    StandoutRich in charismatic marine life

    Le Sec Aux Murennes in the Medes Islands often gives us a good look at the more substantial Mediterranean residents. You'll likely find moray eels tucked into crevices, their heads poking out with that familiar curious stare. We’ve also spotted barracuda cruising past in loose groups, and the occasional dentex if you’re lucky. It's a solid dive for those who appreciate the robust fish life the Medes is known for, rather than delicate reef scenes. Expect depths around 15-25 metres, generally calm currents, making it a comfortable outing for most experience levels.
