“Sablinsky caves” ^[2] are abandoned underground mines for the extraction of quartz sand (Sablinskaya suite of Middle Cambrian) used for the production of glass. Most of the "caves" were created in the period from the second half of the 19th century to the beginning of the 20th century . At that time, the industrial and construction boom began in St. Petersburg, and the capital needed a large amount of glass. During the First World War and the revolutions, the glass industry fell into decay, however, mining sporadically continued until World War II . After the cessation of production, the mines switched to the natural mode, and after some time collapses and flooding began in them, which led to the separation of the single development arrays into unrelated fragments, the formation of blockages and secondary gravitational cavities, which only remotely resemble the shape of the initial drifts. The resulting labyrinths are quite complex, and their passage requires some preparation and compliance with safety regulations.

In Sablino there are 4 large caves: Left-bank ("Trash"), "Pearl", "Pants", "Rope" and several small caves: "Three-eyed", "Beach", "Dream", "Santa Maria", "Count Grotto ”,“ Fox Holes ”(local names).

In the cave "Left-bank" 4 species of night-lights wintered, listed in the Red Book of the Leningrad Region , overwinter — a pond nightlight , Brandt's nightlight (mustachioed), watery nightlight , Natterera's nightlight , as well as a northern leather jacket and brown ushanka , or ordinary. ^{[3] [4]}
