Powderkeg is a roller coaster in Hugo's Hill Street at Silver Dollar City. While it's not the best, it is also recommended. The minimum height to ride is 42 inches.
Powder Keg is an S&S Power launched coaster that hits speeds of 50+ mph in 2.8 seconds before catapulting riders on a twisting, hill-laden track that is designed to provide a sense of flying. Due to the ingenious lap restraint system, riders of almost all sizes can ride, which means the whole family can experience this intense thrill ride together, and air-time is maximized.
Guests between 42" - 48" must ride with an adult companion.
