Starting from the Nipple (see walk-in description in open part of site), a less obvious marked path continues.
A very large cave entrance, 20 minutes further on, is an old bivouac used by the Munich cavers, and a few minutes later, a strongly draughting (out in summer) tube about 5m in diameter is the main entrance to the Eishöhle. This was also the site of an old French bivouac, but must have been very cold. Continuing past a large snow-choked entrance and a couple of small holes, all in a cliff to the left, the path ends abruptly and unambiguously at the "new" entrance, also strongly draughting. This is between one and a half and two hours from the car park.
