BOULDERS BEACH PENGUINS
Boulders Beach: The Story Behind Its Penguin Colony
How a colony that began with two pairs in 1982 became one of the only places to walk among wild penguins — and why the species is now critically endangered.

The African penguin colony at Boulders Beach, near Simon's Town, began with just two breeding pairs recorded in 1982. Protected from predators and from the historical egg-collecting and guano harvesting that had devastated other colonies elsewhere, the birds settled in among the beach's giant granite boulders and multiplied rapidly through the 1980s and 90s — much of that early growth came from adult penguins relocating from struggling colonies, not only from chicks hatching on site. Regular surveys since have tracked its size, and it remains one of only a handful of land-based African penguin colonies anyone can visit on foot.
A species now critically endangered
African penguins were reclassified from endangered to critically endangered in 2024, after a population collapse of roughly 97% since the early twentieth century and an ongoing annual decline of around 8%. The causes are mostly at sea, not on land: competition with commercial fishing for the sardines and anchovies penguins depend on, shifting fish distributions linked to a changing climate, and lingering historical impacts from oil spills and egg harvesting. Boulders' colony, unusually, has held up better than most against that trend, which is part of why conservationists treat it as a rare good-news story worth protecting closely.
Boardwalks, not open beach
Raised wooden boardwalks run through the dune vegetation and along sections of the shoreline, letting visitors get close to nesting penguins without disturbing the burrows they dig into the sand and bush. A separate stretch of beach is open for swimming alongside the birds, though rules on where visitors can walk exist specifically to protect breeding areas — penguins nest for much of the year, and the colony is at its most sensitive during egg-laying and moulting periods. The reserve is managed as part of Table Mountain National Park, with entry fees that go toward its upkeep.
Why 'jackass' penguins
African penguins were long nicknamed "jackass penguins" for the loud, braying call they use to mark territory and attract mates, a sound often compared to a donkey. It's still the most reliable way to know a colony is nearby before you see it — Boulders can be genuinely noisy at the right time of day. The species is the only penguin that breeds on the African continent, and Boulders sits near the edge of their usual range on this side of the peninsula, making the colony's presence here as much an unusual quirk of geography as a conservation success.
Simon's Town, a naval backdrop
Boulders Beach sits within Simon's Town, a small, historic town on False Bay that has been a naval base since the Dutch East India Company built a dockyard there in the 1740s — the British Royal Navy later took it over, and South Africa's own navy has run it since 1957. The town's Victorian-era waterfront, dry docks and naval museum sit only minutes from the penguin colony, giving a visit a layered feel: a wild colony on one side of town, a working naval base on the other, both shaped by the same sheltered bay.
Conservation you can see
Local rescue organisations rehabilitate injured, oiled or orphaned penguins from Boulders and other Western Cape colonies, and hand-reared chicks are sometimes released back into the wild population here. Signage around the boardwalks explains the threats the species faces and what's being done about them, making a Boulders visit as much a conservation story as a wildlife sighting. It's worth building in unhurried time at the boardwalks rather than a quick photo stop — the colony's behaviour, from nest-building to waddling commutes to the water, rewards watching rather than rushing past.
