During our 2.5 days stay in Grindelwald, we would like to visit Lake Bachalpsee. Reading the forum I understand that we have to take a cable car(Gondola) from Grindelwald to FIRST and then walk up from there to the Lake.
1. Does Swiss pass cover fully the cable car ride from grindelwald to FIRST?
2. How long does this round trip from Grindelwald - lake bachalpsee-Grindelwald take?
