Directions/Parking: EH42 1HX (Nearest Postcode) there is a car park opposite the RNLI station.
Ingress/Egress: The entry point for this dive is located by crossing the harbour bridge heading straight ahead past the crab/lobster pots and then turning left and following the line of the harbour wall to the mouth of Victoria harbour. Here you will find a concrete platform on left side of an arched brick wall and a pebbly beach on the right. Entry and Exit for this dive is the pebbly beach to the right.
Underwater Topography: Enter from the pebbly beach and descend on the shoreward side of the rock where you drop into around 6m of water onto a sandy/pebbly sea bed. Swimming clockwise around the rock, depth increases to around 13m. There are walls rising to the surface and further round a large cave (Johnson's Hole) cutting about 5m back into the rock, tapering all the way back. As you continue round swim into a narrow sheer sided gully which opens up into an amphitheatre in approximately 8m. Outside the gully there is an area of large boulders to explore.
Underwater Directions: From the beach descend and head north to the rock. Then keeping the rock wall on your right shoulder follow its line clockwise round to the seaward side taking in the cave and amphitheatre. On exiting the amphitheatre continue clock wise to an area of large boulders. From here you can continue round to the shore side (depending on air) however because the pebbly beach can be hard to locate we would recommend re-tracing your steps anti-clockwise around the rock of the rock and back to the beach.
Marine Fauna: At the start of the dive on the sandy sea bed Shrimps and Flatfish abound. There is some kelp and in amongst it look out for Lumpsuckers, Nudibranchs and the occasional Octopus. The walls here are covered with Dead Men's Fingers and inside Johnson's Hole crustaceans cling to the walls and Cod hover. The walls of the amphitheatre are covered in Sponges and Anemones and in amongst the boulders look out for Ballan Wrasse and Conger.
Depth: Maximum Depth is approximately 15-18m.
Visibility: Visibility can be decent here but as with many sites around the UK it can be reduced to almost zero following a period of turbulent weather so diving after a period of a few days calm weather and low swell is well advised.
Caution: As you are diving close to the harbour mouth Boat traffic is a possibility so an SMB could be useful. Be cautious of currents on the seaward side of Johnson's Hole
Surface Interval: Check out undiscovered Scotland. There is a busy high street, a beach and the castle remains to peke your interest.

Johnson's Hole Dive Guide: Johnsonís Hole, Dunbar, Scotland - is the name given to a large rocky island lying to the north of Dunbar's Victoria Harbour. It can be dived in isolation or for a longer dive it can be combined with Harbour Reef. If you decide to dive it in isolation then don't worry there is plenty to see here with the centrepiece for this dive being a spectacular amphitheatre located through a narrow gulley on the seaward side of the rock, oh and did we mention that in getting there you have the opportunity to explore the impressive 'cave' which gives this site its name.
