On the way between First and Bachsee you enjoy a wonderful view to the Jungfrau massif. In particular, the 3970 meters high Eiger with the long Mittellegigrat and the impressive north face, the great challenge of mountain climbers, can be well seen. Two mountain guides from Grindelwald with an Irish host succeeded with the first ascent to the summit on the 11th August 1858 through the western flank. On the 10th September 1921, three guides from Grindelwald with a Japanese guest climbed for the first time along the Mittellegigrat. By 1932, the Eiger was climbed from all sides, except through the famous and notorious north face, which was considered insuperable for a long time. After numerous tragedies it had been climbed the first time in July 1938 by a German-Austrian rope team with Heinrich Harrer, Anderl Heckmair, Fritz Kasparek and Ludwig Vorg. Even today experienced mountaineers need around two days for this route. However, there are extreme athletes who climb the 1650-meter-high wall alone, unsecured and incredibly fast. The record is held by the Swiss extreme mountaineer Daniel Arnold since April 2011, with 2 hours 28 minutes. The current record in the two-rope team is 4 h 25 min. achieved by the Swiss Roger Schäli and the South Tyrolean Simon Gietl in February 2011.
