The western end of Saint Clair Beach was marked for over a century by a series of old wooden posts, the remains of an old breakwater groyne.
This is backed by a series of high dunes topped by a walkway linking Saint Clair Esplanade with the Sir James Barnes Lookout, which offers views across south Dunedin from above Forbury Park Raceway.
In recent years the dunes have been subject to severe erosion, and measures have been taken by the Dunedin City Council to reinforce them.
A 2015 fibreglass statue by Bryn Jones of Mum, a sea lion who repopulated the species along the Otago coast, is located at the east end of St Clair Esplanade, overlooking the tree cover near the promenade.
