Due to consistently cold water temperatures between 4 and 6°C, a dry suit is required year-round.

Night diving is permitted, and the site provides air fills and guided tours to assist with navigation.

The thermocline can cause a sudden drop in temperature and a disorienting visual shimmer as you descend, so be prepared with an extra layer and slow down when you hit it. A guided tour is worth considering on your first visit to navigate the wall and wreck safely and avoid entanglement hazards.
Access is via a handrail path above the riverbed, which is not suitable for tourist visits.
