Dove Rock is a small plug of basanite surrounded by a narrow inner zone of tuff and an outer zone of partly brecciated inwardly dipping sandstone bounded by a ring fracture. Further incipient ring fractures are seen beyond it. As similar rocks and structures can be seen elsewhere, and as the bathing pool makes access difficult, it is suggested that if time is short both this locality and the seaward side of Castle Rocks could be omitted.

The Kirk Hill Neck is cut off to the cast by the Dunbar-Gifford Fault, but to west and south the margin is vertical and has an irregular outline. The neck filling is again similar to the tuffs of the Old Harbour and bedding is more apparent towards the margins than at the centre. The strike of the bedding is approximately parallel to the neck margin to east and west, but adjacent to the southern margin the strike is variable. The bedding is vertical in the east, but dips westwards away from the centre of the neck at 40-70° in the west. In the north-western part of the neck there is a raft of sandstone measuring 2·5 x 6 m and south-west of the raft there is a 30 cm dyke of sandstone. The latter does not contain flow-banding like the dykes of the Parade Neck. At the indented south margin, tongues of red tuff penetrate the brecciated sandstone wall-rock and the yellow lapilli in this tuff are clearly aligned in flow structure against the sandstone.
