Thit is a compact reef of medium depth, and a pleasant dive. It is close to the slipway at Miller’s Point, but is not dived very often.

Position

• S34°12.987’ E018°28.184’ Alpha Reef GPS -34.21645,18.469733 (Highest point of reef) Bearing to Spaniard Rock 276°magnetic 250 m

This site is in a Marine Protected Area (2004). A permit is required.

Name

The site was previously known as "Outer Spaniard", due to it's proximity to Spaniard Rock, but "Alpha Reef" seems to now be more common usage. This may be a reference to Alpha Dive Centre, which visited the site quite frequently at one time.

Depth

Maximum depth is about 15 m on the sand beyond the rocks. Average about 11 m. Top of the reef at about 2.5 m.

Visibility

Visibility will normally be similar to the visibility at Diving the Cape Peninsula and False Bay/Caravan Reef|Caravan Reef and the wreck of the Diving the Cape Peninsula and False Bay/SAS Pietermaritzburg|Pietermaritzburg, but it can differ from deeper sites in the area, and could be significantly better or worse. Visibility has been known to be around 10 m at Alpha, and nearer 6&npsp;m at Omega at exactly the same time

Topography

The reef is an outcrop of granite corestones in two main sections divided by a sandy bottomed east to west gully. The bigger southern lobe extends to within 3m of the surface, and is also subdivided by a fairly deep gully running from east to west. The southern outcrop slopes up from the south steeply at first and then flattens out and slopes down into the gully, with a steep wall on both sides of the central ridge. The north section starts from the gully and slopes gradually up to the north to about 4m above the sand and then drops quite steeply to the sand. Both sections slope down to the east, where the north section tapers down to nothing. The west end has a few outlying outcrops of various sizes. The south section is about twice the area of the north section and has a deep transverse crack just east of the high point. The reef extends roughly 160m from east to west and about 95 m from north to south and is in a compact group, with few outliers. It has been reported (Zsilavecz 1998) that the reef continues inshore to Spaniard Rock, but there are some fairly large sandy gaps between rocks and it is not always feasible to see from one to the next.

Conditions

The site is exposed to wind from all directions and waves from the south east and south west. The site will usually be at it's best in winter on days when the swell is low, but there are also occasional opportunities during the rest of the year. Conditions will probably be suitable if shore entry conditions are OK and there is no strong offshore wind. The return swim to shore could be a problem in a strong offshore wind (north west). If the south-easter is blowing there may be a slight current setting northwards, and the chop may make shore exit tricky.

Muslim Friendly Travel TO Diving the Cape Peninsula and False Bay/Alpha Reef

-34.21645|18.472|width=|align=Alpha Reef and nearby dive sites}} Usually considered a boat dive. The site is 1.58 km from Miller’s Point at 011° magnetic, but can be done as a shore dive from Rocklands Point. There is adequate parking on the gravel lay-bye on the seaward side of the primary street M4, near the signpost warning against baboons. Access to the shore is poor. There are several steep eroded paths, some worse than others. Choose the one that looks best on the day. All are slippery and steep, with loose gravel. If you have a large group it may be worth arranging a rope for safety, otherwise a walking stick or staff could be useful. It is quite a long swim out to the reef. (about 420 m).

What to See

Marine life

The reef has a zone of heavy red-bait at the top, with sparse Split fan kelp, and lower down is mostly covered by common feather stars with patches of Red chested and Mauve cucumbers, Striped anemones, and Strawberry anemones. The flatter deep sections have some fairly bare areas and quite a lot of urchins and black brittle stars. Also quite a few gorgonian sea fans in the deeper areas, many of which are partially or completely overgrown by other organisms.

Routes

Either swim out on the surface to the reef of go by boat. Position is most easily fixed by GPS. Dive round the reef. After you have seen the reef, either return to the boat or swim back to shore on a compass course. You may wish to visit Spaniard Rock on the way back.

Stay Safe

Hazards

No site specific hazards have been reported. Offshore wind may increase in strength significantly during the dive, making a surface return swim difficult. The path is steep and slippery, specially after rain, and usually in poor repair.

Skills

No special skills are required for boat dives. The site is suitable for relatively inexperienced divers. Ability to navigate by compass, and reasonable fitness and agility are required for a shore dive.

Equipment

No special equipment recommended for boat dives.

A compass is crucial for shore dives to this site as there are sections where there are no reliable monuments. A surface marker is recommended for warning boats of your presence during the long swim, and Nitrox may allow longer dive times without requiring decompression stops. It is theoretically feasible to do the whole shore dive on Nitrox along the bottom, but carrying the required amount of gas down the hillside would be a major effort, never mind carrying the empty cylinders back up after the dive.
