Sugar Loaf Cave on the south side of the Isle of Man is one of the most-spectacular dives that I have had the pleasure to experience. This little dive has just about everything you could possibly want – and a bit more. Accessible only by boat, our skipper Deano gave us a thorough briefing on the cave of birds, which would be our first port of call, and what we should expect to see, then it was a backward roll into the clear, cool water.
