Woolsthorpe-by-Colsterworth is 94 miles (150 km) north of London, 0.6 miles (1 km) northwest of the village of Colsterworth on the A1 – one of the UK's primary north–south roads. The A1 is the old Great North Road, on which Colsterworth grew. Woolsthorpe is two to three miles from the county boundary with Leicestershire, and four from Rutland.

Woolsthorpe lies in rural surroundings. It sits on Lower Lincolnshire Limestone, below which are the Lower Estuarine Series and the Northampton sand of the Inferior Oolite Series of the Jurassic period. The Northampton Sand here is cemented by iron and in the 20th century the hamlet was almost surrounded by strip mining for iron ore. In 1973 the local quarries closed due to competition from imported iron ore. The same year the Great Northern Railway's High Dyke branch line closed – it was opened in 1916 to carry iron ore, and lay to the north of the village. There was an unsuccessful attempt to preserve the line. The railway's bridge spanned the A1 until it was removed in 2009 during road junction improvements.

Woolsthorpe Manor, Newton's birthplace, is a typical 17th-century yeoman farmer's limestone house, with later farmyard buildings. It is owned by the National Trust and is open to the public.
