Why dive here
With 185+ marine species recorded in the area - including blue sharks, dolphins, dwarf minke whales, humpback whales and ocean sunfish (mola mola) - ISOLDA offers some of South Coast's richest wreck diving. Water ranges 9-15°C, warmest July, August, September.
The Isolda is a real testament to Ireland's wartime history, resting upright at 55 metres off the South Coast. We love how intact she is for a wreck of her age. Dropping down, the bow is often the first thing to loom out of the gloom, usually with a decent current pushing you along her length. You’ll spend most of your time around the superstructure, feeling the cold water on your cheeks, imagining what it was like for the crew when she went down in 1940. The wreck is quite penetrable if you know what you’re doing, with plenty of entry points around the midsection. Inside, the darkness is absolute, broken only by your torch beam picking out pipework and bulkheads. On the outside, we always find conger eels tucked into every nook and cranny, and sometimes a few lobsters scuttling across the deck plates. Visibility can be a challenge here, often sitting around 5-10 metres, so we’d suggest timing your dive for slack water to really appreciate her scale. It’s definitely one for experienced cold water wreck divers who appreciate a bit of history with their dive.
