Eiger North Face located directly above the small town of Grindelwald. This wall has the largest amount of documentet climbing history anywhere.You can take the Jungfrautrain from Grindelwald and it will drop you off at the base of the wall. The right side "Genfer Pillar" offers some outstanding rockclimbing adventurers ranging from 5.10 to 5.13. But be aware this is not sport climbing!!! The central wall offers a wide range of mixed climbs along with all the dangers that make this wall so fantastic.
Here you can find some lines shown on the topo from the Alpinist Magazine.
