Weekend travel in Europe
My answer to Weekend travel in Europe on Ask MetaFilter
I’ve been using www.atlasobscura.com a lot for travel inspiration recently—it’s particularly good for finding the most interesting/weird things in a given area (it can even do geolocation in your phone to show the most interesting nearby things). I bet you could find some very exciting options there.
I’ve also found the “things to do” section on TripAdvisor to be surprisingly useful. My wife and I have a habit of trying to take the top rated cookery course on TripAdvisor whenever we travel, and it’s lead to some extremely memorable experiences.
