Who We Are
About Us
Cape Peninsula Spelaeological Society
Dedicated to the underground world of the Western Cape
The Cape Peninsula Spelaeological Society (CPSS) is a Cape Town–based, non-profit cave exploration club with a history dating back to 1954. We are dedicated to the safe exploration, recording, and conservation of sandstone- and limestone-based cave systems across the Cape Peninsula and the wider Western Cape.
As part of the broader caving community, CPSS works alongside other member groups of the South African Spelaeological Association (SASA) to support both recreational and scientific endeavours associated with cave systems across South Africa.
We bring together people passionate about spelaeology, adventure, science, and responsible underground exploration. Whether you're an experienced caver or simply curious about the hidden world beneath the surface, CPSS offers a welcoming community built around learning, discovery, and respect for these fragile environments.
Our members explore both established cave systems and lesser-known areas, contributing to the understanding and protection of subterranean environments. We promote safe caving practices, environmental stewardship, and ongoing skills development, while working closely with landowners, researchers, and conservation bodies. CPSS also supports search and rescue efforts through our involvement with Wilderness Search and Rescue (WSAR).
Activities
What We Do
Cave Exploration
Regular trips to cave systems across the Western Cape, from beginner-friendly caves to more technical systems. We explore, survey, and document as we go.
Conservation & Cleanup
We take an active role in protecting the caves we visit. This includes cave cleanups, monitoring of sensitive ecosystems, and education for visiting cavers.
Skills Development
Training in cave techniques, rope work (including SRT), navigation, and safety — for all experience levels.
Research & Documentation
We study cave ecosystems, survey and explore cave systems, and share our findings through our annual bulletin publications.
Community Talks & Events
Talks, presentations, and social events that keep the community connected and engaged.
Collaboration
We maintain relationships with landowners, the South African Spelaeological Association (SASA), and the international community to advance responsible caving across South Africa.
Origins
Johan Meyer & The Moles
The story of caving in the Cape Peninsula began in the early 1900s, when Johan Meyer started exploring the caves of Kalk Bay Mountain. He went on to document over 80 cave systems — 64 of which he is believed to have discovered himself.
Beginning his underground exploration at the age of 59, Meyer completed more than 1,600 ascents of the mountain, often guiding others and sharing his passion. He was accompanied by a group of dedicated companions who called themselves “The Moles.”
Their work laid the foundations for organised caving in the Cape Peninsula. CPSS was formally established in 1954, building directly on that legacy.

Biodiversity
A hidden world of life
Beneath the surface lies a world most people never see. The Cape Peninsula is a hotspot of subterranean biodiversity — caves home to a remarkable range of animals adapted to life underground, many found nowhere else on Earth.
These ecosystems are incredibly sensitive and still not fully understood. Cave-adapted species rely on precise environmental conditions — minor disturbances can cause irreversible damage.
CPSS recognises the importance of these environments and works to promote their understanding and protection.
