All but Outer Castle are shore dives. Someone should stay with your car as a security measure. Then comes Miller’s Point, which lies just beyond the Cape Boat & Ski Boat Club at Rumbly Bay. About 500 metres offshore is the minesweeper Pietermaritzberg at a maximum depth of 21 metres, To avoid surfacing under a Navy patrol boat, phone the operations room at 787-3818 or 787-3821. Incidentally, this also applies back at Boulders and Windmill Beach.

Most other dives are off rocky promontories between the beaches and beyond the city-bound railway line. These occur at Shelly Beach, Glencairn, Sunny Cove, Dalebrook, Danger Beach and St. James. Windmill Beach, is also a good site for training. The 1917 wreck of the Clan Stuart, rests within a short swim from the net or "trek" fishing beach of Mackerel Bay before the naval battery.

Kommetjie has a good dive off the lighthouse. Even better at low tide are outer reefs beyond the channels off the rocky Klein-Slangkoppunt near Long Beach, where rock lobsters can often be found in transverse crevices. There are also three dive-sites back along the main road at Scarborough. The best one is directly in front of the nature reserve, which has very scenic chasms and ledges.

More adventurous is to turn at a well marked intersection into the 7,756 hectare Cape of Good Hope section of the Cape Peninsula National Park. Unfortunately, the best dive-site on the west coast at Olifantsbos is now out of bounds. This is because it lies within a 40 kilometre marine and seabird sanctuary from Schuster’s Bay to the Hoek van Bobbejaan car park. Of the two dive-sites closer to Cape Point - Maclear and Platboom - the former is outstanding. However, it is only safe when the sea has been flattened by a southeaster. Although the water is very cold, visibility can be over 50 metres and the best underwater scenes occur in the west pool. There are other parts well worth exploring, but you need to be accompanied by someone who is familiar with the area.

Further north in the reserve lie Bordjiesrif, Black Rocks and Booiseskerm. The route ends at Venus Pool, but it has a steep drop-off and an unpredictable swell. Many weekend visitors combine diving with bathing and picnicking. During summer months, there are huge crowds and you could get hooked by one of the many anglers.

There are opportunities on both sides of the Peninsula for swimming, snorkelling, spear-fishing and scuba-diving from a chartered boat or from the shore.
