Difficult to find on flanks of Afon Twrch in a small depression taking a small stream.

Description
A small streamway leads for about 152 metres to a wide bedding plane which is low and wet followed by a tight duck. The stream soon disappears down narrow rifts and the passage continues as a dry sandy crawl. A small inlet enters from the right and two muddy squeezes are negotiated before the passage briefly opens up again. A small chamber can be seen beyond a too-tight squeeze.
