To reach this cave easily from Top Camp, just follow the Tunnocks path until the cave marked on GPS as "1623.p2001-02", then turn right (uphill) and go up a small chive and boulder-filled gully until you see the big boulder with the tag on it.
On a scramble parallel to (east of, uphill from) the path to Tunnocks. Located in a gully filled with wild chives.
The entrance is below a large fixed boulder with the tag on its SW side.
