Port Lockroy Dive Site — Antarctica
About Port Lockroy
Port Lockroy on tiny Goudier Island is Antarctica's most visited historic site — a restored British wartime base now operating as a museum and post office. Beneath the surface, the sheltered harbour offers calm diving conditions rare in Antarctic waters. The rocky substrate is carpeted with giant sea stars — some exceeding 40cm across — alongside forests of feathery hydroids, massive sea urchins, and colonies of delicate bryozoans. Giant isopods (the Antarctic equivalent of woodlice, reaching 15cm) crawl across the seabed. Above, gentoo penguins waddle along the shore before launching into the water as sleek underwater missiles, occasionally buzzing past startled divers. The combination of accessible history and rich invertebrate life makes Port Lockroy a signature Antarctic Peninsula dive.
