IDUNA - Cornwall & Devon

The Iduna, an iron steamship sunk way back in 1882, sits upright on the seabed at 36 metres, a decent depth for an advanced open water diver. We've always found her a captivating dive; the bow is pretty broken up, but the midships and stern still hold their form well. Two large boilers dominate the centre section, giving shelter to crabs and conger eels, while schooling bib and pollock often drift lazily above the deck. The currents here can be tricky, so picking your slack water window is key for a comfortable exploration of this historic wreck.
