A 15m wide by 2.5m high entrance is at the side of the track. The right of the entrance has been marked M25 with green paint, but so has site 578.

A large chamber is immediately entered with a short choked passage on the left containing broken pottery. This ends at a draughting constriction which opens beyond. A low crawl over calcite at the back of the cave leads to a high camber with holes in the roof. These must join with site 3392 which is on the main track above. The altitudes of the explored passages in both sites seems about the same.

A man-made tunnel leaves a walled enclosure just inside the entrance and passes under the entrance into the field below. This may possibly have carried water to a nearby barn.

Reference anon., 1990a states that site M25 (presumably 578) has a depth of 195m.
