Petit Lac Des Cygnes

Petit Lac Des Cygnes, which means Little Swan Lake in English, is inspired by the Southwest French countryside, near the foothills of the Pyrenees mountain range, according to the introductory notecard you receive, upon entering the sim.  It is the private home of Cougar Sangria & Henry McAuley, who have graciously opened their home to the public, Wednesday - Sunday.
There are several areas that you can visit on the sim.  There is a quaint cafe, a private dining area called Antoinette's, a maze, the L'Orangerie, and a swimming pool.  The Chateau that you will see on the land is the owners private home, which is not a public area, but with all the things to see and experience, you will be kept quite busy.
There is a group, with a small 25L fee to join, if you need to rezz something for photos, with only the small request to clean up after yourselves.
They do have a 75 script limit and a 200,000 complexity limit active there, so please keep that in mind when visiting and sex is prohibited.
They also have a Flickr group that you can join so you can share with them any photos that you may take of the sim. 
There are many areas for some fantastic photo opportunities.  The landscaping is incredibly detailed and well thought out and the feel is both rustic and quaint, at the same time.  A lot of love, time, and effort was put into the creation of this sim and it's obvious in the amount of detail that you will see here.
