The Algarve has exceptional diving in the clear Atlantic waters, with octopus, moray eels, rays and sea bream among the most commonly seen species. Dive sites include wrecks, reefs, underwater arches and the extraordinary walls and caverns of the western Algarve coast.
The Algarve offers exceptional diving in clear Atlantic water, with dive sites around Ponta da Piedade and the western coast featuring underwater arches, caverns, reefs and occasional wrecks, alongside marine life including octopus, moray eels, rays and sea bream. Try-dive and introductory sessions require no certification and are open to most healthy adults and older children, typically from around ten years old, with a short pool or shallow-water skills briefing before the open-water dive; certified divers of any level can join reef or wreck dives suited to their qualification, from PADI Open Water through Advanced and beyond. Full equipment, including wetsuit, BCD, regulator and tank, is included in the quoted price, and dive centres provide weights and fins sized to each diver; participants need only bring swimwear and a towel, though experienced divers sometimes bring their own mask or dive computer. Established Algarve dive centres are PADI or SSI affiliated, employ instructors and divemasters holding recognised professional certifications, and run a dive briefing before each trip covering the site, expected depth, entry and exit procedure, and hand signals, with dive boats carrying oxygen and first-aid equipment and staff trained in emergency response. Visibility and water temperature are best from June to October, when conditions are calmest and warmest; diving is possible outside this window with a thicker wetsuit, but stronger winter swell and reduced visibility limit which sites are accessible.
