The Alastor is a wreck dive in Strangford Lough, Northern Ireland, the remains of a vessel lying at around 25 meters depth in this sheltered sea inlet. The wreck has become a productive artificial reef in the nutrient-rich waters of the lough, hosting dense marine life including large lobsters, crabs, anemones, and various fish species. Strangford Lough is renowned for its powerful tidal currents — one of the strongest tidal flows in Europe passes through the lough narrows — making precise slack water timing absolutely essential for safe diving. The advanced rating reflects these demanding tidal conditions. The Alastor is a popular wreck for experienced Northern Irish and visiting divers exploring Strangford's diverse underwater environment.
