A few minutes from the center of Simons Town, on the way to Cape Point, is the turnoff to pretty Boulders (signposted PENGUIN VIEWING), named after a cluster of large granite boulders that form a number of small sheltered bays, providing sanctuary for a breeding colony of African penguins (colloquially known as jackass penguins because of their braying). You can swim at either Seaforth Beach or Boulders Beach, which the penguins visit, but the best place to view them is from the raised boardwalk overlooking Foxy Beach (accessed via the cashier kiosk); they are a treat to watch and almost human in their interactions. A monogamous species, the penguins mate in January and nest from February to August.
