I'm not inworld so I can't offer you SLURLs but you should be able to find these easily. Make sure you experiment with lots of different presets and time of day settings.
Assuming you are looking for foresty type settings:
Botanical in Straylight (Straylight for short)
The Fairy Crossing This the name of both the group and the first sim of a group of nine joined sims. There are many different environments from elven villages to deep forests so tp in to the FC sim and then fly around until you see something you like. There is also a pumpkin hunt on there at the moment too.
Carmarthenshire (2 sims)
Summer (Summer Seale's new sim - there is a link in her picks)
Templum Obscurum. (You need to do some serious exploring if you go there the sims there are like onions - layers and layers of wonder.
The Elven Lands of the Elf Circle community - ElvenGlen is the entry sim. This is some 50+ joined sims including the Fairy Crossing sims and the Isle of Wyrms sims and they contain many lovely places. You have to spend a lot of time exploring them but I remember that some of the northern sims (open your map)
are heavily forested and contain hundreds of lovely locations.
You can also scan some flickr group for good locations - like this group: http://www.flickr.com/groups/732221@N21/pool/
Finally I do NOT recommend that you bother with Avilion - apart from being very laggy, they've become very unfriendly and are ruled (terrorised?) by zealous fashion police who will not allow the outfit you posted in there.
