I don't know if it is still like this, but when I was in Cinque Terra in the Italian Riviera, there was a lot that seem to be structured into the place to have tourism, but not let it overwhelm the place.
Building development was strictly controlled, so the hotel/hostel we stayed at was pretty simple and converted apartment building.
There wasn't a ton to do in the towns, like jet skiiing or parasailing, so the appeal of the place didn't feel like a resort place. It really felt like people mainly made wine there with a few converted buildings that tourists stayed at.
For me, the main draw of the place aside from the natural beauty was the lack of things that seem to cater to tourists.
The second night I was there, we ran into a post-wedding party with locals at a bar who outnumbered the tourists probably 25-1.
And that felt normal. Like, we were there seeing how these people lived and just got to enjoy the lifestyle and beauty for a few days.
Contrast this to Venice, which was almost 100% tourism to me. It felt like a museum. Locals seemed almost out of place. While the buildings weren't new, everything in the town seemed to revolv around selling stuff to tourists.
