Hello, I'll be staying in Grindelwald Grund area with my family for the next 4 nights. I looked at the bus timetables and see that most of the local buses stop around 20:00-21:00, specifically the 121 or 123 bus line. If I am having a late night dinner in Grindelwald, how can I get back home? The distance would be too far to walk especially with 2 children. Thank you for any information you can provide!
