The Strip sidewalk in July is not really a sidewalk. It is a 118° pavement bordered by fountains that don’t blow your way and palms that throw shade only in fifteen-foot punctuations. The casinos figured this out about thirty years ago. The current generation of resorts is designed with arcades that open onto the porte cochère, sky bridges that cross the avenues, and through-block passages that let you walk a full mile of Strip without going outside.
The route below stitches the covered segments together. Aria’s east arcade hands you off to the Crystals retail spine, which empties into the Cosmopolitan’s Boulevard tower, which connects via the Las Vegas Boulevard sky bridge to Bellagio, which hands off across the second bridge to Caesars. Every transition is air-conditioned. The only outdoor segments are the sky bridges themselves and the short approaches at either end of the walk — both useful to know about because the bridges have their own micro-weather, and on a windy day you’ll want to brace.
