The main features of interest at Cae Gwyn are two wetland areas, separated by an area of heathland with outcropping rock. The southern wetland is confined by a rock basin; it has a 'lawn' of bogmoss Sphagnum spp and a profusion of common wetland herbs such as bogbean Menyanthes trifoliata and marsh cinquefoil Potentilla palustris. The flora is distinguished by an abundance of royal fern Osmunda regalis which varies from very large old plants to young plants; other notable species are bog sedge Carex limosa and cranberry Vaccinium oxycoccus. The northern wetland differs in having denser areas of willow and common reed Phragmites communis, but is similar in having numerous plants of Osmunda.
