Bounce Below: A Giant Underground Trampoline
Beneath the surface of Snowdonia, Wales sits an unused salt mine that has become an amusement park. This park is called Bounce Below, and has nets of trampolines in its caverns. The largest cavern in the mine with trampolines measures 60 meters (196 feet) long and 35 meters (115 feet) high. These vast caverns were first excavated roughly 200 years ago, and have remained largely unchanged.
