Above 18m: Diving in the Menai Straits

A depth of 18m or less makes a site suitable for all levels of diver – and first up in this series is the Menai Straits, which separates Anglesey from mainland North Wales. Photography by MARK EVANS and MARTIN SAMPSON

The Menai Straits is a narrow band of water that splits the Isle of Anglesey from the Welsh mainland. Harsh currents rip through here at a serious rate of knots, and it is the last place you’d want to find yourself going for an impromptu drift-dive!
