If you're spending time exploring the Cape Peninsula area of South Africa, a visit with the penguin colony at Boulders Beach is a must. They made Boulders their home (wise penguins) in 1982 and you'll be surprised by how residential the setting is, and how fascinating these birds are when you have the chance to view them at such close range. This is now a protected area for the birds and you'll pay an entrance fee that contributes to their continued, protected well being.
By last count, the colony had grown to 3,000! You'll be able to witness all aspects of their daily life here and might even find a few swimming companions or two if you decide to take a dip in swimming area at the very end of the boardwalk. Be sure to ask where swimming is and isn't allowed and then keep your eyes peeled for a few new friends and want to get a good look at you.
This spot is included in the area known as Table Mountain National Park and information on their hours can be found in the link below.
