Why dive here
With 140+ marine species recorded in the area - including blue whales, dolphins, dwarf minke whales, humpback whales and ocean sunfish (mola mola) - RONA offers some of Scapa Flow, Orkney's richest wreck diving. Water ranges 8-14°C, warmest July, August, September.
The Rona sits upright in 24 metres of water, a former fishing vessel that met its end through fire back in '81. It’s not one of Scapa's colossal German fleet, but it offers a genuinely engaging dive. We love poking around her wheelhouse, which is still largely intact, and you'll find plenty of crabs tucked into crevices. Look out for the resident wrasse patrolling the deck. The Rona is a solid choice for a second dive of the day, or for newer wreck divers looking to get comfortable exploring something smaller and less intimidating.
