Sledding down an eight-mile track might get your heart racing, but do it at night and your adrenaline levels will hit new highs. The longest floodlit sled run in the world, the track at the Wildkogel-Arena ski area begins at 6,889 feet above sea level. Hit it right and you’ll be able to hurtle down at speeds of up to 30 miles per hour. The run typically lasts for about 30 to 50 minutes but those wishing to extend the adventure can stop at the mid-station bar along the way. You can rent sleds in the village and the trail stays open until 10 p.m. from December through mid-March.
