About this site
Portnagh Rock lies off Donegal in the Atlantic Ocean, offering dramatic underwater scenery. The site features steep walls, rocky outcrops, and abundant marine life, including colorful anemones, crabs, and occasional seals. Strong currents bring nutrient-rich waters, attracting schools of fish. Visibility varies but can be excellent. The rugged topography creates exciting swim-throughs and overhangs. Suitable for experienced divers due to variable conditions. Cold water dive, best with proper thermal protection. A hidden gem for those seeking wild, unspoiled diving.
