The waterfront is fun with good restaurants and bars and very good Biltong, and get down to the Cape of Good Hope and try sea food platter in restaurant not the shacks above. Wine region is close as mentioned previously for more delights on wine tram. You maybe lucky with sailing competition in town which can also be fun like Volvo etc. Robin island maybe, though I have not been and walking some of the beaches and indeed sea fronts. I also do some fishing, but Mrs Mac likes the large gardens as well. I’m sure you will enjoy and try Red Bus for transportation and site seeing.
Cheers
