Just returned from our trip to Switzerland, which was wonderful and made better by the helpful information here.
I asked a question about vineyards near Lauterbrunnen, and a couple of people mentioned Spiez. Otherwise, I don't remember seeing much information about Spiez here in the forum.
We took a day trip to Spiez via the boat at Interlaken and had a great day. We absolutely loved Spiez and several of our group wished that we had spent more time in that beautiful town.
So when planning your trip to this area, take in to consideration Spiez. There are vineyards, there is an awesome castle with interactive displays, there are lovely restaurants on the waterfront, and a very beautiful location.
