Signal Hill is at an elevation of 350 metres and offers some of the best views over the city centre, harbour, Waterfront and of course of Table Mountain itself. Signal Hill is a popular spot to bring tourists when the cable car at Table Mountain is closed, but even if you have already been to Table Mountain I think that a drive to Signal is worth it if have the time. There are multiple photo opportunities and you will get a closer perspective of the harbour, historic city bowl and Waterfront.
Approaching Signal Hill, if you make a stop in the bend this is the best spot to view the harbour and historic city centre. It is interesting to see the Castle of Good Hope in relation to the harbour and get a perspective on the land reclamation which has taken place over the last two centuries.
I will point out to you the various historic landmarks and present an idea as to how Cape Town has changed over the last 350 years.
For the adventurists there are a variety of companies offering Tandem paragliding flights which land in Sea Point in front of the Winchester Mansions.
