# Diving the Cape Peninsula and False Bay/Kalk Bay Harbour Wall

The dive site Kalk Bay Harbour Wall is a shoreline rocky reef and artificial structure in the Kalk Bay area on the False Bay coast of the Cape Peninsula, part of Cape Town in the Western Cape province of South Africa.

The herbour wall site is mostly used for commercial diver training and collecting lead sinkers and other fishing gear lost from the harbour wall.

### Position

* -34.12981718.449451 Kalk Bay Harbor Wall: S34°07.787’ E018°26.967' — (Shore entry and exit point at south-west end of wall). The site is to the east of the breakwater wall of the Kalk Bay Harbour.
Kalk Bay Reef is to the east of the point and southeast of the harbour wall. It is a shallow reef of 9 to 13 m depth on the sand edge, rising to a moderate area of shallow reef above 6 m. It has a few areas which break in moderate seas, which can be seen on the aerial photo. There are also some parches of low reef off the harbour wall a bit further north.
This site is in the Table Mountain National Park Marine Protected Area since 2004. A permit is required.

### Name

The site "Kalk Bay Harbour Wall" is off and near the harbour wall at the small commercial fishing harbour at Kalk Bay.

### Depth

Maximum depth is approximately 9 to 10 m on the sand depending on the tide, and is not much shallower over the reef areas.

### Visibility

Visibility is seldom better than 3 m.

### Topography

Vertical faced concrete harbour breakwater wall with low profile rocky reef at the base, and patches of pebble and sand at about 8 to 9 m depth, There are several concrete blocks and pieces of steel rail near the wall and other garbage including tangled fishing line, old lures, and usually quite a lot of sinkers. The reef extends to about 100 m from the wall.
Geology: Ordovician sandstone, probably of the Peninsula formation, or possibly the underlying Graafwater formation. Strike is about north-west/south-east, more or less perpendicular to the wall, and dip is quite shallow. about 5° to 10°, to the south west.

### Conditions

Avoid strong south easterly winds and large swell. The site is usually at its best in winter but there are also occasional opportunities during the rest of the year
A large swell will make exit tricky. If this appears to be too hazardous, it is possible to swim round into the harbour, where there are ladders and a beach, but this should be considered an emergency option, and the risk of injury by a boat is greatly increased. Keep as close to the wall as possible, and exercise due caution when surfacing. Boat crews will not normally be expecting divers in the water.

### Facilities

If diving from the shore entry below the restaurant: There is a large gravel parking lot at the entrance to the harbour between the railway line and the harbour buildings: -34.12966718.448851 Kalk Bay Harbor parking area: S34°07.780' E018°26.931', clearly visible in the aerial view. Turn left over the level crossing and then right into the parking area. The far end near the buildings is most convenient.
If diving from the breakwater wall: Either arrange to park on the breakwater, which may require getting the chain unlocked, or park in the tarred lower parking lot and carry your kit along the wall.
Public toilets are provided. They are usually open and may be clean. There is a restaurant and cafeteria in the harbour, well known for seafood.

## Get in

Normally done as a shore dive.
Permission is required from the harbour master to dive from the wall, which is the usual arrangement for commercial diver training, as a feature of the site is the 3 m jump entry and ladder exit. For this purpose parking may be arranged on the breakwater at the top of the ladder, which is about half way along the wall. It is recommended that a handrope be attached to a vehicle to aid divers climbing over the edge, as there are not very good handholds on top of the wall beyond the top of the ladder.
Alternative access is from the shoreline rocks outside the harbour, which is in any case a far easier exit. This entry point is at the rocky shore at the end of the harbour wall just below the restaurant. A rock about 8 m from the wall has convenient ledges for entry and exit at low tide.

## Do

Dive at one of the areas listed and explore the vicinity. You could try the roughly 3 m jump entry from the wall and the ladder exit as a training exercise. The water is adequately deep near the ladder. Do this at your own risk, and be sure you use the correct technique, a 3 m faceplant can be both painful and embarrassing, and you could break or lose equipment.

### Marine life

Wall moderately encrusted, no strong zonation. Reef fairly sparsely encrusted, largely encrusting corallines and urchins. Large shoals of juvenile fish in season, mainly Strepies and Blacktail, but also quite a few Hottentot. Anglers jig for Chokka (squid) from the wall at night.

### Features

The 3 m jump entry and vertical ladder exit are useful features for some training purposes, as is the 9 m sand patch near the ladder and the convenience of parking on the sea wall with permission of the harbourmaster.

### Photography

Macro photography is all that is worth trying at this site.

### Routes

* Entry from the wall by jumping in (about 3 m). Exit can be by the ladder on the wall, but it can be a tricky climb, particularly at the top, as the ladder stops slightly short of the top of the wall and the handholds are not abundant. Study the top of the ladder before entry to avoid embarrassment on exit. You may find it more convenient to use a rope to lift your equipment if you are not sufficiently fit and agile to climb a vertical ladder in full kit while holding your fins.
* Entry at rocks at start of wall: dive along base of wall, with occasional short excursions up wall and to side over reef until about half way along wall. Head out about perpendicular to wall along the top of the low reef until you reach the pebble zone, see if you can spot any Cerianthids, then continue to the edge of the sand and along this edge until it turns to the left. Then make your way across the reef more or less North magnetic until back at the wall close to the harbour mouth. Follow the wall back to the entry point, and exit.

### Hazards

Monofilament fishing line. Some with complete with hook, sinker, bait and fisherman on the harbour wall. Nearby boat traffic. Possibility of Great white sharks in the area.
This is a commercial fishing harbour but boats entering and leaving are usually on their way to or from fishing grounds, and do not usually spend any time in the diving area to the south east of the harbour. Recreational anglers commonly fish from the harbour wall and divers must keep a lookout for fishing lines. Sinkers and other fishing tackle are frequently found on the bottom. At night this is a popular squid-jigging site.

### Skills

No special skills are required. This is a popular training area for commercial and scientific divers.

### Equipment

If you intend to go far from the wall a compass and SMB are recommended to help avoid the traffic zone at the harbour mouth, and to alert boats to your presence and position.
