I hang in two places more than others...
Elven Forest (friendly to fae and non-human though humans are welcome and they have three scheduled dance parties every weekend):

and,
my friend's sim, Lemongrass Forest, which is also fantasy/nature and public with nice places to explore and riding trails if you like being on horse-back (also lots of good places for photos) and a scheduled dance every Friday:
