It lies 2 miles (3 km) south of Grantham, about 60 metres (200 ft) above sea level.
Part of the Roman road of Ermine Street (known locally as the High Dyke) passes through the parish.
[2] It was described in John Marius Wilson's Imperial Gazetteer of England and Wales (1870–1872) as "a parish in Grantham district, Lincoln; on Ermine-street, the river Witham, and the Great Northern railway, 1½ miles N of Great Ponton r. station, and 2 S of Grantham.
Its ecclesiastical parish follows a footpath across the west side of the A1 as far north as Warren Plantation.
Eastwards it crosses the High Dike or Ermine Street (B6403), where it meets the parish of Old Somerby.
At a point 1 mile (1.6 km) east of the B6403, the boundary meets Boothby Pagnell.
[11] It is described by Natural England as "a very good representative example of calcareous [limy] grassland developed on soils derived from Eastern Jurassic Limestone."
[13][14] Little Ponton parish church dates from the Norman period, but is largely of Decorated style.
[15] The dedication is to St Guthlac of Crowland (674–715), a hermit who gained popularity as a saint in the Fens of Eastern England.
