The Sea Point Promenade is a popular gathering place for locals to take walks, keep fit by jogging, or have quiet picnics on the green lawn. If, while in Cape Town, you're keen on taking a long walk along the beach without actually walking on the sand, then park your car at Mouille Point (pronounced Moo-lee Point) and take a 3km walk past the light house, Three Anchor Bay, and along to the Sea Point public swimming pool. It's quite a walk, but on a beautiful day there's little that beats it! (Just remember that unless you catch a bus or taxi, there's a 3km walk waiting on the opposite direction. :) )
I've drawn the route for you over here on a Google Map.
Oh, and just for interest sake, the young lady walking in on the left is Kerry-Anne. :)
