Portsea Hole - Victoria

Silver Gardens is one of those Roatán sites we always find ourselves coming back to. It’s a gentle drift along a really healthy wall, topping out at around 19 meters. The shallower sections, maybe 6-8 meters, are our favourite, full of sandy patches where you can often spot a milk conch slowly making its way across the bottom, or if you’re lucky, a pygmy filefish swaying with the soft corals. Deeper down, past the famous black coral formations, you’ll see plenty of green morays peering out from their hidey-holes and big schools of black margates hanging out in the blue. Visibility here is usually excellent, around 19 meters, so you get a great sense of the scale of the reef. We’d suggest going early in the morning before the day boats arrive; it’s a much more peaceful experience. It’s a perfect site for a relaxed second dive, or for photographers who want to take their time looking for smaller stuff like the redlip blennies or the goldspot gobies.
