About 46% of Hamilton is conserved land, roughly 10,185 acres. There are about 14 miles of mapped trails, and the biggest networks are in Gratiot - Saginaw State Game Area (12.2 mi).
Conserved land, trails, parks and bike routes in Hamilton, measured from OpenStreetMap and USGS data.
Conserved land is a share of the whole town area. Bike lanes are often missing from the map in smaller towns, so that number is likely low.
Conserved doesn't always mean open to visitors. 114 acres are conservation easements, which are usually private land. The places listed above are parks and preserves people visit.

How we measure
"Trails" are OpenStreetMap paths, bridleways, public tracks and unpaved footways, plus footways inside a park or preserve or on a named trail route. Sidewalks are left out. Areas are counted on a 20-meter grid, so overlapping parcels count once. "Conserved" includes conservation easements, which protect land from development but are usually private property. Trailheads are the nearest marked trailhead, public parking lot or information board within about 150 meters of a preserve. Dog rules come from OpenStreetMap when someone has tagged them; otherwise we show what's typical for the land manager, or say the rules aren't recorded.
