The train into the mountain leaves from Kleine Scheidegg, which can be reached by trains from Grindelwald and Lauterbrunnen via Wengen. The train enters the tunnel running eastward through the Eiger shortly above Kleine Scheidegg. Before arriving at the Jungfraujoch, it stops for a few minutes at two other stations, Eigerwand (on the north face of the Eiger) and Eismeer (on the south side), where passengers can see through the holes excavated from the mountain. The journey from Kleine Scheidegg to Jungfraujoch takes approximately 50 minutes including the stops; the downhill return journey taking only 35 minutes.
