Thrupe Lane Swallet (gbmapping|ST603458) is a 0.5 hectare geological Site of Special Scientific Interest in Somerset, notified in 1992. It is a Geological Conservation Review site.

A Swallet, also known as a sinkhole, sink, shakehole, swallow hole, or doline is a natural depression or hole in the surface topography caused by the removal of soil or bedrock, often both, by water flowing beneath the water-table at considerable depth.

Thrupe Lane Swallet is a small, single pothole cave system that is dominated by a series of deep (117m) and mainly vertical passages, which follow fault lines, natural joints in the rock and mineral veins.
