Granny's Pool is a surf-launch boat ramp located along the Umhlanga Rocks promenade, in front of the Pearls Shopping Centre, and serves as the registered launch site for the Umhlanga Ski-Boat Club.

The site was formed naturally by two rocky outcrops that create a sheltered gulley, which historically made it a calm bathing spot and later the natural choice for launching ski boats off Umhlanga.

The launch is classified as a surf launch and is managed by the Umhlanga Ski-Boat Club, with a tractor available to assist vessels in and out of the water.

First-time visiting skippers are required to complete three supervised "in and outs" with a safety officer before launching independently. The Natal Sharks Board also uses the site to access and monitor the shark nets positioned beyond the backline.

While the protected bay offers relatively calm water, rocks remain the primary hazard for launching craft.
