The Fremont Street Experience is mostly known for its overhead light show, Viva Vision, which is an eye-popping visual spectacle. Street performers, impersonators and artists known as buskers are found all along the street level on Fremont Street, making a walk up and down the few blocks under the canopy feel like an adult carnival. A zip line ride, SlotZilla, zooms riders under the canopy and over the heads of the people below. And, of course, every hour after dark the overhead canopy explodes into images and music. During the day, the FSE is a bit more sedate. Pedestrians can stroll from casino to casino and check out the wares at the shopping kiosks. If you're shopping for souvenirs, several places along the FSE feature inexpensive trinkets and tee-shirts.
