I have 6 days 5 nights and really want to do Jungfrau and will base in Grindelwald. how many day should i spend there? And I want to be in Lucerne to do either Pilatus or Titlis. Please help!!
"want to do Jungfrau" - what do you mean? Climb it or ride on the train? Grindelwald to Jungfraujoch is a 78 minute journey (and a VERY expensive one!)
You need 2 nights and 1 full day to go up to fun Titlis, and to see Lucerne's old town. The rest of the time you should spend in the beautiful Jungfrau area, in my opinion.
i want to take a train to the top of Jungfrau and I think I will spend more time there. Thank you for your advice.
