St Abbs
St Abbs dive site
St Abbs is widely regarded as one of the best diving locations in the UK, set within the St Abbs and Eyemouth Voluntary Marine Reserve. The area is known for its clear water, dramatic underwater topography and dense marine life, making it suitable for both training and more experienced divers. :contentReference[oaicite:1]{index=1}
Dives here typically involve exploring rocky outcrops and reef systems such as Broad Craig, Big and Little Green Carrs and the well known Cathedral Rock. These can be dived individually or combined into longer, more varied routes depending on conditions. :contentReference[oaicite:2]{index=2}
The combination of underwater arches, steep reef faces and kelp covered areas creates a visually strong dive site with excellent opportunities to encounter marine life including fish, crustaceans and soft corals.

Dive features
St Abbs offers a range of reef dives centred around rocky outcrops and submerged formations. Popular areas include:
- Cathedral Rock – known for its large arch formation and dramatic swim throughs
- Big Green Carr – a reef system with steep faces and strong marine growth
- Broad Craig – ideal for longer dives combining reef and kelp areas
- Little Carr – shallower sections suitable for training and exploration
Many of these sites can be linked together in a single dive, creating longer routes with varied terrain and depth profiles.
The reef structures provide shelter for marine species, with cracks, ledges and vertical faces attracting a wide range of life. Kelp forests are common in shallower areas, while deeper sections feature exposed rock and increased biodiversity.
Conditions and navigation
Visibility at St Abbs is often better than many UK coastal sites due to the protected nature of the marine reserve, although it can vary depending on weather and sea state.
Navigation is generally based around following reef lines and rock formations. Many dives involve circumnavigating outcrops before returning to the entry point or pickup location.
Care should be taken around exposed areas, as conditions can change quickly, particularly with swell and surface movement.
