Wide and sandy, St Aubin's Bay is at its best when the tide is up. While St Aubin's is a beautiful, sweeping bay, at low water, you face a long walk and a long wade before you can swim with ease. There are good shops, cafe and restaurant facilities and plenty of parking at many points around the bay though, which has St Helier at its eastern end and St Aubin in the west.

It is also possible to hire jet-skis and to try waterskiing. Elizabeth Castle and St Aubin's Fort lie on small islets in the bay.Originally a fishing village at the opposite end of St. Aubin's Bay from the town of Saint Helier, St. Aubin is now the hub of the parish of St. Brelade. Its name refers to Saint Aubin of Angers.

The Parish Hall is housed in the former railway station. The Railway Walk, a trail following the route of the former railway to La Corbière, starts from St. Aubin.

Saint Aubin's Fort lies in the bay, just outside the harbour. This fort is accessible on foot, on a low tide, via a causeway. It is built upon a rocky islet, and features a tower keep which is surrounded by granite walls and ramparts.

St Aubin On The Hill Church is situated uphill from the harbour.
