Introduction

Jewel Cave National Monument in South Dakota is known for its extensive cave system, which has been explored for over a century. Visitors come to experience guided tours that showcase unique cave formations and learn about the cave's history, including its discovery by the Michaud brothers in 1900 and its designation as a National Monument by President Theodore Roosevelt in 1908.

The cave system extends for over 200 miles, making it one of the longest caves in the world. Tours vary in length and difficulty, allowing guests to choose an experience that suits their interests and fitness levels. The surrounding Black Hills National Forest offers additional outdoor activities for those looking to explore the area further.
