Zermatt is about 3 hours away and is an excellent tourist destination. Worth more than one day, so you can spend a full day there.
<<" must see places from Haut-Nendaz ? Where we can go and comeback on the same day ? According to travel time we can find timerequired to travel, but i would like to know how much time we would take/ devote to each place. (i know it's not that logical, but with any ofyours personal perspective any ball park figure)">>How old is the child, and how physicaly fit are the seniors.
What do you mean by "see" as in "must see" ?
Do you want to look out train windows, see from hiking trails, ride to mountain tops via varous kinds of cable cars, walk around cities?
There is a very nice trail along the older rail route from Hohtenn to Brig. (The BLS Südrampe Trail.) Sections can be accessed at different rain stops. It is a fairly easy walk, but has some ups and downs where good shoes/boots with lugged soles are a good idea. Not sure it would match your family's ages/ desires??
At that time of year, you are near or past the end of of the summer season. Many cable cars and some hotels will be closed for between season maintenance. So, if you want to go up on mountains, please check the timetables for specific dates:
If you leave for Haut Nendaz for Bern at 0840, you'll be there in 2 hours and 16 minutes. Bern is a nice place for a half day visit. Walk through the really nice Old Town, up to the Rosegarden ( there will still be a few roses left in October) look out over the city.
Have lunch at the Rose garden, or at either of two places by the Nydegg Brücke - The old Trolley barn - fun
- or he small very good Brasserie Baerengraben right by the bus stop.. Usually busy.
After lunch, you can walk or ride the tram back to the main station.
Not sure if the Bear pits are functioning. Maybe under repair at the moment? They are right by the Nydegg Brücke, too.
