"Zipping Above Fremont Street A zip line installed down Fremont Street Experience has just gotten bigger and better. Slotzilla is a two-level, 1,700-foot-long zip line that will send riders speeding over the famous downtown pedestrian mall at 35 miles per hour. Wandering along Fremont Street can make for an interesting evening out, but zip lining above it also provides a perspective that you can't get at foot-level. Go during the day for a better view of the world below you, but go at night for the chance to ride near the giant electronic Viva Vision screen, which plays light shows with music.
