I visited on the Journey To the Center of the Earth Ride at Discovery (a virtual Disney Epcot Center) and thought that the attraction was one of the best things that Second Life has to offer. The attraction, based on a Jules Verne novel of the same name, is a virtual version of the ride at Tokyo DisneySea, and takes you through an underground fantasy world of moving lava, mineral stalactites, and strange plant and animal life. It is one of several great attractions at Discovery, which is celebrating its first Second Life year and will be opening several new attractions later this Spring. I highly recommend you visit.
