    The *Ioannis M* is one of our favourite Mediterranean wrecks, though not for its depth or complexity. Lying upright in just 20 metres, this cargo ship went down in 1985 after a rough patch of weather, spilling its wheat cargo. We love how accessible it is; even newer wreck divers can enjoy a good exploration. You’ll find the bow section relatively intact, still pointed towards the surface as if trying to break free. The stern, however, is a fascinating jumble, crumpled and twisted, leaving swim-throughs and pockets of darkness that are perfect for macro hunting. Look closely along the plates for nudibranchs and flatworms, especially where the light filters through the rust. The deckhouse is a highlight; we often find scorpionfish perched on the rails, blending perfectly with the encrusted metal. Visibility here is usually great, often 20 metres or more, making for some dramatic wide-angle shots against the blue. Dive it in the late morning when the sun is high for the best light penetration into the holds.
