I meant "rail line" not "rail like."

Check out the museum and bar just inside the castle at Gruyere, Giger I believe it's called. Bizarre stuff but cool to see! Gruyere is a great place to spend an afternoon.

Gruyeres - one of the loveliest walled towns in Europe - check out the Cheese Factory just outside the walls.

Palen obviously confounds the village of Boenigen (Lake Brienz) with Interlaken. Lake Thun is outside the boundaries of the village of Interlaken. But Interlaken has a 200 metres long shoreline along Lake Brienz; there is absolutely nothing but a transiting hiking trail (Boenigen - Ringgenberg), however.

The City Park of Thun (Schadau) is of course on Lake Thun. So is the shipyard, the municipal bath and the Bonstetten Park. The conurbation of Thun includes furthermore the villages of Hunibach, Hilterfingen and Oberhofen. Nothing similar at Interlaken.

Spiez is a nice place. But it's not a town, despite the castle. It consists of a railway station, a boat's pier and many small houses and chalets in between, without any center.

Lutry is small and very close to Lausanne, but a nice place. They have a famous Fete des Vendanges in October

There is a beautiful old church in Spiez with some wonderful frescoes inside. But neckervd is right that there is no real town center. I enjoyed it because I stayed in a hotel right on the marina, which was convenient for the ferry ride to other towns.

I enjoyed visiting Oberhafen castle (ferry stops there). Perhaps Thun would make a better overnight, but I liked the smallness of Spiez and the waterfront view from my hotel room/ dining room.

well Thun is not on a lake so you miss the wonderful lakeside/lake views aspect of any hotel in Spiez, which spills over a cliff overlooking the lake.

The City Park of Thun (Schadau) is of course on Lake Thun. So is the shipyard, the municipal bath and the Bonstetten Park. The conurbation of Thun includes furthermore the villages of Hunibach, Hilterfingen and Oberhofen. Nothing similar at Interlaken.

But there is no doubt that Thun has no hotels on the shore of the lake (those are already in the suburbs of Hunibach, Hilterfingen, Oberhofen, etc. linked with the city center by frequent ( all 10 min or so) buses).
From Spiez hotels, you have a fine view over the lake. Don't choose a hotel close to the railway station, however: there run noisy Italy bound goods trains during the whole night (every 10 to 20 min).
Spiez is furthermore a railway hub and hence a good base for day trips by train.

What about the Hotel Freienhof in Thun?

It is right on the river.

I love the covered bridge in Thun.

Sin has its price.

The conurbation of Thun includes furthermore the villages of Hunibach, Hilterfingen and Oberhofen. Nothing similar at Interlaken - but similarly if the nearby villages to Interlaken on Lake Thun or Lake Brienz were technically part of Interlaken then you could say the same thing.

Semantic but the fact that you claim Thun is a lakeside city is simply not true - it is on a river a few miles from where that river drains the lake - the boat dock is right across from the train station - not at all on the lake.
