Sykehouse is a largely rural area containing a handful of small hamlets. Its northern border is marked by the River Went, while the River Don marks its eastern boundary. The New Junction Canal bisects the parish. It is said to be the longest village in Yorkshire, as it stretches for nearly along its main street. Sykehouse is the origin of the extremely rare Sykehouse Russet apple, an old English variety which was thought to have been lost, but was rediscovered growing in gardens in Oxfordshire and the Doncaster area in 1999.
