The Bellisseria Fairgrounds is home to a fun winter area, at least for the next couple days. It's the "Winter Wonderland." To get there, head to the Bellisseria Fairgrounds sim, and on the island away from the shore there's what looks like a cave. Over the entrance is a sign, "Winter Wonderland." Click on the opening to enter. The scenery was made by PrudenceAnton Resident.
There's winter scenery of all kinds from animals going about in the snow to a DJ booth by a pond of ice. But the build will not be up for long. Daniel Voyager stated the place will be up until Friday December 4.
