Adventure awaits as you go deep inside the only salt mine in the Western Hemisphere with an underground museum. Equipped with hard hat, you will descend 650 feet in a dark elevator to caverns that are 275 million years old. Once there you will find an amazingly large, lighted, salt-lined hallway with hands-on displays, videos, and artifacts. Your ticket includes access to gallery exhibits, a train ride on the Salt Mine Express, and a tram ride (called the Dark Ride) where you will learn about original salt mine workers, their environment, equipment, and their treacherous trip down the shaft. Want more? Sign up for the Safari Shuttle, a tram tour beyond the original museum boundaries into the raw mine area virtually untouched for more than 50 years. Tuesday-Saturday 9 a.m.-3 p.m.; Sunday 12:45-3 p.m. Admission charge. (8 Wonders of Kansas)
