If you visit Cape Town in the summer, relief from the heat awaits at Batstone Pool. This rooftop swimming pool, located in hip De Waterkant, might be small, but the potential for refreshment is large. Think Soho House, but with a more laid-back attitude. It also has great views of Signal Hill and the surrounding neighborhood. Admire them over an afternoon drink and snack with friends. If you're looking for more glitz and socialization on a larger scale, however, I'd head to the Shimmy Beach Club at the V&A Waterfront.
Batstone offers a daily rate and can also host private parties. I recommend booking in advance, especially on hot days. The pool is located on the fourth floor and open Wednesday through Sunday from 11 a.m. until sunset.
