Using TouristAttraction (typically used for things you go to see) therefore seem wrong. TouristAttraction is also a sub type of Place.

I was not able to find a good taxonomy or vocabulary but here’s a few suggestions for sub types [...] Thanks for raising this, and the suggestions. Before jumping into those specifics I think it's worth pointing out a difficulty we'll all have here: if Schema.org starts to include big enumerated lists it could become rather hard to maintain in the future. This was discussed at last month's workshop; Guha and others suggested that Schema.org should avoid such enumerations. Where they exist already in well established systems, Schema.org could serve as a documentation hub, pointing to those pre-existing lists. In this case, the scope of the list is quite broad --- it's all things of things that people do, or do for leisure. One possibility to investigate here is to look to larger collections to add in such detail. For example using a collection like Wikipedia (or it's RDFization as DBpedia, or the proposed Wikidata work; or Freebase...). At some point with Schema.org we have to say "ok, enough! let's cut over to a larger community-maintained dataset". It is not exactly clear where that cut point should be. There are points within the current schema (eg. http://schema.org/HairSalon) where you could argue the limit has been reached. I wonder how many of the activity-types listed here have nice solid obvious Wikipedia URLs associated with them (and which are handled as wiki Categories), and also whether they are modeled/described in anything like a consistent manner there... cheers, Dan
