18m is likely on an ordinary dive, 20m is conveniently accessible, and it is possible to get 30m over the sand after a very long swim. This is the point on the east side of False Bay where the 30m isobath approaches the shore most closely.

Rocky ridges run approximately north-east to south-west. Large outcrops and boulders make rugged relief and provide a habitat for a large variety of invertebrates.
'''Shore dive:''' Very limited parking at the side of Rocklands road (gravel). Turn off the R44 into Anemone street. Drive to the T-junction at the end and turn left into Rocklands road. The road swings to the right and then turns quite sharply to the left. At this point you should see a sloping rock face several metres high in front and a relatively open area sloping down to a series of small ridges and gullies and then the water on the right. Park as near to this corner as complies with the rules of the road, but not on someones driveway.

The path passes to the left of the boulder in the left foreground, then down between the ridges to the centre of the photo. The route continues between the ridges on the left side of the gap.
Walk down between and over rock ridges to the entry/exit point at the side of the main gully. Access is limited to good weather with very low swell, and becomes tricky if south west swell picks up.

The entry point is at the end of this little ridge. The water is quite deep beyond the end of the ridge and it is possible to simply jump off the end of the ridge. Getting out is a bit more of an exercise, as the rock is quite steep and encrusted with barnacles. Watch the sets, choose your moment and scramble up the end of the ridge from the mouth of the gully. Try to get high enough to be out of reach of the next wave before attempting to remove kit. Reinforced kneepads and gloves are highly recommended. It is not a good idea to come into the gully as you will then be caught by the next wave and thrown against the rock. The alternative exit at a ledge just to seaward (left) of this gully is an easier exit in moderate surge and is suitable for use at high tide

Kelp forests inshore and in gully. Lot of interesting invertebrates including a variety of sponges and colonial ascidians, often under slight overhangs.

Good site for close-up photography of invertebrates, particularly sponges and colonial ascidians. (photographic equipment suggestions). [[Image:(views of the entry point)|thumb]View of the inlet. ]
Enter and swim out to the mouth of the gully. There is good diving in all directions, deeper straight out.
#'''Three pinnacles tour:''' Swim out due east over the boulder bottom of the entry gully, keeping to the left wall, through the kelp and ridges beyond the mouth, down onto the wide gully
with flattish bottom and patches of pebbles at 10.5m. Swim along near the gully bottom with high rock on your right hand side. At 13m depth pass a small sand patch, followed by a low, broken ridge across the gully. At 15m, pass a big patch of pebbles, followed by low smooth rock, which looks as if worn by abrasion with stones. Continue past a large rock at 17m depth on the right hand side of the gully with an orange wall sponge to the north, and a small gully branching off about north west. Continue along the side of the wide gully a short distance past a sand patch at 18m to a fairly smooth ridge crossing the gully. The ridge is a couple of metres high and tapers down from north to south and has a notch in the north side of the crest. Turn right and follow this ridge a short distance to the north, where it rises up and becomes the first pinnacle. Just over the ridge at the base of this pinnacle is the Arch, with a pothole to the right of it. Keep the pinnacle to the right and swim past over a patch of sand bottom at about 21m. On the seaward side of the pinnacle are some fairly high rocks which you keep on your right until the second pinnacle. Swim around the south side of this pinnacle and then round to the west, to a gap between two high ridges, with a large rock in the gap. Keep this rock and the next ridge to the right and you will soon come to a large overhang with a silty bottom and a cave a few metres off the bottom This ridge is the third pinnacle. Continue with rocks to the right, past another lower overhang, to a large boulder which has a swim-through under it with about three entries at the bottom and a chimney against the pinnacle. Proceed round the pinnacle clockwise, passing another large overhang at about 18m on the seaward side. There is another lower ridge visible to seaward of this pinnacle. Continue round the pinnacle to the gap and then move to the next ridge to the east. Follow the ridges clockwise and you should end up back at the arch. Head approximately south east through a gap to return to the wide gully at the rock with wall sponge, then keep the high rocks to the left to return to the entry gully. There is a sudden rise at the end of the low open area, and the kelp starts. Keep on a course due east magnetic to get back to the entry gully, which is recognizable by the round boulder bottom and lack of kelp in the middle. Follow the southern wall of the gully until the kelp starts again and surface near the exit point. This is quite a long dive and is best done on Nitrox if you want to spend time looking at things.#For a '''30m shore dive''', swim out approximately 600m on the surface on 290° magnetic. The depth decreases gradually towards the shore, and to avoid decompression (on air) it will be necessary to swim part of the way back in mid-water. Alternatively this can be done on Nitrox or rebreather.
