The 126-acre Trout Brook Preserve located in Alna protects over 4,200 feet of the lower reaches of Trout Brook as well as frontage along the main stem of the Sheepscot River. A half-mile loop trail on the southern portion of the preserve traverses old orchards and pasture lands and affords a look at one of the wider sections of Trout Brook.
From Wiscasset, take Route 218 North for 7.5 miles to the Alna Store. Continue on Rt 218 for 1/2 mile. The preserve parking lot and kiosk are located on the left just past Peaslee Road (on the right).
