Also known as the neon boneyard, The Neon Museum is the place where retired neon signs from hotels and casinos find their final resting place. It's best to visit at night - the exhibits are mostly outdoors - when the temperature is cooler and the lights more impressive. Many of the iconic signs like the Stardust and the Moulin Rouge have been fully restored to their original beauty, and the hour-long guided tour will give you a number of interesting historical details about their provenance. Tours sell out fast so plan to book in advance. Tickets are $18. Open daily, weather permitting.
