About this place
Stoke Lane Slocker is a stream cave beside the village of Stoke St Michael in the Mendip Hills of Somerset, England. Formed in Carboniferous Limestone, it runs for roughly 2.18 km and drops about 30 m. This is a site for experienced cavers, not a casual visitor attraction.
What is Stoke Lane Slocker?
The cave is a swallet: a place where a surface stream disappears underground. The water travels through it for almost two kilometres before resurfacing at St Dunstan's Well in the Nettlebridge valley. It was long known as Stoke Lane Swallet, though the local name is now the favoured one. Where "slocker" comes from is uncertain, with one suggestion linking it to an old word for luring or enticing away.
How was it explored?
Early visits date to about 1905. The big breakthrough came in 1947, when cavers reached the first sump and discovered richly decorated chambers beyond it. In the Bone Chamber they found human remains from the Early Bronze Age. Radiocarbon dating and analysis point to at least two adults and three younger individuals.
Can you go in?
The cave lies within a Site of Special Scientific Interest, and entry depends on landowner consent and arrangements managed through local caving clubs. Before planning a trip, contact a Mendip club such as the Wessex Cave Club and ask about current rules; the Mendip Cave Registry & Archive also holds records on the site. The route follows the streamway and passes a sump, so it demands experience, proper equipment and companions who know the system. After rain the water rises and the cave becomes dangerous.
What can non-cavers see nearby?
Without going underground you can walk around Stoke St Michael and the Nettlebridge valley, where old quarry workings shape the landscape. The wider Mendip Hills offer good walking, and the area holds other caves and gorges, though many of those also have restricted access.
When should you go?
For cavers, weather matters more than season. Choose dry spells when the stream runs low, and treat the forecast and your arrangement with the club as part of trip planning.
