LAKE SENNEBEC FARM. Have you ever thought about giving your kids the experience of living on a family farm...in Maine? This early 19th century lakefront farm may be the perfect opportunity for your children/grandchildren to learn about living a rural life, raising some farm animals, collecting eggs, eating fresh vegetables from gardens THEY planted, learning a work ethic by doing daily chores, followed by going swimming or fishing on the lake. What better education could you give a child? Sennebec Lake is 3 miles long and ½ mile wide, provides some excellent Bass and Brook Trout fishing. Fed by the St. Georges River, you can kayak up into a nature's paradise for over a mile, viewing a wide variety of wildlife, including eagles and otters. The house and barn, built in 1814, and were totally modernized in the year 2000, while still preserving its classic farmhouse appeal. For fans of old barns, this one is EXCEPTIONAL! It is a post and beam barn kept in almost perfect condition for 210 years.

Currently the property's 24-acre field is used for haying, but a new owner with a new vision could potentially use it for horses, alpacas, a vineyard, an orchard, or for community vegetable gardens. Lake Sennebec Farm is located just a couple of miles from Union, a very active farming village that provides nearby shopping, restaurants and banking, and it is located halfway between Augusta, the state capital, and the best coastal villages of Camden, Rockport, Rockland and Damariscotta.
