Our whole stay in Switzerland will be in the Bernese Oberland region (Lucerne and Murren). It seems to make sense to buy a BO pass, but I'm confused about whether we need the Swiss Travel Pass as well? I keep hearing about the Half Fare card, for instance.
Here is the proposed itinerary for 2 adults/2 kids (feedback/suggestion for activities welcome):
Day 1 Arrive at Zurich airport and take a taxi to Lucern, late night arrival, sleep in Lucern
Day 2 Spend the day in Lucern (boat tour, Mt Pilatus) sleep in Lucern
Day 3 Take early train from Lucern to Murren, explore the Lauterbrunnen valley (hikes?), sleep in Murren
Day 4 Explore Murren (hiking, Schilthorn, Piz Gloria) sleep in Murren
Day 5 Leave Murren toward Zurich via train, explore Zurich and then depart early evening from Zurich airport
Thanks for your help!
