Need base location recommendations.
My family of four (2 adults, 10 year old and 8 year old) are visiting Switzerland from 29 Oct - 1 Nov. We are very active. We would like to see the Jungfraujoch and Oeschinen Lake and then get in a few nice day hikes. I was looking at lodging in either Grindelwald, Kanderstag or Feldberg. Any opinions on these areas? Is there another area I should consider? Thank you for your opinions.
