Site description
Boulders Bay is situated in Simon’s Town, on the False Bay coast of the Cape Peninsula, 35 km south of Cape Town. The site consists of small beaches holding sandstone boulders and thickets of strandveld vegetation.

Key biodiversity
See Box for key species. Spheniscus demersus, which breed primarily under the strandveld vegetation, but also on the beach and in every available rock crevice, colonized Boulders Bay in 1985. The colony has increased steadily, and there were more than 700 active nests in 1997. This is one of the few growing colonies in the world, and it is thought that birds may be relocating here from Dyer Island (IBA ZA099) where the population has decreased markedly since the mid-1980s. It is also one of only three mainland breeding sites in the world. Small numbers of Phalacrocorax coronatus occasionally roost on the rocks and Haematopus moquini are occasionally seen along the beach.

Non-bird biodiversity: None known to BirdLife International.
