The parish includes the south-east portion of the main island of the Bailiwick of Jersey, as well as the Minquiers islets several miles to the south, and is dominated by the broad sweep of the Royal Bay of Grouville.

The name 'Grouville' may derive from: the name Groult or Gueroult is often found today in Normandy and is believed to derive from the ancient probably Norman name Gueroalt (Geirroalt) The Royal Bay of Grouville gained its royal epithet when it impressed Queen Victoria during her visit in 1846.

It is also the main oyster producing area of Jersey, and was also formerly noted for the production of vraic (seaweed fertiliser).

A mediaeval chapel, Notre Dame de la Clarté, built on the Neolithic mound was converted in the 18th century to a folly-like Gothic Revival residence, the Prince's Tower (demolished in the 1920s).

The parish is a first-level administrative division of the Bailiwick of Jersey, a British Crown dependency.

The parish hall is located around 3.9 kilometres (2.4 mi) east of the Royal Square in St Helier.

The parish is dominated by the sweeping Royal Bay of Grouville (part of which is often called Gorey Bay), stretching from Mont Orgeuil Castle in St. Martin, which dominates the skyline to the north, out to the sea in the south at La Rocque.

The parish church and hall are located further inland at the foot of the hill along the main road to St. Helier.
