Initially a wild flower garden, the 407-hectare Helderberg Nature Reserve was proclaimed a reserve in 1960 to preserve an important enclave of Mesic Mountain Fynbos.
Along with the incredible plant diversity, the reserve has a rich fauna. Visitors can experience bontebok grazing at any time of the day and some 169 species of birds have been recorded. Look out for three types of tortoise – the mountain tortoise, the angulate tortoise and the padloper.
There are several lovely walking trails, of which only the Brown Route is non-circular. Facilities in the reserve include an information centre, plant herbarium, gift shop, indigenous nursery, resource centre, walking paths and benches, Oak Café restaurant, picnic area, facilities for the disabled and ablutions.
