The New Hampshire Fish and Game Department has operated this hatchery on the banks of the Baker River for generations. The facility raises brook trout, brown trout, and rainbow trout that are stocked into rivers and lakes across the state each season. Visitors can walk the grounds, peer into the outdoor raceways filled with thousands of fish at various stages, and watch feeding time — a surprisingly compelling spectacle. Admission is free and the site is open year-round during daylight hours. It is a good stop for families with children, and a useful reminder that most of the trout you catch in New Hampshire started their lives here or at a sister facility.
