Pedra do Alto

Three large rocks, three to five metres tall, rise off a mixed sand and rock bottom roughly fifteen minutes by boat from Albufeira Marina. They are the reef's high points, and dozens of smaller rocks pack in around them, full of holes and cracks. The dive works at a macro pace: peer into one crevice, find a spider crab or a moray head, move to the next. The sand bottom stays shallow enough that nothing here pushes a diver past a straightforward, no-decompression profile. There is no fixed entry point or mapped route; divers work the boulder field as the guide leads, in whichever direction the rocks are busiest that day.

Pedra do Alto is easy to lose in a search. Its name is sometimes merged with Pedra da Oura, a shallower Albufeira reef running half as deep, though whether the two are one site or two distinct reefs has not been settled. It also shares its Portuguese name, tall stone, with an unrelated wall dive off Porto de Mos beach near Lagos, thirty kilometres away, which is not this site under any reading. This is the three-rock reef known locally as Pedra Alta: a small, exploratory stop built for photographers and the life packed into its rock rather than for depth or one big feature. Among the several similar boulder reefs the Albufeira boats work, nothing marks this one out as the pick of the group; its distinguishing feature is knowing which reef you are actually booking.

Entry is boat access only, with no shore option described. Its coordinates sit inside the boundary of the Pedra do Valado marine park, which reserves a small core zone for no activity at all and, separately, permits diving and cetacean watching in a partial-protection zone. Which of the two zones covers this exact reef has not been settled, so check the current status and any permit with whoever runs your trip. No dive centre names Pedra do Alto or Pedra Alta among its regular stops; ask directly if you want it added to a charter.
