The faults and the prospecting provided the Cove with some of the largest caves on the Lizard. Victorian tourists went there specially at low tide to see and explore them. The main cave is today known as Torchlight Cave. This cave unusually lies on a fault line running south west underneath and into the cliffside from a location which is only visible by rounding a low promontory on the south side of the cove, or directly from the sea. Once inside it is apparent that it is only partially natural. The Victorians carried no torches and had to resort to burning furze (gorse) torches to find their way. Even with these they could hardly see the roof. On the western side is a rock wall which rises at an angle to the roof and looks like a footwall of an old mine. A chamber has been cut at the highest point, over a distance of about . To the left is a wall of serpentine which looks like a hanging wall. The floor is about 12 feet (3 to 4 metres) in width and rises slightly to the end, which is further on. At the top of the footwall is a 3–4-foot (1 metre) wide vein of pale green soaprock, and at the end is what appears to be a man-made chamber guarded by a partially open passage. Behind it is a mass of pale green soaprock narrowing to a dead end. This is undoubtedly a site of underground soaprock mining, recorded in 18th century Soaprock Leases, but it was also used to store contraband such as brandy, commonly brought over from France by local smugglers.
