Some tips: sit at the right side of the train from Lauterbrunnen as you can view the beautiful snow capped mountain. I decided to take the Lauterbrunnen route up and the Grindelwald route down as I wanted to hike to the Bachalpsee lake.
Later on, I stop at Grindelwald on the way down. Initially I planned to hike to the Bachalpsee lake for the mirror image lake but sadly it was still frozen..and instead I stop at the first stop via the First cable. It was highly recommended here as well as I felt the whole place was something out of Heidi. Initially I wanted to hike down to Grindelwald but 2 hours journey put me off and finally I decided to take the cable car. From Grindelwald , I stop by Interlaken, another beautiful town by the Alps..
