Another popular site at St Abbs is Seagull Rock, which has a large cave cut out of the seaward side. Unlike the well-known Cathedral Rock, this site is best dived at high water, as the lower the state of tide the more slippery rocks you have to negotiate. The best route is to swim out along the sewage pipe that is clearly visible from the car park. Raw sewage is discharged from this pipe so if you use the toilet on the harbour front before your dive there is a very good chance that you will meet anything you put down it again on your way out. Still, the fish seem to like it, so don’t be put off; just keep your DV firmly in your mouth!
Further up the coast, just around St Abbs head, is Petticowick Bay, a picturesque cove boasting a Divers Only car park. Petticowick is reached either by a short drive through the nature reserve, or by boat from St Abbs harbour. This is an interesting site, mostly kelp, but with reefs where rare marine life has been recorded. Probably the most spectacular sights observed here though are the diving seabirds ‘flying’ underwater. This site is completely sheltered from southerly winds and a good alternative to St Abbs at such times
