Roman Rock, in False Bay, is defined by kelp forest reefs, rising pinnacles and a wreck or two sitting alongside artificial reef structures. Shore entries make several sites accessible to beginners, while deeper pinnacles such as Rambler Rock and Castor Rock suit intermediate divers. The marine life leans heavily towards nudibranchs and small catsharks, with Long-nosed Fur Seal encounters a near-constant feature across the area.

A good proportion of sites in Roman Rock are rated for beginners, including shore-entry reefs such as Pyramid Rocks, Boulder's Rock and Millers Point. These sites are shallow and offer kelp forest and reef exploration without demanding conditions. Intermediate sites such as Rambler Rock and Castor Rock are better suited to divers with more experience, as they involve deeper pinnacle diving from a boat.
Shore entries like A-Frame, Pyramid Rocks and Millers Point are generally shallower and well suited to independent diving or those new to the area. Boat-access sites such as Livingston Reef, Friskies Pinnacle and Partridge Point sit further offshore and reach greater depths, offering more complex pinnacle and reef topography. Several sites, including Castle Rock and Noah's Ark, can be reached by either method.
Multiple dive operators service the area, including Impact Divers, Apnea Addicts, The Sundiver, Dive Team, Blue Flash and Bellville Underwater Club, among others.
