Harold Porter encompasses mountain slopes with wind-clipped heathlands, deep gorges with relict forests, flats and marshes with restios, sedges and bulbs, as well as dunes adjacent to the beach with specialised salt-adapted plants. The Garden is renowned for its waterfalls and amber pools. Conference Centre Facilities, comprising the Nivenia Hall and the Micro Frog Room are an ideal venue for weddings. The Nivenia Hall, which seats approximately 70 people, has two fireplaces while the Micro Frog Room, which seats approximately 20 people, has one fireplace. The wedding venues may be used separately, or combined through inter-leading doors, making for versatile combinations of space. These venues are serviced by a kitchenette containing a refrigerator, microwave oven and sink. Wide, lath-shaded verandas surround the rooms which in turn lead out onto a lawn edged with attractive water features and flower beds. Toilet facilities are conveniently situated between the facility and the restaurant. A toilet for the disabled and baby changing station are also situated here. Marquee Lawn A secluded area in the centre of the Garden, the Marquee Lawn is surrounded by trees, making it the perfect outdoor venue for weddings. It is big enough to house a marquee tent should one be wary of the likelihood of inclement weather, but has also been used as an open air ‘chapel’ for nature lovers’ weddings. It can easily be closed off from the general public so that the invited guests and participants can have it to themselves. When not in use as a wedding venue, its main feature is a flower bed, where the hard to grow blousterretjies (Nivenia stokoei) flowers in wonderful blue profusion from February into March. Toilet facilities are conveniently situated between the conference facility and the restaurant within easy reach of the area. A toilet for the disabled and baby changing station are also situated there.
