Forsyth County is north of Alpharetta along both east and west sides of Ga. 400. The east side of Forsyth county borders Lake Lanier.

In 2006 Forsyth County had been in the top ten fastest growing counties of the united States for several straight years. Many new subdivisions with elegant houses have been constructed, several around world class golf courses. Close to Atlanta and the Blue Ridge mountains the area has attracted many of the Metro area's new residents. Shopping continues to expand as the subdivisions fill in the county. Classrooms are technologically-advanced, although an unusually high degree of nepotism is known to exist throughout the school system. Recreation on Lake Lanier, a 37,000 acre Army Corp of Engineers lake, on the east side of the county is enjoyed by many residents and attracts non-residents seasonally.

Much of the eastern side of the county lies on the shores of Lake Sidney Lanier, one of the busiest recreational bodies of water in the nation with 200 miles of shoreline. Created in the 1950s with the impoundment of the Chattahoochee River at Buford Dam, the lake has accelerated the growth of the county, as well as provided recreational enjoyment for many throughout north Georgia. The lake is home to Southern Bald Eagles and Peregrine Falcons, both endangered species.

Forsyth County has been ranked by the U.S. Census as the fastest growing county in Georgia.
