Shilin Karst Geological Research Museum

A dense area of boulders and caves filled with winding paths. It's easy to lose the crowds as you wander around between the stones. Try to find the peak viewpoint (just keep going up)—it gives you a stunning view of all the karst. The viewpoint is too small for more than two or three people and the path up to it is narrow, so this isn't really an option for tour groups—which is a shame, as it's a sight not to be missed.
