Best for intermediate divers, 5-50m, shore entry, moderate current.
Trolla is a shore-entry reef and wall site in Trondheim, Norway, featuring a structure that descends from 5 to 50 metres. The site is characterised by a dense kelp forest in the shallower sections, transitioning into a deeper wall that provides a clear reference for depth management. Divers should expect cold water temperatures between 4 and 15°C and variable visibility ranging from 5 to 30 metres. Currents are typically moderate but can strengthen, making it essential to plan dives around slack water. Hazards include cold water, low visibility, sea urchins, and strong currents. Night diving is permitted at this location, which typically requires an intermediate skill level.
