McKinney is the county seat of Collin County. It is characterized by rolling hills, mostly covered with trees, unlike the more southern cities in the county.
Even though it is one of the fastest-growing cities in the country, it still maintains a small-town feel, from the historic town square to the Victorian homes in the central part of the city. The square is ringed with independent shops and restaurants, with the Old Collin County Courthouse at its centre.
Two highlights stand out. Towne Lake Park is a city park built around a 22-acre lake encircled by a hike-and-bike trail. The Heard Natural Science Museum and Wildlife Sanctuary, south of town, combines a small museum with 289 acres of native habitat and nature trails. The Heard-Craig House, just off the square, is a well-preserved 1900 family home now run as a museum.
