Hi Ross, and welcome to MySwissAlps!
>> We are in La Tzoumaz July 15-20 and then going to Milan July 20. We would like to visit Bern, Lucerne, and Lauterbrunnen during our stay in La Tzoumaz if they are convenient from La Tzoumaz by train.
La Tzoumaz is a remote ski resort and best suited for skiing or hiking in the immediate area (according to the season), rather than visiting other parts of Switzerland.
You get there as follows:
- 8 minute walk to cable car valley station. If you have any slower-than-average walkers in your party, you might consider allowing more time for this walk to avoid missing the last cable car of the day.
From Riddes cable car valley station to La Tzoumaz takes 30-40 minutes. The last cable car of the day to connect with the bus at Isérables leaves Riddes TRI (cable car valley station) as follows:
So, wherever you go, you will need to be back at the cable car valley station in time to catch the last cable car.
Journey times to the places you mentioned visiting would be:
- Bern about 2.5 hours each way
- Luzern/Lucerne about 3.75 hours each way
- Lauterbrunnen about 3.25 hours each way
Morning connections down to the station at Riddes leave the La Tzoumaz, centre bus stop as follows:
- Mon-Fri - 6:48, 7:48, 8:44 and 12:00.
>> Questions: what is the best train tickets option for this itinerary?
Before this question can be answered, you need to plan a detailed day-by-day itinerary, including all trains, buses, boats and cable cars you intend to use, and find out (from the Swiss Timetable) how much they cost, and compare that with the discounts you would get with a Swiss Travel Pass, Swiss Half Fare Card etc. There is information and a spreadsheet here to help you:

>> Are Bern/Lucerne/Lauterbrunnen good day trips from La Tzoumaz given its location and train access?
Not really, due to long travel times and limited transport options from Riddes up to La Tzoumaz. I would consult a map, and the Swiss Timetable, to find out about travel times to destinations closer to La Tzoumaz, such as the area around Lac Léman (Lake Geneva):
