A multi-peaked massif, Mt. Pilatus towers over Lucerne and Central Switzerland. Though Queen Victoria enlisted a mule to help her ascend the mountain in 1868, visitors now venture up by cable car or cogwheel train, which—with a gradient of up to 48 percent—is said to be one of the world’s steepest. Crisscrossed by hiking trails and sled runs, Mt. Pilatus features a kid-friendly adventure park and a suspension rope park. From the top, you can see as far as Italy on a clear day.
