Hello....I recall that during the 60's being in the area for Conival and beyond when some of the Ferranti Club folks, who were into caving, invited me to go into one of the caves.....looks like it was the image with burn running beside the entrance slot.
Interesting wee tour inside with the classic limestone formations hanging from the roof, tight crawl at one point and eventually a return was made from an area where the water disappeared from a pool.
Much later I came back from reaching Glas Bheinn directly from the road with the interesting walk back across and down to Inchnadamph.
