The "Strip" is approximately 4 miles long and difficult to walk in the Nevada heat. Fortunately Las Vegas has a great monorail system that takes you the full length of the "Strip" and several additional monorails providing transportation between selected casinos. Below is a map of casino and monorail locations.
