Why dive here
With 116+ marine species recorded in the area - including blue sharks, blue whales, dolphins, dwarf minke whales and ocean sunfish (mola mola) - SHAMROCK REEFER offers some of Algarve & Berlengas's richest wreck diving. Water ranges 15-19°C, warmest June, October, November.
The Shamrock Reefer, a 72-meter motor vessel that went down in 1970, lies at a serious depth of 54m off the Algarve coast. We'd definitely call this one a technical dive, purely for its depth, but for those with the training, it’s a rewarding one. The wreck itself is largely intact and has settled upright, making for some dramatic exploration of the bridge and cargo holds if your bottom time allows. Over the decades, schools of sea bream and conger eels have made it home, and the superstructure is covered in colourful jewel anemones. It's a sombre, quiet dive, often with good visibility.
