StandoutExceptional marine biodiversity

Mumbles isn't about depth or big pelagics. This is a proper history dive, sitting just a metre down, making it perfect for an hour's snorkel or a long, shallow free dive. The tug vessel foundered back in 1931, and what's left is a surprisingly intact skeleton, now a home for all sorts of local characters. We love finning slowly over the remains, spotting the resident wrasse darting through the rusted plates. Look closely, and you’ll often find spider crabs tucked into crevices, their legs waving a slow hello. It’s a gentle introduction to wreck diving, especially good for those keen on the historical aspect without the need for heavy gear. We’d suggest going on a calm day; even a slight chop can make it a bit silty. Our favourite time is just after high tide, when the water has had a chance to clear and the sunlight really brings out the colours of the kelp and anemones clinging to the wreck.
