From Hurunui Mouth Road, follow the Scenic Drive sign to Gore Bay, on Cathedral Road. Along the way you can also access Manuka Bay and stop at a viewpoint overlooking The Cathedrals. Unfortunately, this view is a bit limited.
The bay itself is very attractive, with a sandy surf beach fringed by mostly holiday homes. There is a campground as well and the Tweedies Gully track takes you to a high point above the bay.
