Interlaken is only about 1 hour from Lucerne. The town itself is super cute! I read a lot about not staying in Interlaken and instead stay in one of the other small towns outside of the city but I’m so glad we stayed in interlaken itself. We stayed at a great place on an “island”. It’s a small hotel but super quaint and very well staffed. There is a Café on the first floor, which fits right in with the ambiance of the hotel.
There’s a TON of Arabic/Muslim tourist here which is so different from Lucerne
