A single day in Cape Town is not a compromise if you plan it around one variable: the mountain. Everything else here is reliable. The cableway is not. This route front-loads the summit, keeps a wet-weather alternative in reserve, and ends where the light does.
06:30 – Land, drop bags, look up
Come out of the terminal and check the summit. If Table Mountain is clear of cloud and the flags are hanging limp, your day is decided. Drop bags at your hotel or in airport storage and head straight for the lower cableway station.
