TOSTO - Scapa Flow, Orkney

Diving the *Tosto* in Scapa Flow offers a solid wreck experience, particularly for those who appreciate history and the atmosphere of a deep, intact vessel. Lying at 49 meters, this 73-meter steamship, sunk by a mine in 1917, is largely upright and still has much of her structure to explore. We’ve found her triple-expansion engine a real focal point, along with the distinct bow and stern sections which are often swarming with pollack and wrasse. Visibility can vary here, as it often does in Scapa, but on a good day, the *Tosto* provides an evocative dive through a piece of maritime history, suitable for experienced wreck divers comfortable with depth.
