The parish includes the hamlet of Fawler, about 1⁄2 mile (800 m) west of Kingston Lisle village.

[1] Kingston Lisle was part of Berkshire until the 1974 local government boundary changes transferred the Vale of White Horse to Oxfordshire.

The village is a spring line settlement at the foot of Blowing Stone Hill, which is part of the escarpment of the Berkshire Downs.

The highest point in the parish is Rams Hill, whose top is 764 feet (233 m) above sea level.

Rams Hill is on the Berkshire Downs escarpment about 1 mile (1.6 km) southwest of the village and on the parish boundary with Uffington.

Legend has it that King Alfred the Great blew through it to summon his troops for the Battle of Ashdown in 871.

It passes through the northern extremity of Kingston Lisle parish, about 1+3⁄4 miles (3 km) north of the village.
