of walkers, riders, and rock hunters gives it a friendly, local feel.
Mount Apatite Rockhounding Kit
- Rock hammer and a small pick or pry bar (hand tools only)
- Safety glasses for splitting rock
- A screen or sieve for working the tailings
- Small containers or an egg carton for delicate crystals
- Sturdy closed-toe shoes and work gloves
- Water and a daypack
- Field guide or phone app for identifying minerals
Getting There
The main access for the quarry area is off Garfield Road. From Minot Avenue (Route 11/121) in Auburn, turn onto Garfield Road for about half a mile, turn onto Stevens Mill Road, and park near the baseball fields; the trailhead runs past the armory into the woods. A second entrance, the Small Road trailhead, comes off Hatch Road about a mile and a half from Minot Avenue, then right onto Small Road to its end. Both are free.
Pair a morning at the quarries with the twin-cities’ other quiet outdoor spots: the birding trails of Thorncrag Nature Sanctuary in neighboring Lewiston, a short hike up Sabattus Mountain or Singepole Mountain, or a paddle on Sabattus Pond. It makes an easy full day out of the Lewiston-Auburn area.
The best time to hunt is after a good rain, which washes dust off the tailings and makes crystals easier to spot, and early in the season before the popular piles have been picked over. Look for freshly turned rock where others have been digging, and work the smaller fragments rather than chasing the big, obvious blocks.

Do you need a permit to rockhound at Mount Apatite?
No permit is required for hand-tool collecting in the quarry area. You do need to follow the city's rules: hand tools only, a two-foot depth limit, and no generators, compressors, or pumps.
Is Mount Apatite Park open in winter?
