Play out your superhero dreams: Dress up as Spiderman and jump out of a 17th-floor window of a building in downtown La Paz! This rappelling adventure is the perfect fix for adrenaline junkies. Pick out a costume to wear, attend a safety briefing, and get fitted and strapped into top-of-the-line equipment by expert guides. Practice on a mini-wall before your 164-foot (50-meter) descent! Rigged into your harness, rappel down the side of the building. When you reach the sixth floor, let go of the rope (and your fears) as you free fall for several seconds before landing on the bottom platform unscathed.
